Relative Humidity – Calibration

Veronics Instruments Inc. is standing by to meet your calibration needs for all of the Relative Humidity Measuring devices we supply. From in house calibration to a stream line process for returning goods to the GE Industrial Sensing, to the Supply of Equipment that enables you to have a state of the art calibration facility in your laboratory. Feel free to contact us for all of your calibration requirements.

Calibration Systems

The GEIS product line offers a range of systems providing the ability to verify, calibrate and document humidity sensors used in applications in aerospace, automotive, pharmaceutical, electronic, plastics, chemical, food processing/storage and HVAC (Heating Ventilation and Air-Conditioning Controls). Our state-of-the-art systems are highly reliable, easy to install, easy to use, and easy to maintain.


HumiTrace is the market-leading system for reliable and precise calibration of virtually any relativity humidity probe. Each HumiTrace humidity calibration standard is supplied with an INAB calibration certificate. This not only ensures that your instrumentation readings are accurate and that your product conforms to the specification, but that it also satisfies the requirements of your QA system and any accreditation you have.
