TGas-1031 fixed ammonia meter
TGas-1031 Fixed Ammonia Meter
Brief introduction
TGas1031 fixed ammonia meter can detect the concentration of ammonia(NH3) gas, and offer 3 signals: a 4~20mA analog signal, a RS485 communication signal, and a switch signal. The signals usually are used to run the remote communication transmission and remote drive.
The meter comes with a remote control, and an alarm which is optional. The remote control can calibrate the transmitter without opening the cover of transmitter.
