Det-Tronics GTSH2S+20PSEE (009471-341) is a GTS toxic gas sensor module for hydrogen sulfide, range 0-20 ppm, for the GT3000 series. The electrochemical cell is built into the module, which plugs into the GTX toxic gas transmitter and can be hot-swapped. This is an H2S+ (Plus series) sensor, certified SIL 2 capable, with an English label and the enhanced shielding housing.

Compatibility and installation notes
- Works with the Det-Tronics GTX toxic gas transmitter; the GTS sensor module and GTX transmitter are ordered separately.
- Intrinsically safe design; the hydrophobic filter can be replaced without opening the device or using tools.
- Event and calibration logs are stored in non-volatile memory and can be read with a UD10/UD20, a HART device or AMS software.
- Field calibration can be started at the detector, at a UD10/UD20 display or from another HART device. H2S calibration kits are listed in manual 95-8616 (for example 010274-001, 10 ppm).
