Hand-Held Calibrator for Leak Testers.A new hand-held instrument is said to quickly and accurately calibrate To adjust or bring into balance. Scanners, CRTs and similar peripherals may require periodic adjustment. Unlike digital devices, the electronic components within these analog devices may change from their original specification. See color calibration and tweak. most makes of pressure-, flow-, or vacuum-type leak testers. Offered by InterTech Development Co. (IDC), Skokie, Ill., model CM-25 CalMaster is designed for smaller leak rates and lower-flow applications. It has a calibration calibration /cal·i·bra·tion/ (kal?i-bra´shun) determination of the accuracy of an instrument, usually by measurement of its variation from a standard, to ascertain necessary correction factors. range of 0.025 to 1.999 sccm (standard cc per minute). IDC offers the CM-15 for higher flow ranges. CalMaster calibrators provide a direct and almost instantaneous reading of leak rates with repeatability of 0.05% and traceable to NIST (National Institute of Standards & Technology, Washington, DC, www.nist.gov) The standards-defining agency of the U.S. government, formerly the National Bureau of Standards. It is one of three agencies that fall under the Technology Administration (www.technology. primary standards. Volumetric volumetric /vol·u·met·ric/ (vol?u-met´rik) pertaining to or accompanied by measurement in volumes. vol·u·met·ric adj. Of or relating to measurement by volume. measurements are displayed on an LCD. These compact units are just 7.5 x 4.3 x 3.125 in. and weigh 1.8 lb. They accept maximum test pressures to 250 psig and maximum test vacuum to 5 psig. |
