Gas concentration

Simultaneously and continuously displays gas concentration(s) for all sensors (in ppm, % LEL, or % v/v)

Peak (max)/STEL/ TWA ppm or %

Records exposures and displays on demand

Alarm setpoints

Displayed on activation and on demand

Calibration due date

Days remaining on start-up

Clock

Real-time clock setting displayed on start-up
