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.

LF55 Series pressure switches are usually used with fluorinated refrigerants to control the pressure of compressor in refrigeration system. It can also used in air and water. Air compressor switch for pressure control. Internal Micro-swith ensures reliable switching. It is provided standard Mounting Bracket. Temperature package available.

LEFOO LFM5 series differential pressure transmitters are widely used for air or neutral gas detection. This differential pressure transducer adopts imported micro-pressure core, digital pressure acquisition, and temperature compensation, and has the characteristics of sensitive pressure response, stable long-term output, and superior temperature performance.

It has 0.5% FS accuracy, can OEM, strong overload capability, multiple pressure ranges and signal output, easy installation, ROHS certification, CE certification, strong electromagnetic interference resistance, wide range measurement, etc. This differential pressure transducer is widely used in HVAC, energy management systems, VAV and fan control, cleanroom pressure, smoke hood control, oven pressurization, furnace ventilation control, and other fields.

LFB series is widely used for measuring the fans or blowers pressure, filter resistant, wind speed, furnace gas pressure, Orifice pressure difference, bubble level and hydraulic system pressure. It is also applied to regulate the air-gas combustion ratio and automatic valve or detecting the breathing, and blood pressure in medical equipment. There are some more applications like microelectronics, aviation and space, environmental protection project, biological engineering, intelligent building, HVAC, food and beverage and precision electronic processing

The LF32 is an adjustable differential pressure switch capable of detecting miniscule changes in pressure do to its size and proven design. The air pressure switch set point or switching point can be field adjustable with out the need of a manometer by simply using the adjustment knob and the built in calibrated visual scale. This air flow switch is equip with a clear cover that not only protects the adjustment knob to be move involuntary but also provides class IP54 protection.
