For demanding fixed gas detection systems that require Intrinsic Safety (Ex ia), Instrusense India recommends the highly versatile Dräger Polytron 7000. This advanced gas transmitter is engineered for the continuous measurement of a vast range of Toxic Gases (CO, H₂S, $\text{NH}_3$, $\text{Cl}_2$, etc.) and Oxygen ($\text{O}_2$) using smart, long-life Dräger electrochemical (EC) sensors with integrated data memory.Operating on a simple 2-wire 4-20 mA loop, the Polytron 7000 significantly reduces installation costs. It is highly user-friendly, featuring an easy-to-use menu structure with real-text messages and a large, backlit display for clear reading of gas concentrations. The device is verified to SIL 2 level, providing high resistance to electromagnetic interference and ensuring maximum functional safety. Its optional features, like the integrated pump module for sample drawing (non-hazardous areas) or the relay module for standalone system operation, offer maximum flexibility for various Indian industrial applications. The robust GRP (Glass Fiber Reinforced Plastic) housing ensures durability and a high level of environmental protection.
