UEI TEST INSTRUMENTS

UEI Test Instruments, founded in 1964 and headquartered in Beaverton, Oregon, USA, is a manufacturer of portable electronic test and measurement equipment for HVAC/R, electrical, and building performance professionals. The brand is known for producing rugged, field-ready instruments that prioritize accuracy, ease of use, and durability in demanding environments. 3G Electric supplies a range of UEI Test Instruments products, including air velocity meters (rotating vane and hot wire anemometers), thermocouple thermometers and probes, psychrometers, refrigerant diagnostic kits, and sensor replacement caps. These instruments are designed for applications such as HVAC system balancing, combustion analysis, refrigeration diagnostics, and temperature measurement in industrial and commercial settings. Key technical specifications across the product line include NIST-traceable calibration certificates, temperature accuracy of ±1.0°F or better, relative humidity accuracy of ±3%, and measurement ranges from -328°F to 2,498°F for thermocouple meters. Air velocity meters offer resolutions as fine as 0.01 km/h (rotating vane) or 0.1 fpm (hot wire), with some models measuring CFM and dew point. The HUB8 wireless refrigerant probe kit integrates pressure, temperature, humidity, and dew point sensing with app compatibility for data logging and analysis. UEI instruments typically feature digital displays, battery power, and carrying cases for portability. 3G Electric stocks over 37 SKUs from UEI Test Instruments, providing procurement specialists and maintenance managers with access to a broad selection of meters and probes for field service, plant maintenance, and commissioning tasks. The product range supports both standard and specialized measurement needs, from basic temperature checks to comprehensive HVAC system diagnostics.

Frequently asked questions

Common questions about UEI TEST INSTRUMENTS from 3G Electric.

What types of air velocity meters does UEI Test Instruments offer?

UEI Test Instruments offers both rotating vane and hot wire anemometers. Rotating vane models, such as the DTHA2 and DTHA2-N, measure air velocity with a resolution of 0.01 km/h and include relative humidity and temperature sensing. Hot wire models, like the DAFM4, provide a resolution of 0.1 fpm and can measure CFM and dew point. Both types are battery-powered and include digital displays.

Are UEI Test Instruments thermocouple probes compatible with other brands?

UEI Test Instruments thermocouple probes, such as the ATT39 Type K surface temperature probe, use standard Type K thermocouple connectors. This makes them compatible with any meter that accepts Type K inputs, including meters from other manufacturers. The ATT39 has a temperature range of -40°F to 950°F and a fluoroplastic-coated cable.

Does the UEI HUB8 refrigerant probe kit require a smartphone for operation?

The UEI HUB8 smart refrigerant probe kit is designed to work with the UEi HUB app, which runs on smartphones or tablets. The kit includes a wireless vacuum gauge probe and measures pressure, temperature, humidity, and dew point. The app provides data display, logging, and analysis capabilities. The probes communicate wirelessly, so a compatible device is required for full functionality.

What calibration options are available for UEI Test Instruments meters?

Many UEI Test Instruments meters, such as the DTHA2-N rotating vane anemometer, are available with NIST-traceable calibration certificates. This ensures the instrument meets specified accuracy standards. For models that do not include a certificate, calibration services may be available through third-party providers. Check the specific SKU for calibration certificate type.

Can UEI Test Instruments psychrometers measure both temperature and humidity?

Yes, UEI Test Instruments psychrometers, like the DTH35, measure both temperature and relative humidity. The DTH35 has a temperature range of -4°F to 122°F and is an onboard psychrometer with a compact form factor (9.38 in x 1.63 in x 0.63 in). It is suitable for HVAC applications requiring simultaneous temperature and humidity readings.

Does 3G Electric supply UEI TEST INSTRUMENTS products?
