DT4947SD 4 Channel Data Logger - Excel Format SD Memory Card

  • $249.00 USD

The DT4947SD 4-Channel Thermocouple Thermometer with Excel-formatted Data Logging SD Card is ideal for simultaneously monitoring up to four temperatures in a commercial or industrial setting—such as food or chemical processing, HVAC/R, power generation or paper production.  Be sure to order your temperate probes here.  This instrument does come with two bead type probes which are suitable for general applications but most users will want to order a probe that will work better for their specific applications.


  • Also measures the T1-T2 difference between any two channels
  • Works with and automatically temperature-compensates for six popular thermocouple types: "K", "J", "T", "E", "S" and "R"
  • Combining thermocouple types extends the overall measurement range to -148° to 3092°F (-100° to 1700°C)
  • The thermocouple port also accepts PT 100 Ω resistance-temperature detectors (RTDs); optional #RTDTP100 is available
  • Includes two #TPK500 thermocouple probes
  • Can automatically log four channels of data every day during same period (loop data recording)
  • Big (2.5 in. diagonal) front-panel green backlit LCD is easy to read
  • Min/Max memory + data hold
  • Sampling time is settable from one second to one hour
  • NIST calibration is available


  • Measurement range/accuracy of thermocouple port for thermocouples: -328° to 2498°F (-200° to 1370°C)/±(0.4% of reading + 2°F)
  • Measurement range/accuracy of thermocouple port for RTDs: -327° to 999°F (-200° to 537°C)/±(0.4% of reading + 1.8°F) from -327° to 999°F; ±(0.44% of reading + 1.8°F) from 1000° to 1562°F
  • Measurement range of included #TPK500 thermocouples: -50° to 500°F (-45° to 260°C)
  • Display size/type: 2.05 x 1.5 in. (52 x 38mm)/LCD
