Request a quoteThe ACR-201 and ACR-203 are the brass dial-a-flow regulators for calibration gas, for sites that calibrate several detectors at different flow rates and want one regulator rather than a drawer of fixed ones. A top mounted dial selects from twelve preset positions across one of three ranges chosen at order: 0 to 8 litres per minute, 0 to 3 litres per minute in finer steps, or 0 to 15 litres per minute, with the first position on each dial being off. The two models differ at the inlet. The ACR-201 takes the 5/8 inch by 18 UN C10 cylinder thread at up to 83 bar with a brass gauge to 103 bar, and the ACR-203 is the high pressure version with a 1/4 inch NPT female inlet rated to 207 bar and a gauge to 220 bar. Both have a 3/16 inch barb outlet, a brass piston, PTFE, Viton and Buna-N seals and an anodised aluminium bonnet, and both are for non-reactive gases. They weigh 0.35 and 0.40 kg.
