Overview
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 proprietary solid state metal oxide semiconductor technology. Features plug-in, field replaceable detector with over-sized gold-plated connections, electropolished 316 stainless steel housing, fully encapsulated electronics, and dual layer surge protection. Equipped with standard analog 4-20mA and Modbus RS-485 outputs, wireless option compatible with SmartWireless product line, and optional Remote Alarm Module (RAM) and HART integration. Includes embedded intuitive software with built-in alpha/numeric display for calibration, configuration, and fault diagnostics. Solid state MOS sensor with infinite shelf life and 10-year conditional warranty. Explosion proof rated (Class I, Division 1, Groups B, C, D; ATEX II 2 G Ex d IIB + H2 T4 Gb). SIL2 certified. Available with optional Aluminum or 316 SS Junction Box.
