REED INSTRUMENTS R2450SD-RTD Pt100 Probe
The REED INSTRUMENTS R2450SD-RTD is a three-wire RTD temperature probe using a Pt100 (385) sensing element. It covers a measurement range from -58 Degrees to 752 Degrees F (-50 Degrees to 400 Degrees C). The transparent polyurethane cable extends 3 ft 2 in and terminates in a mini plug. It suits food service, industrial, commercial, medical, pharmaceutical, R&D and educational applications.
Mini-plug connection and three-wire wiring
Installation requires a compatible instrument that accepts a mini plug and supports three-wire RTD input. The polyurethane jacket resists oils and abrasion in harsh environments. A common error is connecting the probe to a two-wire input, which introduces lead-resistance error and degrades accuracy across the full temperature span. Ensure the meter or controller is configured for Pt100 (385) curve before use.
Stable output across -50 °C to 400 °C
The platinum element maintains a repeatable resistance-to-temperature relationship throughout the rated range without the drift seen in thermocouples during prolonged exposure. The three-wire construction cancels lead resistance so readings stay consistent during continuous logging sessions. The plastic handle remains cool enough for safe handling while the tip sits in process media at the upper limit.

Questions about this item
How do I verify the REED INSTRUMENTS R2450SD-RTD probe reads correctly after connecting it to my meter?
Connect the 3-wire mini plug to a compatible RTD input, then check that the displayed value matches a trusted reference thermometer at the same point; the Pt100 (385) element should track from -58 °F to 752 °F.
What comes with the probe and what must I supply separately?
The package includes the RTD probe with 3 ft 2 in polyurethane cable, plastic handle and 3-wire mini plug; you must provide a meter or controller that accepts a 3-wire Pt100 (385) input.
Which probe version should I choose for food-service use up to 400 °C?
This single model R2450SD-RTD covers -50 °C to 400 °C with a Pt100 (385) element, 3-wire mini plug and 3 ft 2 in cable, so it fits the stated food-service, industrial and lab ranges without further options.
