The Detcon TP-700 by Teledyne is a non-intrusive, “Smart” sensor designed to detect and monitor H2S in the air over a 0-100 ppm range, utilising proprietary solid-state metal oxide semiconductor technology. The plug-in, field-replaceable detector features oversized gold-plated connections that help prevent corrosion.

The TP-700’s rugged framework features an electro-polished 316 stainless steel housing, fully encapsulated electronics, and dual-layer surge protection. This innovative design eliminates sensor failure due to water ingress, corrosion, vibration, and transient spikes. A primary feature 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 TP-700 has standard analogue 4-20mA and Modbus RS-485 outputs. Its unique feature 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 solid-state MOS H2S gas sensor has an infinite shelf life and a 10-year conditional warranty.

Applications include oil and Gas drilling and production sites, Refining and Petrochemical facilities, Pulp and Paper Mills, and Wastewater Treatment Plants.
