Detcon Model TP-700 is a non-intrusive “Smart” sensor designed to detect and monitor H2S in air over the range of 0-100 ppm using a proprietary solid state metal oxide semiconductor technology. The plug-in, field replaceable detector features over-sized gold-plated connections that help prevent corrosion.
The TP-700’s rugged framework includes an 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 TP-700 is embedded intuitive software that simplifies 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 is equipped with standard analog 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), HART, and Foundation Fieldbus. Detcon’s solid state MOS H2S gas sensor has an infinite shelf life and is supported by a 10-year conditional warranty
