Det-Tronics GTSNH3100PNES (009471-305) is a GTS electrochemical sensor module for ammonia (NH3), 0 to 100 ppm, for the GT3000 series toxic gas detector. It plugs into a GTX transmitter, which provides a 4-20 mA output with HART proportional to 0-100% of full scale.
The electrochemical cell uses capillary diffusion barrier technology for accurate, stable and selective measurement, which reduces false alarms from other gases and can extend calibration intervals. Sensors are factory calibrated, and the transmitter reads the gas type and range from the module, so a replacement module can be hot swapped without declassifying the area.

Installation notes
- Hot swappable, intrinsically safe sensor module.
- The hydrophobic filter can be replaced without opening the device or using tools.
- Calibration is started at the detector, at a UD10/UD20 display, or with a HART device.
- Background ammonia can shorten sensor life.

FAQ
Is this a complete gas detector?
No. It is the GTS sensor module. A complete GT3000 detector is a GTS sensor module connected to a GTX transmitter module, which generates the 4-20 mA output with HART.
Can the sensor be changed with power on?
Yes. The GTS module is hot swappable and intrinsically safe, so it can be replaced without declassifying the area.
How long does the sensor last?
Expected operating life of the GTS is 2 years in open air, with 6 months shelf life in factory sealed packaging. Background ammonia concentrations may shorten the life of the sensor.
Is it calibrated from the factory?
Yes. Sensors are factory calibrated, and the transmitter reads the gas type and range from the module.
