Det-Tronics UD10
The FlexVu® Model UD10 is recommended for applications that require a gas detector with digital readout of detected gas levels as well as analog 4-20 mA output with HART, relay contacts, and Modbus RS485 (FOUNDATION™ Fieldbus option available).

The UD10 Universal Display Unit is designed for use with Det-Tronics gas detectors such as GT3000, PIR9400, PIRECL, OPECL, C706x, Model 505/CGS, CGS or NTMOS, as well as generic linear 4-20 mA sensors. The display unit is designed and approved as a ‘stand-alone’ device and performance all the functions of a gas controller.
