Accurate, Reliable Readings for Hazardous Environments
HTC provides professional calibration and bump testing of gas detectors and environmental meters, ensuring your instruments are ready to respond accurately in critical safety situations. Whether you’re monitoring confined spaces, tracking air quality, or measuring light and temperature conditions, we help you stay compliant and confident.
What We Calibrate
We support a broad range of gas detection and environmental monitoring equipment, including:
Single and multi-gas detectors (CO, Oâ‚‚, Hâ‚‚S, CHâ‚„, etc.)
Confined space monitors
PID gas detectors and toxic gas sensors
Temperature and humidity meters
UV light meters and lux meters
Sound level meters
Air flow and anemometer devices
Our technicians work with leading brands such as Honeywell, MSA, Riken, Dräger, BW Technologies, and more.
Calibration, Bump Testing & Documentation
Each device undergoes functional bump testing and full calibration using certified gas standards. We calibrate to manufacturer specifications and applicable New Zealand workplace safety requirements.
You’ll receive a traceable calibration certificate showing measured values, sensor response, and next test due date. Where required, compliance tags and barcoding are available to help with asset tracking.
Supporting High-Risk Workplaces
HTC’s gas detector calibration services are used by confined space teams, industrial maintenance contractors, utility providers, petrochemical firms, and councils managing environmental hazards.
Regular, certified calibration is essential to detect gas leaks or unsafe environmental conditions before they become life-threatening.
Fast Turnaround & Flexible Options
We offer fast in-house turnaround from our Auckland calibration lab and can provide bulk servicing or mobile testing by arrangement.
Whether it’s one device or a fleet of detectors, HTC ensures your gear is safe, compliant, and ready for work.
