Description: The model CWY122 digital pressure gauge is energy-saving, adopt internationally advanced measuring circuit, precise and reliable temperature compensation. It is also upgrading product of traditional pointer type pressure gauges. Applications: 1. Calibrate general pressure gauges, precision pressure gauges, other pressure gauges; 2. Precisely measure pressure value, analyse pressure changes, control pressure. 3. Use in laboratory and directly use on site. Specification: Measuring range: -95kPa50MPa ( optional within the range) Accuracy: 0.1%F.S , 0.05%F.S Dimensions: gauge head(Ï112mm 40mm),overall length(178mm) Weight: approx. 0.58 kg Pressure interface: M20 1.5, (user difined eg. NPT) Features: 1 5 digits, with backlight, which can be used in poor light conditions. 2 The gauge was tested temperature compensation,age, MAX/MIN values can be saved automatically. 3 High stability: low temperature drift, low time drift, strong anti-interference ability. 4 11 pressure units: mmH2O, mmHg, psi, kPa, MPa, Pa, mbar, bar, inH2O, inHg, kgf/cm2 etc. 5 Power supply: General 9V alkaline battery , or power supply adaptor to supply power . Sampling rate: The measuring rate can be user-defined to match the type of measurement required. If rate is 1 operation per second,the battery life is 2,000 hours; If rate is 1 operation per 10 seconds,the battery life is 8,000 hours; If rate is 8 operations per second,the battery life is 500 hours.
