Description

LEFOO LFG60 All-in-One Air Quality Transmitter is used to detect a variety of air quality parameters, including temperature and humidity, CO2, PM2.5, PM10, VOC, formaldehyde, up to 7 parameters; optional isolated/non-isolated RS485 output, built-in Modbus protocol, realize real-time detection of multi-point distribution data. indoor type can be equipped with display screen and keys, and the split screen can display air quality parameters.

By configure communication parameters, the three-color LED indicator can be equipped to directly indicate the air quality situation. both indoor type and top suction type can configure RS485 communication address through dialing code. The product has wide power supply range and perfect overvoltage and reverse connection protection; it can be widely used in multi-parameter air quality monitoring in various commercial complexes, intelligent building, office environment hotels, airports and schools.
