Scope of Accreditation
The laboratory is able to calibrate most types of temperature measuring
instruments. The IANZ
Schedule to the Certificate of Accreditation for Thermocal
Laboratory Ltd is stated below. The Schedule
is also available on the IANZ web site.
All measurement uncertainties are based on a confidence interval of at least
95%. Unless stated
elsewhere in this schedule, calibrations are performed at the premises of the
accredited laboratory.
Normal laboratory calibration temperature 22°C ± 2°C.

TEMPERATURE MEASURING INSTRUMENTS |
| (a) | Rare metal hermocouples |
| (b) | Base metal thermocouples (direct reading or by measurement of voltage) |
| (c) | Platinum (and other metallic) resistance thermometers |
| (e) | Thermistors (and other semiconductor) thermometers |
| (f) | Liquid-in-glass thermometers |
