Gas Detector Calibration Service Newcastle

Protecting Australian workers from Toxic Gases and Oxygen-Deficiency

Gas detectors are a vital first line of defense in hazardous environments, protecting workers from toxic gases, oxygen-deficient atmospheres, and explosive vapours. But like any sensitive instrument, gas monitors must be calibrated regularly to ensure they’re providing accurate, life-saving readings. Even a minor drift in sensor accuracy can have serious — or fatal — consequences.

Zokal Safety Services offers professional calibration of portable and fixed gas detection equipment, ensuring your devices meet the manufacturer’s specifications and Australian Standard AS/NZS 60079.29.2. With over 35 years of experience servicing safety-critical instruments, we help you ensure that every reading is trustworthy — and every worksite is safe.

Why Gas Detector Calibration Matters

Gas detectors rely on delicate sensors that degrade over time — especially when exposed to humidity, temperature swings, dust, and chemical vapours. Calibration ensures that sensor output remains accurate, and that alarm set points are triggered at the correct concentrations.

AS/NZS 60079.29.2 and all major gas detector manufacturers recommend:

Calibration at least every 6 months (more frequently in high-risk conditions)
Daily bump testing before use to ensure the unit is functioning properly

Failure to perform these checks can result in false readings, delayed alarms, or total failure to detect a life-threatening atmosphere. Zokal ensures that your detectors are not just working — they’re calibrated, verified, and compliant.

Zokal is the Supplier of ZOGAS for Accurate Calibration and Bump Testing of all Gas Detectors.

At Zokal we can supply specialised gases and gas mixtures to meet various and specific requirements. We work with you to understand your application and analyse your consumption patterns. This way we can offer the correct cylinder size that maximises your efficiency while minimising costs.

We supply High Purity Carrier gases up to 99.999% pure. Our range includes hydrocarbon gases, chemical gases, halocarbons, rare gases and many other gases for research and industry. These gases can be supplied in a range of cylinders up to 200bar in pressure. Contact us for a list of available gases in high pressure cylinders.

Zokal can supply custom made high precision gravimetric calibration gas mixtures and high purity gases, in a range of both compact light weight or much larger type cylinders.

Calibration Gases are manufactured gravimetrically to ISO 6142 and all aluminium cylinders conform to EN12205 / ISO 11118 and are traceable to NPL, UKAS and NIST.
