Temperature and Humidity Calibration Services
Accurate temperature and humidity measurements are crucial for various industrial applications. Regular calibration ensures your instruments perform optimally and meet industry standards. For critical processes, standard lab calibration might not be enough—this is where ISO/IEC 17025 certification from a NATA-accredited laboratory becomes essential,
With certification, your equipment achieves traceability to back to the SI, ensuring accuracy and dependability in every reading.

On Site Calibration Services
We offer on-site temperature and humidity calibration services for a wide range of instruments to minimise disruptions to your operations.
Including industrial/precision calibration services of thermometers, hygrometers, enclosures, medical refrigeration, ovens, furnaces and more. Our expert technicians will visit your facility with our modern calibration equipment, ensuring that your instruments are accurately calibrated without the need for transportation.
In-House Calibration Services
If best accuracy is your objective, then send your instruments to our NATA accredited calibration laboratory, we provide comprehensive in-house temperature and humidity calibration services, with some of the lowest measurement uncertainties in the industry. Our controlled environment and stringent quality control processes guarantee precise measurements and prompt turnaround times.
Temperature and Humidity Calibration Scope
Our calibration scope covers a variety of equipment for temperature and humidity instruments, including:

NATA Accreditation
NWI Group is NATA Accredited to provide comprehensive calibration services for temperature and humidity measuring equipment. Our expertise extends to Reference and Industrial Thermometry, Humidity Instruments, Controlled Enclosures and Environmental Monitoring Devices, ensuring they perform with optimal accuracy.
We offer on-site and in-house calibration services for industrial and precision temperature and humidity equipment, with temperature calibration capabilities ranging from -200°C to 1372°C, maintaining measurement uncertainties as low as 0.011 °C and 0.55%rh for specific ranges.
Our onsite capability covers thermometers from -32°C to 250°C, Humidity from 10%rh to 95%rh, and Enclosures from -80°C to 1100°C. While our purpose-built laboratory covers a very extensive range of products with capability including from -200°C to 1372°C via Electrical simulation, -85°C to 1200°C as a system, 10%rh to 95%rh across a range of 0°C to 60°C for humidity standards.
Our NATA accredited scope also covers environmental chambers, temperature and humidityloggers, dry block calibrators, freezers, furnaces, ovens, and incubators, verifying spatial and temporal uniformity from -80°C to 1100°C. NWI Group follows ISO-accredited methodologies and in-house SOPs to ensure traceable, reliable, and compliant calibration processes.
