2 Channel Temperature and Relative Humidty Data Logger

The MCS 486TRH is a low cost data logger for the measurement of air temperature and relative humidity. It can be programmed to record averaged, minimum and maximum temperatures and RH at a set recording rate. Thanks to the micro-power design it can run unattended for one to two years from a single Lithium Battery, depending on the recording rate.

The data logger is protected from extreme climatic conditions in it's splash proof PVC housing. All that is needed is to protect the sensor from direct solar radiation to record true air temperature profiles. Suitable shields are available from MC Systems.

This logger is well suited to record data in orchards and vineyards. Other applications include temperature stability monitoring in cooler transportation container vehicles.

Windows 95/98/NT4/2000 software to download the recorded values and display a chart is supplied with the data logger.
