What Is the 21075A Compatible Adult General Temperature Probe?

The IPR Medical TS-PH-AG30 is a compatible aftermarket (not OEM) adult temperature probe that replaces OEM part 21075A. Its probe type is general (oral/rectal), it uses Dual-Pin 400 Series temperature technology, and it pairs a 0.16 in (4.0 mm) probe tip with a 9.8 ft (3.0 m) cable. It is designed for repeated use across many patients.

Compatible Monitor Models

Each monitor this adult probe is listed for has its own line in the Compatible Monitor Models table on the Specifications tab. The bulk of that list comes from the OEM of part 21075A, with the Welch Allyn Propaq CS and the Contec Patient Simulator MS400 included as well. Verify your model against the table before ordering.

Design and Construction

Sized for adult patients, the TS-PH-AG30 combines a 0.16 in (4.0 mm) general-purpose tip with Dual-Pin 400 Series temperature technology and 9.8 ft (3.0 m) of cable. Each probe is supplied one per bag and is designed to be reused. Clean and disinfect it between patients according to facility protocol, and inspect the tip and cable every time it comes back into service.

When to Replace Your Adult Oral/Rectal Temperature Probe

Replace the probe when its readings drift, settle slowly, or disagree with a reference thermometer, or when the monitor reports no probe even though one is connected. Physical warning signs include a damaged or loose tip, a cut or cracked cable jacket, and bent pins at the connector. A probe that still reads poorly after a side-by-side check with a known-good probe on the same monitor should come out of service.

Cross Reference and Interchange Part Numbers

Besides OEM part 21075A, purchasing records may identify this probe by OEM number 989803203561 or 989803100881. The Specifications tab breaks out every interchange number by brand under Cross Reference / Interchange Part Numbers.
