Humor 20

Humidity calibration with a high-end humidity calibrator

Questions about our products?

The Humor 20 humidity calibrator is a high-end portable reference device traceable to international standards.

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 supply 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.

  • Can I rent / lease / lease-buy a HUMOR20?

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

  • How can I see the temperature inside the calibration chamber of the HUMOR20?

    Set the display switch to temperature

  • The display of my HUMOR20 blinks. Is this normal?

    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.

  • Can I use my own made cover for the measuring chamber in order to increase the volume of the chamber?

    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.

  • Should I switch of the HUMOR20 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.

  • Can I fill tap water into the HUMOR20?

    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.

  • Which compressed air supply is appropriate for the HUMOR20?

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

  • What precautions shall I observe when using the HUMOR 20 calibration throughout the manufacturing plant?

    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.

  • 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.

  • 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.

  • 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.

  • How can I get accredited calibration 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.

  • What is the difference between a 2 wire and a 3 wire current output?

    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.
