Edinburgh Sensors has released the CO2 Zero Calibration Kit, which allows less calibration gas to be used when checking readings on the firm’s CO2 Guardian monitor range.
The Guardian infrared monitors are said to offer near-analyser quality continuous sampling, measurement and display of target gas concentrations.
The kit – which is used alongside the Guardian NG wall mounted monitor – works by removing CO2 from the air being drawn into the instrument. This provides a cost effective alternative to using nitrogen, which is the usual method for checking zero readings on a CO2 sensor. The zero calibration kit is compatible with any of the CO2 Guardian NG range without modification.
The Guardian NG range has applications in landfill gas measurement, biogas, horticulture and other areas.
