How do I get an accurate RH reading from a Thermohygrometer?

Thermo-hygrometers are useful and accurate tools for measuring relative humidity (RH) in concrete slabs as well as RH and temperature for hardwood floor installation environmental conditions. The importance of rugged performance and rugged thermal hygrometer readings to maintaining the integrity of any construction project cannot be overemphasized. Fortunately, for building professionals who use thermal hygrometers, there are some easy ways to keep those meters in good working order for years to come.

proper care

Perhaps more than any other factor, getting accurate RH readings involves proper thermo-hygrometer care, aged sensor care, proper calibration, and protection from external chemicals or materials are necessary to maintain accurate meter performance.

There are many common structural elements that can damage a thermo-hygrometer and disrupt calibration, including PVC, acetate, and polystyrene. The rugged protective cover minimizes the possibility of contaminants, chemicals and dirt that can damage the gauge sensors. Extreme chemical exposure can permanently damage a thermo-hygrometer within hours and affect the meter's sensitivity by interacting with the sensor's polymer material.

Maintaining the calibration of your meter is very important to get consistent and accurate RH readings. Performing simple maintenance can go a long way in maintaining accurate meter calibration, such as:

• proper storage and stable environment.

• Test the sensor with a saline solution to verify calibration.

• Place a secondary reference sensor to compare readings on sensors used in the field.

Maintaining and verifying the calibration of your thermo-hygrometers is critical to success, as proper meter calibration can make or break an entire construction and restoration job.

Effective use, proper maintenance and calibration monitoring can keep your RH readings accurate and ensure your meter is operating efficiently for future use and success.

The Critical Role of Accurate Readings

Proper care and maintenance of your thermo-hygrometer can help ensure accurate readings that are so critical in many construction jobs. Inaccurate or faulty RH readings can void floor, paint and adhesive manufacturer warranties and stop operations for a significant amount of valuable time. By keeping the accuracy of their thermal hygrometers consistent and correct, construction professionals can avoid the hassle of voiding warranties and contractual obligations and keep their projects moving forward.

Knowing how to make a durable thermo-hygrometer operate effectively requires an effective understanding of how these tools work. Understanding the sensing components of a thermo-hygrometer, and how to set up and maintain a proper calibration, is a logical first step in getting the most out of your thermo-hygrometer.
