The E2618-H2S concentration sensor is a member of the new range of multifunctional measuring instruments PluraSens®. It is designed for industrial applications where it is necessary to monitor the presence of hydrogen sulfide (H₂S) in the air. The device uses a fully calibrated and temperature-compensated electrochemical sensor with high accuracy, fast response, and long lifespan.

The E2618 series sensors represent an intelligent solution for modern measurement and regulation systems with Modbus RS485 communication and two analogue outputs 4–20 mA / 0–10 V. Thanks to their robust design with IP65 protection, they are suitable for demanding operations, laboratories, or industrial spaces.

The sensor is available in versions:

wall-mounted version
wall-mounted with remote probe
for piping

With measuring range:

0...100 ppm H₂S (standard version)
other ranges on request

The device can be supplied with or without a display LCD screen.

The sensor is sensitive to gas:

Hydrogen sulfide (H₂S)

THE DETECTOR IS STANDARDLY CALIBRATED TO 100 ppm H₂S.

Each sensor is factory calibrated and ready for immediate use. The recommended recalibration interval is 6 months. The lifespan of the electrochemical sensor is approximately 2–3 years depending on operating conditions. Calibration can only be performed by a person certified by the manufacturer.

Do not hesitate to contact us for recalibration!
