    Extech 42275 Temperature/Humidity Datalogger Kit with PC Interface

    Capable of recording up to 16,000 readings, the Extech 42275 Temperature/Humidity Datalogger Kit is perfect for use in most environments, including shipping vans, storage containers, freezers, warehouses, industrial refrigeration units and cargo ships.

    Featuring a user-programmable sampling rate of 1 second to 2 hours, in addition to Hi/Lo limits with alarm indication, the Extech 42275 has a wide operating temperature range of -40 to 85°C (-40 to 185°F) and a humidity range of 0 to 100% RH, making it a very versatile instrument.

    Temperature and humidity are shown on a clear LCD screen and the built-in clock stores date and time info with the data. With three start methods (scheduled, immediate and magnetic), the Extech 42275 can log data for days, weeks or even months, boasting a battery life that can last up to one year.

    The PC interface allows users to program the logger whilst analysing and storing data using Windows 95 / 98 / 2000 / NT / ME / XP compatible software, with the RS-232 docking station allowing data to be streamed instantly onto a PC.

    Please Note: The datalogger unit will not function without the docking station and PC software.
