The SRT-19 is Seatronx’s 19-inch sunlight readable marine display, listed at up to 1,500 nits on Seatronx’s data sheet. NMEA, the National Marine Electronics Association, named it the Marine Display winner of its 2026 Product of Excellence Awards, announced September 30, 2026. The award is the news. The buying choice is narrower: the SRT-19 or the 300-nit PHT-19, station by station.
Both models list the same 19-inch size and 1280 x 1024 resolution. They differ in brightness and current draw. Choose by name alone and a sunlit station can end up hard to read, or a DC circuit can pick up load nobody planned for. Miss a placement, cutout or touch-connection detail, and you may face a re-order or a rework of the panel opening.
So start with the stations. Match a brightness class to each one, then settle the install details with Seatronx before the order goes in.
What Is the SRT-19?
The SRT-19 is a 19-inch touchscreen display from Seatronx’s PHT-SRT series. SRT stands for Sunlight Readable Touchscreen, and PHT stands for Pilot House Touchscreen. Seatronx’s data sheet lists the SRT-19 as a 19.0-inch, 1280 x 1024 display with a contrast ratio of 1000 and a brightness of 1,500 nits.
Seatronx’s data sheet describes both lines as displays designed for the industrial and marine industries. Power runs on 9-34 V DC, isolated. The screen takes a panel mount or a VESA mount. Video inputs cover HDMI and DVI-D, plus VGA and composite. The data sheet also lists a red night mode.
Seatronx also lists IEC 60945 certification and HDCP compliance for the series.
Seatronx’s SRT and PHT displays list up to 1500 nits, a wide dimming range, front brightness controls, a standard PCAP touch screen and a sealed front panel. The full feature list and the data sheet both sit on the page for Seatronx’s SRT and PHT display series.
In the 19-inch size, you’re picking a brightness class, not a screen size.
How Does the SRT-19 Differ From the PHT-19?
The two share a 19.0-inch, 1280 x 1024 specification. Seatronx’s data sheet lists the SRT-19 at 1,500 nits and the PHT-19 at 300 nits. At 24 V DC, the SRT-19 draws 3.5 A and the PHT-19 draws 1.5 A. Brightness and current are the two numbers that split them.
| Spec | SRT-19 | PHT-19 |
|---|---|---|
| Brightness. | 1,500 nits. | 300 nits. |
| Current at 24 V DC. | 3.5 A. | 1.5 A. |
| Screen. | 19.0 inches, 1280 x 1024. | Same. |
| Contrast ratio. | 1000. | Same. |
| Operating range. | 0 to 70 degrees Celsius. | Same. |
The other three lines match. Both brightness classes of this 19-inch format have also been named by NMEA: its page lists the PHT-19 among the 2025 winners and the SRT-19 among the 2026 winners.
Choose the SRT-19 if the station gets sun through the windows. As a general rule, direct sun can wash out a lower-brightness screen, so the 1,500-nit class may suit that spot. Plan for its 3.5 A draw at 24 V DC.
Choose the PHT-19 if the station stays shaded from direct sun. In general, a shaded station can suit the lower class, with a wide dimming range to bring the screen down at night. It draws 1.5 A at 24 V DC.
Where Does a 1,500-Nit Display Belong on a Bridge?
As a general rule, a 1,500-nit display belongs at a station the sun reaches through the windows, where a lower-brightness screen can wash out. Shaded stations may suit the 300-nit class. A bridge can mix both, chosen station by station. Give Seatronx the exact station and its sun exposure before choosing.
Placement comes before brightness when you pick a sunlight readable marine display. Seatronx describes the series this way: “The PHT-SRT series covers sunlight-readable marine displays for bridge, deck, and industrial visibility needs.” Seatronx adds: “This product is meant to be used indoor only, unless otherwise specified.”
That second line matters. Describe each station to Seatronx, including where the screen will sit and how much sun it gets. Then ask how the indoor-use note applies to that exact spot.
Power belongs in the same conversation. As a general rule, a higher brightness class draws more current. Seatronx’s data sheet puts the SRT-19 at 3.5 A and the PHT-19 at 1.5 A at 24 V DC, so each screen’s figure belongs in the circuit budget.
Say the helm faces the forward windows and a second station sits back from the glass in shade. The helm may call for the 1,500-nit SRT-19, while the shaded station may suit the 300-nit PHT-19. By the data sheet’s figures, that pair adds 5.0 A at 24 V DC to the circuit.
