Humidity calibration with a high-end humidity calibrator

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.

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

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 evel has not been reached yet. The display should stop blinking after about 3 minutes when reached the new RH point. For a longer (or continuously) blinking display please consult the HUMOR20 operation manual.

The cover is part from the measuring chamber and is mandatory for an accurate calibration with the HUMOR20. Please consult E+E if a cover for your needs is already available.

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

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

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

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.

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

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

During normal operation mode, incease the humidity generated by the Humor 10 to the maximum by rotating the blue knob counter-clockwise. The HUMOR 20 display will show arround 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.

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 festure 3 calibration points (15/55/90%RH) or 5 calibration points (15/35/55/75/90%RH). Other certificates upon request.

Transmitter with "two-wires" technology receive the power from the process, and the signal is carry on return wire (closed current loop). With technology "three-wires" the power supply is separate from current output: 2 wires are the power supply and third carry the signal.
