FlexVu® Universal Display (Model UD30)

Add standalone capability to a large number of gas sensors and detectors

Designed for use with a large number of Det-Tronics gas detectors, the UD30 is approved as a stand-alone device and can perform functions of a gas controller.

Gas level (%), type and unit of measurement are indicated on the digital display. Access to the local event logs and other display capabilities, such as calibration, is accomplished through four (4) magnetic buttons around the display.
