Contronics has been a Pioneer in the measurement and control of humidity using electronic sensing .Humidity can be measured using dry / wet sensors .Conventional mercury thermometers are replaced by electronic sensors and a wet wick with water reservoir is used .Capacitive sensors for humidity measurement do not require a water wick. Where direct water is not being sprayed and humidity is less than 95% dry sensors are i convenient to use and are reasonably accurate .Humidity is a measure of moisture content in air and an important parameter in computer rooms, greenhouses ,grain storage, pharmaceutical industries, wood ,cloth manufacturing paper ,leather industry and a host of other industries. Moisture is also responsible for rusting and measuring & control of humidity is imperative. High moisture causes grain to rot. Lot of exotic plants and flowers are grown in controlled humidity and temperature conditions.Countronics humidity indicators with automatic control function ensure reliable growth of plants. Automotive industry monitors humidity to ensure components do not rust. Food and beverage industry like wine, coffee and tea leaves processing have to necessarily control humidity in the atmosphere. For medical applications also ,controlled humid air is used for even patients on ventilators .All said and done, humidity control results in a lot of savings and avoids great financial loss .Countronics make humidity/ temperature monitoring and logging is available for or all the above applications.
