Series 600 Digital Temperature Loggers are most advanced microprocessor-based, digital thermometers designed to use external J-, K-, T-, and E-type thermocouples (temperature probes) as temperature sensors. Series 600 Thermometers with fast response and laboratory accuracy (0.1 % + 0.5 °C) have logging and PC interface capabilities. The powerful Windows® compatible software is optionally provided. Convenient closed case easy calibration (EasyCal) allows adjustments to be made directly by using the menu keys. The thermocouple(s) with wire spool(s) can be stored in the back of the thermometer. The 645 has quadruple inputs.
