Temperature / Relative Humidity / Infrared

Temperature and Relative Humidity sensors are available as standalone instrumentation or as accessories on other meters. These sensors, along with other features can be found on indoor air quality meters, ventilation test equipment, particle counters or any equipment where it is useful to have this type of data. Proper temperature and Relative Humidity are important to the survey data and may have an influence on the meter it is added to.



-  Temperature Range:  11 degrees to 140 degrees Fahrenheit

-  Relative Humidity Range: 10% to 90%


Temperature and Relative Humidity Calibration at CIH Equipment

We can calibrate in our Thermotron SM1.2 environmental chamber, known as one of the most stable chambers developed. We also have a variety of means for relative humidity such as the Michell S503 and Blue M chamber. We use the finest standards for comparisons that are both accurate and repeatable, like Vaisala and Instrulab Relative Humidity and Temperature standards. We can calibrate heat stress monitors, indoor air quality meters, ventilation test equipment, and a variety of probes.


Heat Stress Monitors are compared against our reference standards at set temperature and relative humidity points. Our procedures are designed to maximize the accuracy, repeatability, and reproducibility of your temperature and relative humidity measuring instruments. A Certificate of Instrument Calibration is issued if the heat stress monitor, along with all three of its sensors (wet bulb, dry bulb, and globe temperature), have passed calibration.


CIH Equipment Company is an A2LA accredited ISO 17025:2017 laboratory. We use NIST traceable standards and calibrate to manufacturers specifications and ANSI standards.
