At Edinburgh Sensors, we thrive to deliver bespoke solutions to our customers. Following a customer request, the CO₂ Zero Calibration kit was developed, it allows less calibration gas to be used when checking our CO₂ Guardian monitor range.

The Guardian infrared monitors offer near-analyser quality continuous sampling, measurement and display of target gas concentrations. When a customers’ equipment is installed in greenhouses worldwide, it is difficult to keep costs low when transporting cylinders of gas. Furthermore, there are strict rules in place when transporting high-pressure gas cylinders by air. As such, Edinburgh Sensors developed the CO₂ Zero calibration kit without needing a cylinder of gas.

The CO2 Zero Calibration Kit for the Guardian NG wall mounted monitor works by removing CO₂from the air being drawn into the instrument. This provides a cost effective alternative to 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.

Our Guardian NG range has applications in landfill gas measurements, biogas, horticulture and much more.
