MANUFACTURING DIVISION

Manufactures of Stable, High Accuracy, Temperature CALIBRATION STANDARDS and Measuring Instruments using Platinum RTD or Thermistor Sensors. 

***** ACCREDITATION TO ISO/IEC 17025 *****

Calibration Services All temperature calibrations are traceable to NIST (ITS-90 conformity) and can be used as references when working to ISO-9000. In addition to calibrating sensors, Instrulab also calibrates most temperature instrumentation.
     
  Platinum RTDs

-200ºC to +400ºC, accuracy from ±0.01ºC depending on the type of sensor and your specific requirements.

Documentation includes:

  • Date, model, serial number of the sensor.
  • All ITS-90 coefficients.  All coefficients required to program the Instrulab 4200C Series, Model 4312A instrument, or instruments by other manufacturers.
  • Resistance vs. Temperature table in printout increments of 5º or 10º as required.  Resistance resolution of 0.001 ohms.
     
  Thermistors

-0ºC to 100ºC, accuracy ±0.02ºC

Full range, limited range, or spot calibration at a specific temperature.  Documentation includes date, sensor identification, readings taken, and individualized R vs. T table in ºC and/or ºF in 5º increments, along with programmable constants (A, B, and C).
