MicroK Gold
microK GOLD - a unique package
Best performance, documented, guaranteed with an unmatched satisfaction promise.
The microK 70 and 125 models are designed for the Primary Temperature Laboratories whilst 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). In April 2017 Isotech won a Queen’s Award for Enterprise in the Innovation category for the co-development of the microK, read more in our news section.
When used with a 0°C 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 0.01°C with a Platinum / Gold Thermocouple at 1000°C.
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.

Confidence in Thermometry Bridges The microK range of thermometry bridges have rapidly established themselves as the number one choice for temperature metrologists. Many NMIs are now using the new drift free microK technology and sales have exceeded our initial expectations. Of course the microK is not the only thermometry bridge available, there are both older and newer designs of bridge and all claim advantages with performance or measuring method.
AC or DC Measurement In the past it was the case that AC Bridges operated with lower noise than DC bridges but the microK uses a new parallel processing technique to match or exceed that which previously needed impedance matching and the use of transformers.
Performance Different manufactures claim performance in different ways and it can be confusing to compare specifications. With the availability of the automatic resistance bridge calibrator more and more bridges are being calibrated with reports published, the microK is consistently shown to exceed its specification, which is not the case for all! Ask us for the latest reports.
Confidence With claim and counter claim we want to give you confidence and have introduced the microK GOLD package. With microK GOLD you get
We challenge you to find any other company to report ratio accuracy, measured with the RBC and who guarantee that for three years.
