The Alicat MCS & MCRS range of anti-corrosive mass flow controllers feature all 316L stainless steel wetted parts, suitable for aggressive gas applications where gases like NH3, SO2, H2S and SiH4 may be present.

The MCS mass flow controller is repeatable and accurate with calibrations up to +/- 0.4% of reading accuracy and every Whisper device has a 100:1 turndown ratio with flow rates starting from 2.5 microliters per minute up to 3000 SLPM.

The mass flow controller can be used as a standalone controller with the use of local display and push button keypad. The local display allows the user to see all flow data visible on one screen (mass flow, volumetric flow, absolute pressure, temperature) as well as control the flow or pressure of the gas.

RS-232 communications are standard as well as an analogue output signal such as 4 – 20 mA. A colour TFT display is an option.

Every Alicat device is backed by the manufactures limited life time warranty and ships with a NIST traceable calibration certificate.

Alicat MCS & MCRS whisper series mass flow controllers have a maximum operating pressure of 145 PSIG, with Atex certification available, the meter may be used in ATEX Class 1 Zone 2 environments. There is fully adjustable PID control valve tuning for best speed and stability whilst the MCS & MCRS can control mass flow, volumetric flow or absolute pressure with one device.

Other output options and communication protocols are also available.

CSA/ATEX area classification is optional. Ex nA IIC, T4 Tamb. -40°C ≤ Ta ≤ +50°C
