Request a quoteThe ACR-202 and ACR-204 are the stainless steel dial-a-flow regulators for calibration gas, for reactive gases and for sites that prefer stainless throughout. 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 an off position on each dial. The ACR-202 takes the 5/8 inch by 18 UN C10 cylinder thread at up to 83 bar with a stainless steel gauge to 103 bar, and the ACR-204 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 stainless steel neck and piston, PTFE, Viton and Buna-N seals and an anodised aluminium bonnet. They weigh 0.38 and 0.43 kg.
