Operation

Preparations for calibration with unsaturated salt solutions

• The sensor of the device to be tested and the calibration chamber must be clean and dry.
• If the protective grid of the sensor is clogged or dirty, it must be replaced with a new original protective grid before calibration.
• For an accurate calibration, the sensor to be calibrated, the calibration chamber and the salt solution must have the same temperature (calibration temperature), which must be kept constant during the entire calibration process.
• To achieve precise results, the calibration temperature must be 23 °C ± 2 °C. Ideally, calibration should take place in a temperature-controlled environment without any draught or direct sunlight.
• Information on the reference humidity value provided by a saturated salt solution at different temperatures can be found on the label inside the box of each set of ampoules.
• Do not hold the calibration chamber with your hand during calibration. This would lead to temperature fluctuations and incorrect calibration results.

Note
The calibration chamber must remain in a stable, horizontal position during the entire calibration process. The salt solution must not come into contact with the measuring head (tip of the sensor) of the device to be tested.

• Insert the sensor to be calibrated into the calibration chamber and check whether the set-up is stable. In some cases, it may not be sufficient to place the calibration chamber on a table. To ensure a stable set-up, it may be necessary to fix the calibration chamber and/or probe mechanically, as for example in case of heavy, long probes or wall-mounted / duct-mounted hygrometers with bulky enclosures.

Calibration

1. Place the calibration chamber horizontally or fix it in a horizontal position.

2. Remove the cover.

3. Place a textile pad on the bottom of the calibration chamber.

4. Choose an ampoule with the desired reference humidity, e. g. 35 % RH (HA010435).

5. Carefully shake and tap the glass to bring the fluid into the lower part of the ampoule.

6. dress back the tip of the ampoule at the mark to break it open.

7. Empty the content of the ampoule onto the textile pad by tapping it gently.

8. Insert the sensor into the calibration chamber until it reaches the opposite side. The measuring head (tip of the sensor) must not come into contact with the salt solution.
   Note
   Do not remove the protective grid.

9. Put the cover on the calibration chamber and close it tightly.

   • The hygrometer can now be calibrated or adjusted.
     We recommend the following stabilisation times for both calibration and adjustment:

   • 45 min for 0–65 % RH

   • 60 min for 80 % RH

   • 120 min for 95 % RH

For adjustment, please observe the instructions in the operating manual of the device to be tested.
Dispose of the textile pad after every calibration point. Rinse the calibration chamber with tap water and wipe it completely dry with a soft, lint-free cloth. Do not use any other solvents, sprays, alcohol-based cleaning agents or abrasive cleaners.
When calibrating several points, we recommend proceeding in a loop, starting with the lowest humidity, e.g. 10 % → 35 % → 50 % → 80 % → 50 % → 35 % → 10 %.

Available accessories

Disposal

The device does not contain any electrical or electronic elements. At the end of its life, please dispose of this device according to the valid legal requirements.
