Isotech MicroK 2 High-Accuracy Thermometry Bridge

The Isotech MicroK 2 is an advanced thermometry bridge that offers unparalleled precision and reliability for temperature measurement in laboratory and industrial environments. Built on the success of the original MicroK models, the second generation is equipped with new features, including an additional input channel and an improved touchscreen, increasing versatility and usability.

Exceptional accuracy and stability

The MicroK 2 offers a resistance ratio of 0.03 ppm and an equivalent temperature measurement accuracy of only 7.5 μK at the water triple point. Thanks to a unique substitution topology, the device eliminates drift and thus the need for regular calibration or software corrections. Performance remains consistent even after long-term use, making the MicroK 2 cost-effective and minimizing maintenance.

New features and improvements

With the introduction of a fourth input channel, users can now simultaneously connect different sensors such as SPRTs, PRTs, Thermocouples, thermistors and reference resistors. This combination makes the MicroK2 unique considering that all common temperature sensors can be connected.
The redesigned 10.1-inch touchscreen offers an intuitive, high-resolution interface, allowing easy adjustment of settings and clear display of data. Connectivity has been expanded to include Ethernet, USB, RS232 and IEEE 488 (GPIB), facilitating integration into modern laboratory setups.

Measurement versatility

The MicroK 2 supports a wide range of sensors and measurement modes:

> Thermocouples: Very low uncertainties with a voltage accuracy of 0.15 μV.
> Cryogenic measurements: Supports measurements up to 4 K with RhFe thermometers.
> Zero-current resistance measurements: Automatic calculations reduce errors and increase accuracy.
> Keep-warm current: Prevents temperature fluctuations at connected sensors, even during prolonged operation.

Advanced technology and innovation

Thanks to parallel analog processing and a new sigma-delta ADC, the MicroK 2 minimizes voltage noise, reducing measurement uncertainty without sacrificing speed. This makes the device ideal for demanding applications, such as calibrations and measurements in national metrology institutes.

Applications

The MicroK 2 is perfect for:

> Temperature calibration: For primary and secondary laboratories.
> Cryogenic applications: Precision at extremely low temperatures.
> Industrial measurement setups: Compatibility with various sensor standards.
> Scientific research: Measurements with extremely low uncertainties.
