Connect directly to any XR440 Data Logger input channel. All probes utilize a precision 30k ohm thermistor with 0.1 deg. C interchangeability. Up to four temperature probes can be connected to one XR440 Data Logger. For temperatures up to 260°C, a Platinum RTD Probe is available. For thermocouples, plug-in Thermocouple Modules are available.

PT510 / PT520 Platinum RTD Temperature Sensors
Price: PT520: $67. (260 degree C / 500 degree F max. temp.)
PT510: $46. (200 degree C / 392 degree F max. temp.)
User's can easily splice extension cable to any of the above probes. We recommend using copper 24 gauge two-conductor stranded cable for cable extensions of up to 100 ft. (30 meters). For longer extensions, use 22 gauge two-conductor stranded cable. Acceptable methods of splicing sensor leads to extension cable include wire nuts, crimp connectors, hand twisting and taping, or solder. For cable runs longer than 20 feet, we recommend using shielded cable (Belden 9501 or equivalent).
