Zero Calibration Kit

Product catalog summary

Key Features of the New Generation Gas Sensors

No calibration gas required, reducing the need for gas cylinder handling.
Compatible with all CO2 versions of Guardian NG.
Zero correction capability increases servicing intervals.

Calibration and Drift

The Guardian® NG NDIR gas monitors experience long-term drift in calibration due to ageing factors affecting IR signal strength. This drift results in a zero reading offset, which can cause significant calibration errors at higher concentrations. The CO2 Zero Calibration Kit offers a convenient alternative to bottled gas for checking and correcting zero offsets.

Zero Calibration Kit

Designed for Guardian NG CO2 Monitors, the kit provides fast, accurate, and reliable zero calibration without the need for power. It is suitable for various applications including TOC, biogas, personal safety, landfill, IAQ, horticulture, brewing, and more.

EDINBURGH SENSORS Infared gas sensors: Guardian Range ZERO CALIBRATION KIT For Guardian NG CO2 Monitors • No calibration gas required • Zero correction can increase servicing intervals • Compatible with all CO2 versions of Guardian NG • Reduced Gas Cylinder Handling The long term drift in calibration of a Guardian® NG NDIR gas monitors is due to a variety of ageing factors most of which result in a small change in the relative strength of the IR signals reaching the detectors. This produces a very slow drift in the zero reading. Due to the nature of the detection process this zero offset produces a much greater calibration error at higher concentrations than at zero. Both offsets are generally fixed by correcting the zero indication. The CO2 Zero Calibration Kit for the Guardian® NG wall mounted monitor provides a convenient alternative to bottled gas for the checking of zero offsets and if necessary, zero calibration.
