UEI TEST INSTRUMENTS

About UEI TEST INSTRUMENTS

UEi Test Instruments is a manufacturer of handheld and benchtop test and measurement instruments for the HVAC/R, electrical, and foodservice trades. The company's product line includes digital multimeters, clamp meters, combustion analyzers, refrigerant leak detectors, vacuum gauges, air velocity meters, and temperature instruments. UEi products are used by technicians and engineers for diagnosing and maintaining refrigeration systems, air handling units, electrical circuits, and commercial kitchen equipment. The brand is known for offering practical, field-ready instruments with clear displays and rugged construction. 3G Electric supplies UEi Test Instruments products globally, with a catalog that includes 37 SKUs covering clamp meters, thermometers, leak detectors, and other test tools. Among the available items are the WVG2 series digital vacuum gauges, such as the DMG150, which measure vacuum levels from 0 to 15,000 micron Hg with an accuracy of ±5% or ±5 micron. The HUB8 series wireless refrigeration diagnostic kit (MPN HUB8) combines pressure, temperature, humidity, and dew point measurement with a wireless vacuum gauge probe, and is compatible with the UEi HUB app. For air velocity and environmental measurements, the DAFM4 hot wire air velocity meter measures air velocity, CFM, dew point, and relative humidity, with a digital display and battery power. Temperature instruments include the NSF-rated digital pocket thermometers, such as the 550B, PDT550-N, PDT660-N, PDT550, and PDT660, which cover a range of -58°F to 572°F (-50°C to 300°C) with 0.1°F/0.1°C resolution and accuracy of ±1.8°F/1°C from -22°F to 302°F (-30°C to 150°C) and ±4°F/2°C outside that range. These thermometers are NSF-rated, making them suitable for food safety applications. 3G Electric supports the UEi line by stocking these instruments and providing specification details, part numbers, and quote-based procurement for buyers worldwide. The catalog includes multiple part numbers within the same product family, allowing selection based on specific measurement ranges, accuracies, and features. For technical buyers, UEi instruments offer defined measurement specifications, battery-powered operation, and in some cases wireless connectivity for remote monitoring. The product range addresses common tasks in HVAC/R diagnostics, electrical testing, and foodservice temperature verification. 3G Electric's role is to make these instruments available to industrial and commercial customers, with the ability to source specific models and provide documentation as needed. The focus is on supplying the correct instrument for the application, backed by clear specifications and part number identification.
