HOBO® Thermocouple Family
These loggers accept standard Type J, K, and T thermocouple probes with plug-in subminiature connectors. Each logger includes cold-junction compensation, and two software-selectable measurement ranges for optimal resolution and accuracy. These loggers also have an internal temperature sensor which can be used to record ambient temperatures. Thermocouples are popular for their wide temperature range and specialized probes.

Features and specifications
  • Capacity: 32,530 measurements total
  • User-selectable sampling intervals: 0.5 seconds to 9 hours, recording times up to 1 year
  • Readout and relaunch with optional HOBO Shuttle
  • Drop-proof to 5'
  • Mounting kit included (hook/loop, magnet, and tape)
  • Programmable start time/date

  • Size/Weight: 2.4 x 1.9 x 0.8" (68 x 48 x 19 mm)/ approx. 0.9 oz. (26 gms)

Internal Temperature Sensor
This sensor is also used to measure the cold-junction temperature. The thermocouple readings are compensated in the logger regardless of whether this channel is selected.

  • Internal Range: 0°C to +50°C (+32°F to +122°F)
  • Internal Resolution: 0.4°C @ +21°C (0.7°F @ +70°F)
  • Internal Accuracy: ±0.7°C @ +21°C (±1.3°F @ +70°F)


Thermocouple Probes and Wires

All probes have standard subminiature thermocouple connectors and plug directly into HOBO Thermocouple Family loggers. The connectors are color-coded for type J (black), K (yellow), and T (blue) thermocouples according to the ANSI standard. Note that the accuracy specifications are for the probes only, and must be added to the logger's accuracy to determine the combined measurement accuracy.

Beaded Thermocouple Probes on Spool Caddies
These exposed-junction thermocouple probes include 6' of insulated 30-AWG wire wound on an integrated spool caddy/subminiature connector.
