The Humor 20 scope of supply includes an inspection certificate according to DIN EN 10204 – 3.1 in the standard scope of supply. An accredited calibration certificate with specific test points is available upon request.

Please mention that you require an accredited calibration certificate when inquiring for a new Humor 20 or when returning for service or re-calibration an existing Humor 20. The most common accredited certificate feature 3 calibration points (15/55/90 %RH) or 5 calibration points (15/35/55/75/90 %RH). Other certificates upon request.

During normal operation mode, increase the humidity generated by the Humor 20 to the maximum by rotating the blue knob counter-clockwise. The Humor 20 display will show around 100% RH, flashing. Open the cover of the distilled water tank and remove the cover from the calibration chamber. If the display shows is 100 %RH ±0.8 %RH, the Humor 20 is within specifications. Is the reading is beyond 100 %RH ±0.8 %RH please see the operation manual, chapter 6.4.

This is the sensing head from the plausibility sensor from the Humor 20.

By design, the temperature inside the measuring and the saturation chamber of the Humor 20 is uniform. By this, in the range 10 to 40 °C the influence of the ambient temperature is negligible.

With distilled water inside during transportation, the Humor 20 may be tilted max. 20°. If this cannot be assured, the water must be removed before transportation.

The humidity generator requires a compressed air of max. 10 bar (145 psi), filtered from particles > 0.1 µm , with residual oil <0.01 mg/m³

The humidity generator requires distilled water. Do not ever fill in tap water, because it causes deposits in the piping and pressure regulators, which leads to malfunction and eventually to the failure of the Humor 20.

When you plan to use the humidity generator again within the next 4 days we recommend to keep it powered and the humidity level set to 100 %Rh. For longer periods out of use, please remove the water and dry the humidity generator before switching off the power.

Set the display switch to temperature.

A blinking display after rotationg the blue knob for setting a new RH level indicates that the new RH level has not been reached yet. The display should stop blinking after about 3 minutes when the new RH point is reached. For a longer (or continuously) blinking display please consult the Humor 20 operation manual.

Yes. Please contact E+E for details and availability.

The cover is part of the measuring chamber and is mandatory for an accurate calibration with the Humor 20. Please consult E+E to check if a cover for your needs is already available.
