Factory Information


Product Description

T series intelligent toxic gas sensor module is with high response speed, good repeatability and the narrow line error. Also GRI Instrument intelligent technology has the world's most advanced solutions. The high-precision & low-temperature drift and multi-point calibration technology ensure the module measurement accuracy and linearity.

The Module is designed with the digital output. It’s unnecessary to re-calibrate, if the user make the module for binary development or direct use, which will reduce the development and application time cycle. There are two application interfaces: Diffusion, pump-priming.


Main Feature

 1)can accurately detect low or high concentration gases;

2)Adopted the best international amplifier and 24-bit ADC, with high precision, good resolution;

3)Adopted the best international power processing devices to protect the module measurement accuracy and strong anti-interference;

4)Used the multi-point calibration technology to protect the linearity on the high range;

5)Adopted to the high-precision low-temperature drift of the device

6)Two install types: Diffusion, pump-priming;

7)Small size, can be adapted to customer direct application or the second development;
