For optimal use of the data logging features of the instrument, the DewCheck DC7520 Docking station and DewCheck DC7510 USB data cable are available. The DewCheck dock is indispensable for communication between Dewcheck device and computer
3 strong Neodymium magnets hold instrument and dock firmly against ferrous steel surfaces. Magnets are lined with rubber to prevent damaging the surface and sliding of the unit.
A magnetic surface temperature sensor overrides the instrument’s integrated surface temperature sensor in order to guarantee correct TS-readings.
USB-Interface connects the unit to the PC for programming and downloading data.
2-Year Warranty that covers everything except physical damage.
