Alicat MCW Series Low Pressure Drop Controllers

Performance

Available ranges: max 0-1000 slpm, min 0-0.5 sccm/0-500 sμlm

Steady state control range: 0.01% – 100% of full scale.

Standard accuracy calibration, NIST-traceable: +/- (0.8% of the reading + 0.2% of the full-scale range)

Optional high-accuracy calibration, NIST-traceable: +/- (0.4% of the reading + 0.2% of the full-scale range)

Repeatability: 0.2% of the full-scale range

Typical control response time constant: 50-100 ms (as low as 25 ms with PID tuning)

No warm-up time required

Operating Conditions

Compatible gaseS: 98 pre-loaded selectable gas calibrations; additional mixtures definable with COMPOSER

Operating temperature: -10°C to +60°C

Max internal pressure (static): 45 psig (60 psia)

Proof pressure: 175 psig (190 psia)

STP/NTP: user-selectable (defaults to 25°C & 1 atm STP/0°C & 1 atm NTP)
