The Detcon DM-700-H2S by Teledyne is a non-intrusive “Smart” sensor designed to detect Hydrogen Sulfide in the air using electrochemical sensor technology.

The intelligent plug-in, field-replaceable cell automatically recognises the gas type and range and features oversized gold-plated connections that help prevent corrosion.

The Model 700’s rugged framework includes an intrinsically safe electro-polished 316 stainless steel housing with fully encapsulated electronics and dual-layer surge protection.

This innovative design virtually eliminates sensor failure due to water ingress, corrosion, vibration, and transient spikes.

A primary feature of the Model 700 is embedded intuitive software that simplifies the operator interface by guiding the user through routine calibration, configuration, and fault diagnostic functions using a built-in alpha/numeric display.

The Model 700 is equipped with standard analogue 4-20mA and Modbus RS-485 outputs. Among its unique features is a wireless option that can be used with Detcon’s SmartWireless product line. Additional integration options include a Remote Alarm Module (RAM) and HART.

Detcon’s H2S sensors have a long shelf life and an industry-leading warranty. Models for other toxic gases are available.

Applications: Oil & Gas, Chemical Plants, Food & Beverage, Steel Mills, Pulp and Paper, Refineries, Wastewater Treatment Plants and Utilities.
