Product Description

The TPI 326 is a pocket-sized digital thermometer with a replaceable probe tip that extends instrument service life. Measuring -58°F to 300°F (-50°C to 150°C) with ±1°C accuracy, the 326 handles HVAC/R refrigerant line temperature checks, aircraft cabin temperature surveys, and general-purpose maintenance. The replaceable probe means a damaged or worn tip does not require instrument replacement — just a new probe, reducing total cost of ownership. Compact enough for a shirt pocket or tool pouch.
