Product catalog summary

Overview
The EE371 is a compact dew point sensor designed for precise monitoring of dew point temperature (Td) ranging from -60 to +60 °C (-76 to 140 °F) with a pressure rating up to 100 bar (1,450 psi). It is suitable for compressed air systems and industrial process control, also measuring frost point temperature (Tf) and volume concentration (Wv).

Key Features

High Accuracy: Utilizes the E+E HMC200 sensing element with auto-calibration for accuracy better than ±2°C Td (±3.6 °F Td).
Outputs: Two configurable voltage or current outputs and an LCD display.
Design: Compact metal enclosure with various process connections and sampling options.
Configuration: Easy setup with optional adapter and free EE-PCS software.

Technical Specifications

Measurement Range: -60 to +60 °C Td (-76 to +140 °F Td).
Accuracy: ±2 °C Td (±3.6 °F Td).
Response Time: t90 <5 min for -5 to -50 °C Td, <20 s for -50 to -5 °C Td.
Volume Concentration: 20 to 200,000 ppm with accuracy of ±(5 ppm + 9% of measured value).

Calibration and Certification

Traceable Calibration: Accredited by Akkreditierung Austria, offering ISO 17025 certificates.
ISO 9001 Calibration: Provides comparative measurement against high-quality reference equipment.

Enclosure and Environmental Conditions

Material: Aluminium die-cast with IP65 protection.
Temperature Range: -40 to +70 °C for medium, -40 to +60 °C for electronics, -20 to +50 °C for display.

Sampling Cells
