   Product Description    Specifications Videos
The microK standard thermometer has a range that consists of five models, offering measurement accuracies of 0.03 to 0.5ppm, equivalent to 7uK to 0.5mK over the whole range of an SPRT.

The microK thermometry bridge offers performance characteristics and features which are simply not available elsewhere. Internationally available comparable instruments do not achieve the same accuracy or stability (zero drift characteristics with SPRT measurements are not obtainable in any other instrument), do not support the same variety of sensors, and offer considerably fewer operational features. The microK family uses solid state construction with no potentiometers or relays, which ensures long-term reliability and low cost of ownership, two features of growing international importance. Any thermometry bridge at this level will require a large investment. Choose Isotech for the best performance and confidence.

Now offering the MICROK GOLD Package:
  • <30 ppb performance – Guaranteed!
  • ZERO drift for 3 Years
  • 3 Years of ISO-17025 Accredited calibrations
  • 3 Year Warranty
We challenge you to find any other company to report ratio accuracy to this level, measured with the RBC, and who guarantee that for three years.

The MicroK Gold, 70 and 125 models are designed for the Primary Temperature Laboratories, while the MicroK 250 and 500 models were designed for the Secondary Laboratory, as well as a wide range of high-accuracy industrial and scientific calibration applications.

In April 2017 Isotech won the Queen’s Award for Enterprise in the Innovation category for the co-development of the microK. You can read more about this standard thermometer in our news section.
