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, incease the humidity generated by the Humor 20 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.
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.
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.
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.
Set the display switch to temperature.
Yes. Please contact E+E for details and availability.
Calibration means comparing the specimen with a reference and documenting the deviations. Adjustment means bringing the specimen in line with the reference.
Both certificates state the deviation of the speciment from the reference, while the accredited certificate also includes the overall uncertainity of the calibration process. Only an accredited calibration certificate is traceable to the national standard (NMI) and international standards. See also our white paper "Calibration and Traceability in measuring technology".
There is no difference. The E+E factory calibration certificate is an ISO certificate.
Before returning a device for service or calibration, please contact E+E, an E+E subsidiary, or an E+E distributor for a quote and instruction on the return procedure.
Yes, this is possible in most of the cases. Before sending in a device for calibration, please contact E+E, an E+E subsidiary, or an E+E distributor, which will confirm if the required calibration can be performed and issue a quote.
The E+E calibration laboratory performs accredited calibrations for: relative humidity, dew point temperature, air velocity, flow, temperature, CO₂, and pressure. For details please see our calibration website for details of possible ranges of calibration.
Transmitter with "two-wire" technology receive the power from the process, and the signal is carried on return wire (closed current loop). With "three-wires" technology the power supply is separate from current output: 2 wires are the power supply and the third carries the signal.
Do not attempt to clean the filter cap. This would only lead to its clogging. A dirty filter cap must be replaced by a new, original one. See the accessory data sheet for replacement filter caps.
The E+E proprietary sensor coating is a protective layer applied to the active surface and leads of the sensing elements. The coating extends the lifetime and the measurement performance of the E+E sensor.
The E+E propritary coating helps in dirty, dusty and corrosive environments. (salts, off-shore applications). It improves the sensor’s long-term stability in dusty, dirty or oily applications by preventing stray impedances caused by deposits on the active sensor surface and on its connecting leads.
The E+E propriatary coating oating does not help against chemicals in gazeous form. Contact an E+E sales representative for details on the influence of certain chemicals onto the humidity sensing elements.
The response time of a humidity sensor protected by the E+E proprietary coating is slightly longer than the response time without coating. Please see the data sheet of the specific sensor.
Temperature gradients along the sensing probes lead to relevant measurement errors. Whenever possible, install the entire probe inside the space that is to be monitored. If the probe is installed into a separation wall, make sure to thermally isolate the part of the probe thaht is looking out of the wall at the cable side.
The product data sheet indicates if and what type of inspection certificate is included in to the standard scope of supply. Most of the E+E measurement devices feature an inspection certificate according to DIN EN 10204-3.1 or DIN EN 10204-2.2. An accredited calibration certificate is available on request, see the E+E scope of accreditation at our calibration website.
The calibration / adjustement interval depends on the application and on the requirements of the specific industry. See also "Princibles of Humidity measurement".
Calibration for a specific oil is a laboratory procedure for determining the saturation curve of the oil. The saturation curve is described by two parameters (A and B). These parameters are used for setting up the moisture in oil sensor for correct calculation of the water content (ppm) out of the measured temperature and water activity (aw).
Sensor replacement is possible for the EE360 models with the ordering code including PC4 (pluggable probe). Please see the operation manual for detail and spare part code ordering guide.

The dew point temperature (Td) indicates where condensation begins. The frost point temperature (Tf) indicates where icing begins.
Yes, the probe and the sensing element of all E+E dew point measurement devices are wettable.
Low dew point means the difference between the ambient temperature and the dew point temperature is higher than 40 °C (104 °F). This corresponds to RH <5%.
The appropriate products are the EE371 and EE355. Both devices feature an auto-calibration procedure.
High dew point means the difference between the ambient temperature and the dew point temperature is lower than 3 °C. It corresponds to RH >85%.
The appropriate product is the EE33-M4T7. The device features a heated sensing element.
The auto-calibration corrects periodically even the smallest drift of the capacitive sensor at very low relative humidity. This is necessary for high accuracy and long-term stability of the dew point measurement. The auto-calibration is performed every 30 minutes and takes approx. 3 minutes. During the auto-calibration, the output is frozen at the last measured dewpoint value.
Auto-calibration is used by EE371 and EE355.
