Started in 2005 with three partners well established in Technical & Techno Commercial field, we are manufacturing Measuring instruments, Sensor Transmitter, Sunpro Measuring Instruments, Precision Measuring Instruments, Chart Recorder, Pressure Sensor, Meteorological Sensors, Air Velocity Transmitter, Weather station, Digital Data Logger. The results of measuring the air velocity can be stored in memory of the device depending on the model. Description: The Series 471 Digital Thermo Anemometers are versatile dual function instruments that quickly and easily measure air velocity in four field selectable ranges, in either feet per minute or meters per second, plus air temperature in °F or °C. The DegreeC product portfolio includes air velocity, temperature, and humidity sensors, analytics & data logging software, air visualization instruments, and airflow controllers, alarms and monitors. An E+E air velocity sensor consists of two resistors deposited on a thin glass substrate. Together with FLOXACT™ measurement probes the same devices are the right option when measuring flow in a duct. Up to 3 probes can be connected simultaneously: a Bluetooth probe, a wired probe and a temperature probe with type K thermocouple connector. New Portable Air Velocity Meter The industrial-grade Series 2440 Thermal Anemometer is an accurate & reliable instrument for industrial hygiene, HVAC, and other general applications.

However, anemometers are also critical instruments for applications such as balancing forced hot air HVAC systems, the analysis of ventilation. Transcat is your premier provider of air flow measurement. Temperature Process Instruments, TPI 556C1 Digital Air Velocity/Air Flow Vane Thermo-Anemometer Meter, Measure Air Velocity and Temperature Simultaneously. ISO calibration certificate. Since most field instruments do not measure Q directly, it is necessary to determine Q by taking a series of velocity (V) measurements at some point in the system , determining an average velocity and then multiplying this average velocity by the cross sectional area (A) of the opening through which the air is moving at the location where the. [8] Air Velocity Plot Digital Display [9] Air Temperature/Velocity Plot Legend [10] Export Plot: Push to export the Air Velocity Plot to a BMP file. Industrial Measuring Instruments We are one of the leading manufacturers, supplier and exporters of industrial measuring instruments which includes velocity meters, scientific velocity meters,industrial velocity meters etc. Anemometers are also used to measure wind speed and indoor airflow.
