Meriam, LP2000I-10KIT, Portable Digital Manometer / Calibrator Kit w/ NIST CertMeri-Cal Portable Digital Manometer CalibratorKit price includes (1) Meri-cal Portable Meter (1) calibration, fitting kit ZA34386 (1) hand pump 961P (ZB34686) (1) test lead kit, ZA900529-00004 (1) AC charger ZB900615-00004 (1) carrying case ZA34491The Meri-Cal is a portable digital manometer/calibrator for Pressure and differential Pressure measurement. It features high accuracy and rugged design which brings laboratory test and calibration capability to the field. Meri-Cal's display simultaneously indicates Pressure (or differential Pressure) and electronic transducer/transmitter output in any of 8 key selectable engineering units. Meri-Cal continues to be the most cost effective and useful method of precise measurements. Meri-Cal is available with CSA certification for intrinsic safety for use in Class I,Groups A, B, C and D areas.FeaturesEngineering Units, In H2O at 20°C, cm H2O, PSI, in Hg at 0°C, mm Hg, Kg/cm2, kPa, mBar and user scaled. Rugged Design, The case is made of impact resistant, injection molded ABS material. The keyboard is a sealed membrane type having a chemical resistant polyester surface with tactile feedback type keys. Internal components have a protective conformal coating. Applications, The Meri-Cal may be used for test measurement of Pressure or differential Pressure and as a calibrator for mechanical recorders, gauges, pneumatic controls and electronic transducers and transmitters. Auto Zero, A push of a button automatically establishes zero. There is no need to compute compensation factors for local gravity, temperature or head difference due to the location of the tester versus the unit under test.
