Description
The TES-3142 / TES-3142U Pitot Tube Anemometer & Differential Pressure Manometer is a versatile, high-precision instrument designed for professional airflow, pressure, and environmental measurements in HVAC, industrial, and laboratory applications. It features a triple-display 4-digit LCD that simultaneously shows multiple parameters, including differential pressure, air velocity, temperature, and relative humidity. Using a Pitot tube, the instrument accurately measures air velocity from 1 to 80 m/s and differential pressure from −0.8 to 0.8 psi, enabling reliable calculation of volumetric flow rates based on duct size. With fast response times and a warm-up time of less than one minute, it delivers quick and stable readings in real-world conditions.
Beyond basic airflow measurements, the TES-3142 series provides advanced environmental calculations such as dew point, wet bulb temperature, wind chill, heat index, and humidity index, making it a comprehensive diagnostic tool. Users can record instantaneous, average, and maximum values, supported by data hold and max/min/avg functions. The TES-3142U model adds enhanced data management with microSD card logging and USB connectivity for automatic data storage and software-based analysis. Powered by four AA batteries with up to 70 hours of operation, and supplied with essential accessories including a Pitot tube, hoses, and carrying case, the TES-3142 / 3142U combines accuracy, portability, and robust functionality for demanding field measurements.
