Request a quoteThe CR-301 is a stainless steel vari-flow regulator for calibration gas, selecting the flow rate from a top mounted dial rather than delivering one fixed figure. Twelve dial positions cover 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 off. The inlet is the 5/8 inch by 18 UN C10 cylinder thread rated to 83 bar, with a stainless steel inlet gauge reading to 103 bar, and the outlet is a 3/16 inch barb for detector tubing. The body, neck and piston are stainless steel with PTFE, Viton and Buna-N seals and an anodised aluminium bonnet, and the stainless construction is for reactive gases. It weighs 0.46 kg.
