High Accuracy Temperature Probes
Connect directly to any XR440 or XR5-SE Data Logger. All probes utilize a precision 30k ohm thermistor with 0.1 deg. C interchangeability.
PT900 Series Temperature Probes
Connect up to eight probes to the XR5-SE Data Logger, and up to four probes to the XR440 Data Logger.
Common to all PT900 series Probes
- 0.1°C Interchangeability
- Resolution 0.02°C at 25°C
- No calibration required
- Probe cables may be extended using ordinary copper wire.

Extension Cable
Extension cable can be spliced to any of the above probes. We recommend 24 gauge two-conductor stranded copper cable for extensions of up to 100 feet (30 meters). For longer extensions, 22 gauge cable is recommended. Acceptable splicing methods include wire nuts, crimp connectors, hand twisting and taping, or solder. For cable runs longer than 30 feet, we recommend using shielded cable (Belden 9501 or equivalent).
