Product Overview:

       The Mass Flow Meter (TSI 4140) is suitable for various gas flow measurement applications. Whether measuring airflow in laboratories or manufacturing workshops, TSI's universal mass flow meter provides accurate measurement results. With extremely low pressure drop, it minimizes network backpressure and its impact on the system, making it ideal for daily calibration requiring precision. It is widely used in laboratories, medical fields, and industrial applications.

Product Features

1. Compact and lightweight, ready to use;
