Alarms
•
Explosimetry: 2 adjustable instantaneous thresholds in 0-60 % LEL range
•
Oxygen metering: two adjustable instantaneous thresholds over the cell's whole measuring scale (over-
oxygenation and under-oxygenation)
•
Toxic gas metering (by cell)
•
Two adjustable instantaneous thresholds over the whole range:
-
one TWA threshold
- one STEL threshold
