Carbon dioxide gas transmitter Kwiksense

carbon monoxidesulfur dioxideoxygen

Product Overview
The Uniphos KwikSense Smart Digital Gas Transmitter is a universal field-mounted gas transmitter for detection and continuous monitoring of a wide range of toxic and flammable gases in industrial processes. It supports Uniphos Smart Gas Sensors with pre-calibrated, swappable sensor modules and transportable calibration for rapid sensor replacement. Non-intrusive calibration and configuration are performed using a magnetic wand to minimise downtime. The transmitter provides industry-standard 4-20 mA analog output and RS-485 MODBUS-RTU digital communication; HART protocol is available as an option. The unit holds multiple international certifications including ATEX, IECEx, MED and SIL2.