For the broader brightness question, an earlier Seatronx post covers how many nits a bridge display needs.
Night is the other half. In general, the dimming range and red night mode matter for the night watch whichever class you choose. Seatronx’s data sheet lists backlight dimming from 0 to max and a red night mode. Seatronx also lists front brightness controls. Dimming in general gets its own treatment in an earlier post on how a marine display should dim from day to night.
What Did NMEA Award in 2026?
NMEA announced the 2026 Product of Excellence Award winners on September 30, 2026. Its page lists the Marine Display winner as the Seatronx SRT-19. NMEA members and certified marine electronics installers cast the votes.
The same page lists Seatronx’s PHT-19 among the 2025 winners and its VSRT-17 among the 2024 winners. That puts a Seatronx display among the winners for the third year in a row.
Read the award for what it is: a vote by industry members. The brightness and current figures above come from Seatronx’s data sheet, not from NMEA. For a buyer, the award is a reason to put the SRT-19 on the shortlist. Fit still comes from the specification, the placement and Seatronx’s answers to your questions.
What to Confirm With Seatronx Before You Order
Before you order a sunlight readable marine display for a specific station, put these questions to Seatronx. Each one turns a gap in the plan into an answer you can build around.
- Where will each screen sit? Seatronx says the product is meant for indoor use unless otherwise specified, so describe each station’s exact spot and sun exposure.
- Confirm the front panel’s ingress rating on the data sheet with Seatronx, and ask whether it suits the spot you have in mind.
- Ask Seatronx what its ABS certificate for the series covers for your vessel’s class. The certificate lists the SRT-19 by model name.
- Check the 24 V DC draw for the whole set, at 3.5 A per SRT-19 and 1.5 A per PHT-19, against the circuit and the 9-34 V DC input range.
- Confirm the panel cutout of 414.6 x 359.2 mm (16.32 x 14.14 inches) and the front dimensions of 432.6 x 377.2 mm on Seatronx’s data sheet against the planned opening.
- Pick the touch connection. USB is standard, and RS-232 is available by adding -232 to the part number, as in SRT-19-232.
- Compare the 0 to 70 degrees Celsius operating range with the coldest start-up the station sees, and ask whether the external power dimming control the data sheet mentions suits your installation.

Frequently Asked Questions
What do SRT and PHT stand for?
SRT stands for Sunlight Readable Touchscreen, and PHT stands for Pilot House Touchscreen. Seatronx’s data sheet uses those names for two display lines designed for the industrial and marine industries. In the 19-inch size, the SRT-19 is the 1,500-nit version and the PHT-19 is the 300-nit version. Both use a 1280 x 1024 screen with a contrast ratio of 1000.
Can the SRT-19 be dimmed for the night watch?
Yes. Seatronx’s data sheet lists backlight dimming from 0 to max and a red night mode for the SRT-19. Seatronx also lists a wide dimming range and front brightness controls. The data sheet also says an external power dimming control is available, with details from Seatronx. Ask Seatronx whether that control suits your installation before you order.
What touch connection does the SRT-19 use?
The SRT-19 uses a projected capacitive touch screen, which Seatronx lists as a standard PCAP touch screen. Seatronx’s data sheet lists USB as the standard touchscreen connection. An RS-232 connection is available by adding -232 to the part number, so the RS-232 version is the SRT-19-232. Settle the connection before you order, since it changes the part number.
Who votes for the NMEA Product of Excellence Awards?
NMEA members and certified marine electronics installers cast the votes, according to NMEA’s awards page. In the 2026 Product of Excellence Awards, announced September 30, 2026, the Marine Display winner is the Seatronx SRT-19. The specification, the placement and Seatronx’s answers to your questions decide whether it fits a station.
Planning a Sunlight Readable Marine Display for Your Bridge
The choice comes down to each station.
- Consider the 1,500-nit SRT-19 for stations the sun reaches through the windows.
- Consider the 300-nit PHT-19 for stations shaded from direct sun.
- Mix the two classes station by station if the bridge needs both.
- Check the dimming range and red night mode for the night watch at every station.
- Add 3.5 A per SRT-19 and 1.5 A per PHT-19 at 24 V DC to the circuit budget.
- Settle the cutout, touch connection, placement and ABS certificate questions before the order goes in.
When your station list is ready, tell Seatronx which bridge stations you are planning, along with the sun each one gets and the circuit it’ll run on.
