MicroK Precision Thermometry Bridge

Thermometry Bridge for Thermocouples, SPRTs and Thermistors

The MicroK 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. The instruments use a completely new measurement technique to achieve accuracies better than 0.02 parts per million (ppm).

When used with a 0C cold junction reference unit, or by measuring the junction temperature with a PRT on another channel the instrument is capable of low uncertainty precision thermocouple measurements, with a voltage uncertainty of just 0.25μV, equivalent to 0.01C with a Platinum / Gold Thermocouple at 1000C.

The microK range consists of four instruments offering a choice of measurement accuracy of 0.07 to 0.5ppm over the whole range, equivalent to 0.07mK to 0.5mK over the whole range of an SPRT with an Ro >2.5Ω. Better at unity ratio.

The instruments in the microK range offer performance characteristics and features which are simply not available elsewhere. Comparable instruments available internationally do not achieve the same accuracy or stability (zero drift characteristics with SPRT measurements are not obtainable in any other instrument), other instruments do not support the same variety of sensors, and offer considerably less operational features. The microK family uses solid state construction with no potentiometers or relays which ensures long term reliability and low cost of ownership, a feature of growing international importance.

In April 2017 Isotech won a Queens Award for Enterprise in the Innovation category for the co-development of the microK, read more in our news section.
