Are Your Meter Readings Accurate?
You count on your thermo-hygrometer to provide you with accurate information. But errors do crop up, and here’s why they might be happening:
- Insufficient acclimation time. This acclimation time can range from 2–15 minutes, depending on the model used and conditions of the air stream.
- Weak battery
- Soiled or damaged probe
- Operator’s breath or perspiration
- Proximity of air currents (e.g., HVAC, dehumidifiers, airmovers, etc.)
- Specification limits of the probe being used (many do not read below 20% relative humidity)
Since thermo-hygrometer readings are used to make psychrometric evaluations and demonstrate that equipment is really working, make sure your readings are accurate.
