Product Specs

Our PR-25AP RTD Air Probe combines the availability of the high accuracy sensor options found in our Ultra-Precise RTD probes with the convenience and reliability of our M12 enabled PR-21 probes. The PR-25AP offers RTD accuracies of Class A, AA (formerly 1/3DIN) and 1/10DIN sensing elements with the ease and reliability of the M12 connection.

The PR-25AP RTD is also designed to provide a barrier to airflow between the air stream and the ambient conditions that has been tested to 400 psi with no leakage. The probe is constructed with a 316L stainless steel housing and sheath for strength and corrosion resistance. For ease of mounting, the PR-25AP is available with the following mounting thread options:

  • 1/2NPT
  • 3/8NPT
  • 1/4NPT
  • Non-Threaded Housing


  • The mounting thread options above allow the probes to be used in a wide variety of applications, including:
  • As stand-alone immersion sensors.
  • Installed directly into your product or process using an NPT threaded port.
  • The non-threaded design can be combined with our M12-Handle accessory to convert it for hand-held sensing applications.
  • Other applications using a variety of available compression fittings or other accessories.


  • The PR-25AP, like all of our M12 enabled probes, comes standard with a 4-wire, 4-pin, M12 A-Coded plug connector for easy assembly to extension cables. This allows it to be used in any 2, 3 or 4-wire measurement system for maximum flexibility. For 1/10DIN accuracy we highly recommend using a 4-wire measurement to take maximum advantage of the tight accuracy option.


    When ordering your PR-25AP sensor, don't forget your extension cable. Omega offers a wide selection of extension cables including over molded PVC, Polyurethane and Silicone cables, as well as customized cables in a variety of materials with optional stainless steel braid or hose for improved mechanical protection, and a wide selection of instrument connections.

    Connect your PR-25AP RTD sensor to one or more of Omega's wide variety of in-stock controllers, data loggers, transmitters, hand held thermometers, PLCs, or other measurement & control products to complete your measurement or control system. Omega offers a selection of programmable and fixed range transmitters that can be connected directly to the M12 connection of your PR-25AP sensor. There are also wireless transmitter options available.

    Is this temperature probe submersible into liquids?

    Asked by: Claire
    Thank you for your inquiry. This air probe is designed for measuring air only and cannot be submersed in liquids. We offer sealed probes that are designed for liquid submersion.
