Extech SDL200 4-Channel Thermometer Datalogger

Extech logo

Four-channel data logging thermometer accepts both thermocouple and RTD probes. Data is recorded onto a standard SD memory card, instead of a built-in memory; the advantage being that when the memory is full the SD card can be simply changed out for unlimited data storage.

The removable SD card is easy to transport and insert into a computer’s memory card slot or SD card reader for upload. The data is provided in Excel, allowing you to easily analyze the information without the need for additional software. Data can also be streamed directly to a computer using the RS-232 port on the meter.

  • Records data onto an SD card in Excel® format for easy transfer to a PC for analysis
  • Data logging capability up to 20,000 records using a 2G SD card
  • User programmable sampling rate from 1 to 3600 seconds
  • Manual store and recall of up to 99 records
  • Records readings with real-time/date stamp
