Air Temperature & Relative Humidity

Model MP-101

P/N: RT-101


The Model MP101 is a combined relative humidity and air temperature sensor designed for outdoor applications. Operation from a DC voltage with low power consumption with no warm-up time makes the MP101 particularly suitable for operation at remote locations. Energizing of the probe is required for only 0.25 seconds during each measurement The MP101 is provided with a naturally aspirated Solar Shield & Mount P/N RT-104-MPS. The MP101 can be used over long periods of time without any maintenance or recalibration.
