The constantly increasing requirements on measurement technology demand the integration of new technologies with regard to electronics hardware, interfaces and software for accurate measurements in metal applications.

Checkmate IV

Instrument for checking system accuracy of thermocouple, millivolt and thermal analysis instruments. A portable unit which allows for use on the shop floor.


Quick and accurate measure of hydrogen content of molten metal on the operating floor.

  • Hydris - Direct reading immersion system

iM2 Sensor Lab

Molten metal measurement system capable of handling all sensors. Two station, wired or wireless capable with touch screen monitor.



To ensure the quality of molten steel, its temperature and chemical composition must be constantly monitored. Immersion sensors take precise measurements of these parameters and relay their results within seconds.

Fast, accurate, and reliable liquid metal temperature readings are indispensable tools for cost-effective temperature control during steel production.


Accurate and dependable, expendable immersion lances for molten metal temperature measurement.

Available In: small and large diameter.

Oxygen Probes

Celox probes are designed to measure oxygen levels from 1 ppm to 2500 ppm. With the emphasis on clean steel production, the oxygen activity measurement has become a valuable tool in monitoring steel quality.

Available In: high level, low level and small diameter.

Immersion Sampler

Provides a smooth surface and homogeneous sample.

Available In: disc only, disc and pin, and dual thickness.


Time saving, instant analysis provides information on carbon content, bath temperature, liquids temperature with a single immersion.




Newest wireless solution for steelmaking. No extension wire from pole to wall. Robust design with internal antenna, long battery life and advanced analog frontend filtering out noise & protecting circuit boards resulting in more stable/accurate temperature and oxygen readings.

  • Compatible with existing iM2 and Metnet systems

Hardware and Accessories

Custom preassembled pole arrangements to suit customer requirements. Contact blocks, lance holders, compensated cable, connectors and preassembled cables for in house rebuild programs.
