• The instrument uses three hole probe (patent) to measure flow pressure, deflection angle and near axis velocity of airflow vector in flue or pipe;
• The instrument adopts microcomputer program control, automatic data processing, Chinese prompt, simple and convenient operation;
• The deflection component of airflow is displayed in real time, and the measurement of low velocity is more accurate;
• High precision sensor, multi-point calibration algorithm, high accuracy;
• Both AC and DC.

Th-210 two-dimensional pitot tube adopts three hole probe, which is mainly used for accurate measurement of air flow deflection angle and near axis velocity in various pipeline gas pipelines, especially for low flow velocity pipeline; and automatically measures the air flow direction and the angle between pitot tube, prompting real-time correction and more accurate measurement.
