Feature:
1: Advanced imported electrochemical sensor and high-performance micro-controller.
2: Drift is small,Stable performance,Long service life ,Strong anti-interference ability.
3: If the sensor have the abnormal((short circuit,open circuit)will automatic alarm
4:Temperature automatic compensation ,To ensure the high and low temperature measurement accuracy.
5:Output mode: 4-20ma Analog output or RS-485 Digital output.
6:Infrared controller calibration , Need not to open shell,simple to operate.
7;Automatic malfunction diagnosis,the malfunction code indicates the cause of the malfunction,
8:Can be used controller set the alarm point,communication address, etc.
9:Ex Shell, well sealed, corrosion resistance and the anti- EMI/RFI interference ability.
10:It is may use with our company ZK1000 series gas alarm controller together, it also may direct connect the DCS system
ZT1000 Toxic gas detector uses the advanced imported electrochemical sensor and high-performance micro-controller, long service life, drift is small; Automatic temperature compensation function,to ensure the measurement accuracy in high and low temperature; sensor overload protection function. If the sensor have the abnormal(short circuit,open circuit)will automatic alarm; Infrared controller calibration,so need not to open shell,the operation is very simple. ; Output mode:4-20mA Analog output or RS-485 Digital output; It is may use with our company ZK1000 series gas alarm controller together, it also may direct connect the DCS system; the detector is the fixed type installation, It is can be installed in the site of toxic gas leakage indoor and outdoor locations, All-weather monitor the leakage situation of the toxic gas.sensor's shell material take the aluminum alloy or the stainless steel , Oxidation resistance and corrosion resistance .
