GTEMP 10-TH Through-hull Temperature Sensor

The Garmin GTEMP 10-TH sensor is designed for accurate and rapid monitoring of water temperature in marine environments. It is particularly useful for monitoring livewell conditions, bait wells, and fishing zones.

The Garmin GTEMP 10-TH sensor provides a temperature detection range from -25 to 60 °C.

The GTEMP 10-TH is a dedicated temperature sensor. Unlike temperature sensors integrated into multifunction transducers, it is specifically designed for this single function.

A dedicated sensor such as the GTEMP 10-TH can provide faster response and more targeted temperature measurement in its installation environment compared to sensors integrated into multifunction probes.

The GTEMP 10-TH sensor has a compact length of 70 mm and a thread diameter of 25.1 mm.

Yes, the Garmin GTEMP 10-TH is designed for fast response and high sensitivity, which is essential for applications where thermal variation is a key factor.

The GTEMP 10-TH sensor integrates via the NMEA 2000® network, ensuring plug-and-play connectivity with existing systems.

Yes, its NMEA 2000® integration ensures connectivity with Garmin navigation systems, as well as B&G or Raymarine.

The GTEMP 10-TH sensor uses NMEA 2000 micro-connectors, compatible with other NMEA 2000 micro-connectors, cables, and devices.

Yes, the GTEMP 10-TH sensor is designed to integrate with an existing NMEA 2000® network, enabling data transmission to compatible displays.

The GTEMP 10-TH sensor connects to the NMEA 2000 network via a T-connector and a drop cable. The drop cable must connect to the top of a T-connector.

For installing the GTEMP 10-TH sensor, you will need the following tools:

A drill
A 25 mm (1 in) hole saw
A 34 to 37 mm (1 1/3 to 1 1/2 in) hole saw for foam-core fiberglass hulls (installations)
Marine sealant
Silicone grease
A metal file (for metal hull installations)
Fiberglass cloth and resin (optional for sealing a foam-core fiberglass hull)
A 25 mm (1 in) cylinder, wax, tape, and casting epoxy resin (optional for sealing a foam-core fiberglass hull)

The GTEMP 10-TH sensor must be mounted on a hull with a thickness between 0 and 57 mm (0 and 2 1/4 in).

If the hull is a foam-core fiberglass, it is critical to properly seal the core to prevent water infiltration that could seriously damage the boat. Preparation involves drilling the hole, then sealing the core inside the hull using fiberglass and resin or casting epoxy resin.

You must use a 25 mm (1 inch) hole saw to drill the hole in the hull from outside the boat.

The transducer must not be installed in a location where it could be subjected to impacts during launching, hoisting, or storing the boat.

The GTEMP 10-TH sensor connects to the NMEA 2000 network using a drop cable and a T-connector. The drop cable must be connected to the top of the T-connector, and the T-connector is part of the NMEA 2000 backbone.

To assign a temperature source:

From the list of NMEA 2000 devices on your compatible display, select the NMEA 2000 transmitting device.Select the device (the sensor).If needed, select Review or Config.Select Temp. Source.Select the temperature sensor location.

Yes, if the displayed temperature data does not match other devices, you can set a temperature offset. To do this:

From the NMEA 2000 device list, select the NMEA 2000 device in question.Select the device.If necessary, select Review or Config.Select Temp. Offset.Enter a value in degrees. A positive value compensates for a measurement colder than reality, a negative value compensates for a measurement warmer than reality.Select Done.

No. The GTEMP 10-TH is a through-hull NMEA 2000 temperature sensor. For depth/temperature measurement, a suitable combined transducer must be selected.
