Humor 20 humidity calibrator with EE10
The Humor 20 generates relative humidity in the range 10-95 % RH and can accomdate probes diameter 8-25.5 mm (0.3-1″) as well as data loggers or room mount humidity sensors.
Humor 20 operates on the fundamental dual-pressure reactor principle similar to the references used in national bureaus for standards. It can be employed both as laboratory and portable humidity generator and reference. For operation Humor 20 requires only distilled water, clean oil-free air with a pressure of 10 bar (145 psi) and a power supply between 90-230 V AC.

FAQ
What kind of calibration certificate is included in the standard scope of the HUMOR 20?
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.
Hocan can I get accredited certificate for the HUMOR 20?
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.
How can I easily test if my HUMOR 20 performs within specs?
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.
I can see inside the measuring camber of the HUMOR 20 the sensing head of an RH sensor. What is it used for?
This is the sensing head from the plausibility sensor from the HUMOR 20.
What is the temperature influence onto the HUMOR 20 humidity generator?
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.
What precautions shall I observe when using the HUMOR 20 humidity generator?
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.
Which compressed air supply is appropriate for the HUMOR 20?
The humidity generator requires a compressed airof max. 10 bar (145psi), filtered from particles > 0.1µm , with residual oil <0.01mg/m³
Can I fill tap water into HUMOR 20?
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.
Should I switch the HUMOR 20 in my laboratory when not in use in order to save energy and distilled water?
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.
How can I see the temperature inside the calibration chamber of the HUMOR 20?
Set the display switch to temperature
The display of my HUMOR 20 blinks. Is this normal?
A blinking display after rotating 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.
Can I rent / lease / lease-buy a HUMOR 20?
Yes. Please contact E+E for details and availability.
