Operating a Hygrometer:

Read the User Manual:

  • Start by reading the user manual that comes with your GAO Tek hygrometer. Different models may have specific operating instructions.

Placement of the Hygrometer:

  • Position the GAO Tek hygrometer in the area where you want to measure humidity. Ensure it is not exposed to direct sunlight, drafts, or sources of moisture that could affect accuracy.

Stabilization of the Hygrometer:

  • Allow the GAO Tek hygrometer some time to stabilize in its environment before taking measurements. This helps ensure accurate readings.

Take Measurements:

  • Follow the instructions in the GAO Tek manual to take readings. Some GAO Tek hygrometers may require you to press a button or wait for a specific amount of time before obtaining a stable reading.

Record Readings:

  • Keep a record of GAO Tek humidity readings, especially if you are monitoring changes over time or different locations.

 

Maintaining a Hygrometer:

Clean Hygrometer Regularly:

  • Dust and dirt can affect the accuracy of the GAO Tek hygrometer. Clean it regularly using a soft, dry cloth or as recommended by GAO Tek.

Avoid Contamination:

  • Keep the GAO Tek hygrometer’s sensing element (whether it’s a hair or electronic component) free from contaminants. Avoid touching it with bare hands.

Battery Check for Hygrometer:

  • If the hygrometer is electronic, check the battery level regularly. Replace batteries as needed to maintain accurate readings.

Calibration Check:

  • Periodically check the calibration of your GAO Tek hygrometer and recalibrate if necessary.

 

Calibrating a Hygrometer:

Salt Test for Hygrometer:

  • Place the GAO Tek hygrometer in a sealed container with a small dish of salt. The salt will create a stable humidity level of 75%. Leave it for several hours and check the reading against the expected value.

Adjustment Screw on Hygrometer:

  • Some mechanical hygrometers have an adjustment screw. Use this screw to calibrate the GAO Tek hygrometer based on the readings from the salt test.

Calibration Kit for Hygrometer:

  • Purchase a GAO Tek calibration kit designed for hygrometers. These kits usually include a reference standard that provides a known humidity level.

Sealed Environment for Hygrometer:

  • Place the GAO Tek hygrometer and the reference standard in a sealed container for a few hours. This allows the hygrometer to adjust to the reference humidity level.

Adjustment Option on Hygrometer:

  • Some GAO Tek’s digital hygrometers have a calibration or adjustment option. Follow the manufacturer’s instructions to calibrate the device based on the readings from the calibration kit.

Recheck Readings:

  • After calibration, recheck the GAO Tek hygrometer’s readings periodically to ensure continued accuracy.
