Uei Test Instruments PDT550 Waterproof Digital Thermometer

Product Description

The UEI TEST INSTRUMENTS PDT550 is a waterproof digital thermometer built for field use by HVAC technicians, plumbers, and other trade professionals who need fast, accurate temperature readings in wet or harsh environments. It covers a wide measurement range of -58 to 572 degrees F (-50 to 300 degrees C), making it suitable for a broad set of diagnostic and service tasks. The plastic housing is designed to withstand job-site conditions, and the built-in magnetic mount keeps the tool hands-free when attached to equipment panels or metal surfaces. MIN/MAX record function allows technicians to capture temperature extremes without continuous monitoring.

The PDT550 is suited for residential and light commercial HVAC service, plumbing diagnostics, refrigeration work, and general mechanical service applications. Its compact form factor - 0.91 inches wide, 1.26 inches deep, and 7.24 inches long - fits easily in a tool bag or belt pouch. The waterproof rating makes it practical for use near condensate systems, outdoor equipment, and other moisture-prone environments where standard instruments may fail.

Installation Notes

The PDT550 is a handheld diagnostic instrument and does not require permanent installation. Technicians should ensure the probe and housing are fully dry before storage to maintain the waterproof seal over time. When measuring temperatures on energized equipment, follow applicable NFPA 70E electrical safety practices and avoid contact between the probe and live electrical components unless the instrument is rated for that use.
