High-precision CO transmitter with LCD display, configurable alarm relay, and optional analog or RS485 output. Ideal for HVAC, kitchens, workshops, and parking facilities.
Product Description
Specifications
This indoor carbon monoxide transmitter is built for accurate, real-time monitoring of CO levels in enclosed environments. Featuring a high-performance imported electrochemical sensor, it delivers fast response times, stable readings, and long-term reliability in a wide range of commercial and industrial applications.
The unit includes a backlit LCD display for clear local readouts and supports current, voltage, or RS485 (Modbus) output for seamless system integration. A configurable relay output enables independent control or alarm activation when CO levels exceed a set threshold—enhancing safety in high-risk areas.
With overvoltage and reverse polarity protection, a slim and modern housing design, and compatibility with standard 86 box installations, this transmitter is both practical and dependable. Ideal for use in HVAC systems, underground car parks, restaurant kitchens, workshops, and other enclosed spaces where carbon monoxide safety is essential.
