Testo 512-2 Digital Manometer/Anemometer Kit, 0 to 200 hPa Pressure, 10 to 100 m/s Velocity, 0 to 60° C Temperature

The Testo 512-2 digital manometer and anemometer with Pitot tube measures air pressure in hPa, Pa, kPa, inH2O, inHg, mmH2O, mmHg, and psi; air velocity in m/s and fpm, and air temperature in degrees C and F; and has hold, maximum, minimum, and damping functions for analyzing air flow. Hold function freezes a reading on the display, maximum and minimum functions display the highest and lowest readings since the meter was powered on, and damping function displays the mean value of up to 20 readings. A built-in infrared interface transmits measurement data to a Testo printer (sold separately). The LCD shows two measurement parameters simultaneously and a backlight provides visibility in low light. The unit has an auto-off mode that shuts it down after 10 minutes of non-use to conserve battery life and has a low-battery indicator. This instrument is used for performing diagnostic measurements such as total external static pressure, differential pressure, manifold pressure, and duct velocity of HVAC (heating, ventilation, and air conditioning) systems, among other applications.

Specifications

H is height, the vertical distance from the lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.

Anemometers, also called wind meters, measure air velocity and are most commonly used for weather monitoring to determine wind speed and for HVAC applications to determine air flow within ducts. In addition to air velocity, anemometers may measure wind direction, air pressure, air flow volume, air temperature, humidity, light, and other properties. The most common types of anemometer are cup, vane, hot-wire, and Pitot tube. Cup and vane anemometers calculate air velocity based on the number of rotations of the cups or vane. Hot-wire anemometers calculate air velocity by measuring the change in electrical resistance as air flow cools a heated wire. Pitot tube anemometers measure air pressure within a tube and calculate air velocity based on the difference in pressure between the air inside and outside of the tube. Many anemometers have digital readouts and can display air velocity readings in different units of measure, such as meters per second (m/s), feet per minute (ft./min. or fpm), knots, miles per hour (mph), and kilometers per hour (km/h).
