The Secondary Laboratory utilises stirred liquid baths, fluidised furnaces and high temperature spherical furnaces to provide stable isothermal volumes which facilitate comparison calibration at temperatures from -196.798°C to 1300°C.
Additionally the Secondary Laboratory also maintains a set of slim fixed point cells from the Triple Point of Mercury (-38.8344°C) through to the Freezing Point of Aluminium (660.323°C).
The measurement systems in operation comprise precision thermometry bridges in the microK 400 and ASL F18 coupled with Model 909 and 670SQ Standard Platinum Resistance Thermometers and Tinsley 5685A Standard Resistors. For the higher temperatures the lab utilises two groups of NPL traceable type R Standard Thermocouples.
Secondary laboratory calibration scope:
- Resistance Thermometers (PRTs, SPRTs, Thermistors, etc..)
- Resistance Thermometer and indicator systems
- Noble Metal Thermocouples
- Base Metal Thermocouples
- Thermocouple and indicator systems
- Electrical simulation of temperature measuring instruments
- Electrical calibration of temperature simulators
Plus other manufacturer’s sensors including KAYE IRTD’s, RENISHAW sensors, HP sensors and many more.
How NTPL Can Help
Flexibility to calibrate sensors and systems that most other labs would not undertake.
Many unique calibration techniques have been developed with customer’s, to provide ground breaking uncertainty levels for established instruments or those in the development stage providing priceless evaluation data.
Special prices based on multiple thermometer calibrations.
Special pricing structure for Thermometer and indicator systems.
