CETATEST 915 Flow Tester
The CETATEST 915 is a precision flow tester for measuring air flow using compressed air. It uses a laminar flow element (LFE) and differential pressure sensor to deliver direct or indirect flow tests. With multiple LFEs, it supports very wide flow ranges, intuitive controls, and optional electronic pressure regulation.

CETATEST 915 Flow Tester
The CETATEST 915 delivers reliable, repeatable measurements thanks to its 24-bit ADC, multiple LFEs, and filter/regulator options. Users can choose between direct or indirect methods, set up test phases (filling, stabilising, venting), and view flow in ml/min, ml/h, l/min, or l/h. Accurate to 2 % of full scale.
