EXTECH
EXTECH is a brand of test and measurement instruments widely used in industrial maintenance, HVAC, electrical, and facility management applications. The product line includes multimeters, tachometers, refractometers, hygro-thermometers, refrigerant leak detectors, anemometers, psychrometers, and light meters, among others. EXTECH instruments are designed for field service, plant engineering, and quality control environments where portable, battery-powered measurement tools are required. Typical specifications include RPM accuracy of ±0.05% to ±0.1%, Brix accuracy of ±0.2%, and air velocity resolution down to 1 fpm. Many models feature data logging, LCD displays, and onboard sensors. The brand is known for offering a range of analog and digital instruments with varying levels of precision, from basic handheld units to more specialized devices like heated diode refrigerant leak detectors compatible with A2L refrigerants such as R-513A. EXTECH instruments are generally supplied without calibration certificates unless specified, though some models include NIST-traceable certification. 3G Electric stocks over 380 EXTECH SKUs, covering categories such as contact and non-contact tachometers, analog refractometers, data logging temperature and humidity meters, refrigerant leak detectors, vane anemometers, psychrometers, and light meters. These instruments are used for measuring rotational speed, surface speed, Brix concentration, ambient temperature, dew point, relative humidity, refrigerant leaks, air velocity, and light levels. The product range supports applications in HVAC system diagnostics, industrial machinery maintenance, food and beverage quality testing, and environmental monitoring. EXTECH instruments are built to standard industrial tolerances and are typically powered by replaceable batteries. The brand does not emphasize proprietary connectivity or software ecosystems; instead, it focuses on standalone functionality with clear analog or digital readouts. 3G Electric provides global logistics for EXTECH products, enabling procurement for plant engineers, maintenance managers, and procurement specialists worldwide. The selection includes models with and without NIST calibration certificates, allowing buyers to match instrument accuracy requirements with their specific quality assurance protocols.
