Toxic gas detector Product Description 1, when setting the value of a good alarm toxic gas concentration before the device will automatically audible alarm; the same instrument will also spot detected concentrations of toxic gases into the corresponding standard voltage signal (eg 0-5V), the current signal (eg 4-20mA), standard digital signal (such as bus RS485, RS232), the frequency of the signal, Hart protocol signals, CAN2.0 bus signals, radio signals (ZIGBEE, WiFi, nRF, GPRS) and other signals, and then the signal goes to a PLC, DCS, alarm control host PC and other unified display, management and control. 2, with display for toxic gas detector can also be real-time display of gas concentration current detection.
