Calibration determines that the fl ow rate of air through the pump is accurate, within specifi ed limits, usually ± 5%. A primary calibra-tion device, the DigiCal™ Calibrator provides instantaneous calibration for instruments like the Zefon Escort LC Pump or the secondary fl ow standard inside the Escort ELF Sampling Pumps.Just press the plunger and the DigiCal Calibrator does the work. Its unique fl ow cell replaces conventional bubble tubes and makes calibration easier. The DigiCal Calibrator achieves extreme accuracy by utilizing a computerized fl ow meter that provides instantaneous fl ow readouts on a digital display. Accurate measurements are possible within ±0.5% at any altitude. Gemini® Twin-Port SamplerFor low-fl ow control when sorbent tubes are used, the patented Gemini Twin-Port Sampler is a valved mecha-nism that allows fl ow adjustment down to 1 mlpm (0.001 lpm to 600 mlpm total between both tubes). U.S. Patent No. 5,370,004. As an added benefi t, the Gemini accessory permits simultaneous sampling from sorbent tubes, with independently controlled fl ow rates of each. Dual sampling means two like sorbent tubes can be attached for simultaneious sampling at differeent fl ow rates, or two different tubes can be used to sample two types of substances at once.Escort® Pump AccessoriesEscort, Gemini and DigiCal are trademarks of Zefon International.
