GTD-5000Tx pumped oxygen and gas detector

■ Built-in sampling pump, faster leak response

■ modular sensor, easy to replace

■ Modbus communication

■ PoE online detection

■ can measure oxygen and more than 100 kinds of toxic gases

■ Fixed gas flow


◤ use built-in sampling pump to achieve toxic gas / oxygen leak quickly respond

 Built-in microprocessor to achieve self-diagnostic function

◤ with a box sensor, the replacement is more simple

◤ use digital flow sensor to maintain a fixed flow

¢ long-term stability of the quality and proven test principle

 Detection of toxic gases below TLV (threshold), excellent performance

◤ excellent LCD display, display a variety of information

¢ 4-digit gas concentration monitor

◤ 4-20mA DC output signal

↑ Easily monitor system configuration by RS-485 Modbus isolated serial data communication or PoE (optional)

 Level 2 alarm, single fault display and relay contact output

◤ 3-wire system

 Single calibration and maintenance
