Infra Control Systems (ICS) manufactures a full range of humidity-temperature indicators, controllers and transmitters for the accurate measurement and control of humidity (HVAC) using the most accepted proven technology. Innovative contamination-free sensors from Japan ensure high accuracy and maintenance-free long life. The company has recently procured state-of-the-art relative humidity generator for portable calibration purpose from USA, with traceability to NIST standards. Any sensor, circuit or substance that will fit in the test chamber can be exposed to a wide range of known humidities. Features of the humidity calibrator include the ability to communicate with peripheral devices via a standard RS-232C serial port. The instrument is designed to provide highly accurate calibration checks with amazing speed and reliability. If needed, complete humidity monitoring system can be provided, including sensors, transmitters, indicators, controllers and dataloggers, and PC based systems. The sensor is contamination-free bulk polymer sensor, with features like increased accuracy using temperature compensation, fast response, long life and high accuracy. Option for space mount or duct mounts are available on request. Application areas include: HVAC, environment chambers, product drying, pharmaceutical, photographic and other paper, textile industries, chemical plants, food-tobacco processing, fertilizer, sugar industries, floriculture, green houses, storage rooms, museums and control rooms of process plants.
