Gas Mass Flow Controller

Description

Max-Trak Model 180 measures and controls gas mass flow rates from 0 to 200 slpm (optionally to 400 slpm) with accuracy of ±1% FS and repeatability of ±0.2% FS. Flow body is slightly longer than 5 in. Controller meets the rigorous requirements of NEMA 6 and IP67, making it ideal for washdown environments.
