The Tisch 1-canister Sampler takes air from the inlet on the pump and injects it into the canisters at a constant flow rate for a preset time. The excess air is released through the bypass exhaust. The constant flow rate and elapsed time allow the operator to compute the volume of the integrated air samples. The samples are pumped through a Stainless Steel, Teflon diaphragm, 12 V.D.C. pump, which develop sufficient pressure to control the flow with a Porter regulator. The pump also samples the air at a flow rate (5 L/min) to keep any long sampling line flushed. A small, constant flow of sampled air is pumped into the sample canisters. The sampler will operate on 12 volts d. c. through a molex plug on back of sampler. The pointed end of the plug is positive (+) and the flat end is negative (-), and draws 5 amps. (ALWAYS USE A 5 AMP FUSE INLINE ON THIS 12V.D.C. INPUT) The a/c cord will take an input of 100-240 V.A.C. at 2 amps.
