Gas Detectors | Versatile Display/Communicator

Supplier: HMA Group

The FlexVu Universal Display reduces spares inventory and simplifies operation.


The Det-Tronics FlexVu Universal Display is a life-safety display that provides non-intrusive calibration, local event logging and 3rd-party performance certs.

This display/communicator reduces spare-parts inventory by working with a wide spectrum of toxic and combustible gas sensors and by operating with industrial communication protocols such as HART® and Modbus. 

Because the FlexVu Universal Display provides non-intrusive magnetic calibration and configuration, a single person working alone can calibrate gas detectors without declassifying a hazardous area.

In addition, the FlexVu display has been third-party performance tested and certified to FM, CSA, and ATEX/IEC. Its reliable construction has an explosion-proof rating and is approved for use in Class I, Division 1, Groups A, B, C, and D classified hazardous areas for all gas types.

"The FlexVu intuitive menu structure simplifies operation by enabling quick device set up and easy access to sensor status information including local alarm and event logs," said Mike Bragg, product marketing manager at Det-Tronics.

"Plus users will like the backlit, heated LCD that clearly displays gas concentration, and alarm and fault status."

Taking advantage of its flexible installation options, users can couple the FlexVu display directly to a single sensor or place it remotely using a sensor termination box. Outputs include analog 4-20 mA with HART, three alarm relays, one fault relay, and RS-485 Modbus.

In its current release, the FlexVu UD10 display operates with the following Det-Tronics gas detectors/sensors (additional gas and flame detectors will soon be added): 

Combustible gases

  • PointWatch IR (PIR9400)
  • PointWatch Eclipse® IR (PIRECL)
  • Open Path Eclipse IR (OPECL)
  • Catalytic Combustible Sensor (CGS) via the 505 transmitter

Toxic gases

  • Nanotechnology Metal Oxide Semiconductor (NTMOS) hydrogen sulfide sensor
  • Electrochemical sensors (C706x Series and GT3000)
