As Australia’s peak body for measurement, we’re responsible for the physical and national standards for measuring temperature and humdity.
This means we’re responsible for maintaining and developing the standards in our laboratory. It also means we’re responsible for disseminating the standards in Australia, which we do through our suite of client services.
These include:
- calibrating reference-grade instruments and standards
- contract research and development on short-term projects or long-term arrangements
- consultancy and advice on product safety and meeting documentary standards
- design and deliver training in precision measurement, calibrations and thermal emissivity testing.
We deliver most of our services in our Lindfield laboratory. Our services are accredited by the National Association of Testing Authorities (NATA). We deliver some services on-site at our clients’ facilities around Australia.
Calibrating and testing temperature measuring instruments
We calibrate and test most reference-grade instruments and standards that measure temperature and humidity. This includes thermal emissivity testing. Measurements made with instruments we calibrate and test are internationally traceable.
Temperature and humidity measuring instruments we calibrate and test
- fixed point cells
- standard platinum resistance thermometers (SPRTs)
- industrial platinum resistance thermometers (IPRTs)
- digital thermometers
- thermocouples
- radiation thermometers \ thermal imagers
- eissometers
- heat flux sensors
- blackbody sources
- liquid-in-glass thermometers
- mercury-in-glass thermometers
- precision resistance bridges for SPRTs
- surface temperature probesdry block calibrators
- psychrometers with mercury-in-glass thermometers
- electronic and Assman psychrometers
- dew point and frost point hygrometers
- relative humidity (RH) / temperature meters
- custom-built instruments and devices.
Temperature and humidity instrument calibration and testing capabilities
We provide our temperature and humidity measurement capabilities to NATA as part of the accreditation process. This includes measurement ranges for instrument types with associated measurement uncertainties. NATA publish this as our Scope of Accreditation: NMI Temperature Standards Project.
Turnaround times
Our turnaround time for calibrations is usually between 2 weeks and 2 months. Wait times vary depending on demand at the time, and on how complex or rare the instrument is. We liaise with clients to meet their schedule requirements wherever possible.
Calibration and testing service costs
We offer premium calibration and testing services. Our costs reflect the time, detail and depth of the service we provide. This suits clients who need the lowest uncertainties possible, including commercial laboratories accredited by NATA.
NATA-accredited laboratories can provide results directly traceable to the national standards. They can deliver results with uncertainties that meet the needs of most clients in Australia, at more competitive rates.
Request testing and calibration service quotes
We are testing the new NMI Services Portal. The portal allows us to process requests faster and lets you see how your request is progressing.
You can use the portal to:
- submit service requests
- accept quotes
- access final reports.
You need an Australian Government MyID to use the NMI Services Portal.
If you are overseas or unable to get a MyID, you can use the existing webform to request a quote.
