By allowing both pumped and non-pumped detectors to be calibrated
and tested using the same procedure - with no additional operator
involvement required - the CheckBox IMH greatly simplifies
the whole process. All data is permanently recorded, ensuring
traceable records and can be uploaded and saved for future
access. Gas lot or batch numbers and expiry dates can also
be entered into the CheckBox IMH records and printed on certificates.
The station supports up to eight gas inlets. One inlet provides
air for zeroing - with the remaining inlets allowing up to
seven different calibration gases (or a combination of gas
mixes) to be tested. When testing standard four-gas monitors
(flammable, oxygen, hydrogen sulphide and carbon monoxide),
the device supports the use of quad-mixed calibration gas
- minimising calibration time and gas usage.
The CheckBox IMH optimises gas bottle usage between single
and mixed gases by automatically determining the best gas
bottle or combination of bottles to calibrate each detector.
It does this by comparing the sensor combination to the gas
bottles attached to the system.
