EE371 is dedicated for accurate and reliable monitoring of the dew point temperature (Td) in the range -60...60 °C Td (-76...140 °F Td), with pressure rating up to 100 bar (1 450 psi). It is ideal for compressed air systems and industrial process control. Besides Td, the device measures also frost point temperature (Tf) or volume concentration (Wv).
The EE371 features the innovative, monolithic E+E HMC01 humidity and temperature sensing element. In combination with a sophisticated auto-calibration procedure, this leads to accuracy better than ±2°C Td (±3.6 °F Td) and to excellent long term stability.
The robust metal enclosure, the swirling front-end, various process connections and sampling options allow for easy and comfortable design-in, mounting and operation. The measured data is available on two freely configurable voltage or current outputs as well as on the LCD display.
An optional adapter and the free EE-PCS Product Configuration Software facilitate easy configuration and adjustment of the EE371.

What is the difference between dew point temperature and frost point temperature?
The dew point temperature (Td) indicates where condensation begins. The frost point temperature (Td) indicates where icing begins.
Is the E+E dew point probe / sensing element wettable?
Yes, the probe and the sensing element of all E+E dew point measurement devices is wettable.
Which E+E products are appropriate for low dew point measurement?
Low dew point means the difference between the ambient temperature and the dew point temperature is higher than 40 °C (72 °F). This corresponds to RH < 5%.
The appropriate products are the EE371 and EE355. Both devices feature an auto-calibration procedure.
What is the auto-calibration function at the E+E dew point measurement devices good for?
The auto-calibration corrects periodically even the smallest drift of the capacitive sensor at very low relative humidity. This is neccessary 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.
Which E+E dew point measurement devices feature auto-calibration?
Auto-calibration is used by EE371 and EE355.
What calibration certificate is included in the standard scope of supply of the E+E dew point sensors?
The standard scope of supply of E+E dew point sensors includes an inspection certificate according DIN EN 10204 - 3.1. For details on calibration certificates please see page 5 in www.kalibrierdienst.at/fileadmin/content/White_Paper_Calibration_and_traceability_in_measuring_technology.pdf
Can E+E supply an accredited calibration certificate with the Dew point sensor?
Accredited calibration certificate for CO2 is available upon request, please see our calibration website.
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.
