JH-YBS-WY-type vacuum pressure calibrator is of Jiangsu Cable Co., Ltd. Jinhua instrument in the production and development of new test instrumentation, its cost performance is superior to similar products in the company's UK Druck, vacuum pressure calibrator not only solves the standard pressure calibration, and better meet on-site comprehensive testing needs. 
 JH-YBS-WY-type vacuum pressure calibrator basic accuracy of 0.1% and 0.05% sub-two, is the laboratories, factories, universities ideal tool for high-end table, and serve as the standard medium-accuracy pressure test table is pressure gauge, pressure gauge, pressure transmitter, pressure switch, pressure gauge, vacuum gauge, and so the ideal calibration instruments. 
 ● Features 
 1, JH-YBS-WY-type vacuum pressure calibrator for the AC-DC dual-use portable instrument, the measurement of pressure, measure current, while the LCD display, and with 24VDC output. Coupled with vacuum pressure calibrator front panel fitted with pressure hand pump, making it ideal for on-site calibration instruments. 
 2, high-performance microprocessor for instrument zero and linear continuous correction to ensure zero instrument for a long time with good accuracy and repeatability and stability of the measurement accuracy. 
 3, the calibrator has the over-range alarm function, when applied pressure exceeds the rated full scale +2500 words, the meter will display OVER RANGE! P, and built-in buzzer will sound intermittently to indicate the pressure (current) exceeds full scale, should stop pressure, and relieved some of the pressure to within the specified range, to avoid damage to the pressure sensor. 
 4, when the calibrator measured when the current exceeds 22mA meter will display OVER RANGE! I and the built-in buzzer will sound intermittently to indicate the measured current over-range. 
 5, calibrator software content-rich, simple and clear. 
 6, the thin-film touch panel and start the import, fashionable, key long life. 
 7, LCD backlight, the pressure, the current display, intuitive, clear, compact structure. Pressure calibrator small size, light weight, easy to carry. 
 8, calibrator front panel mounted manual operator pressure generator,-90KPa ~ 1.6MPa, with a fine-tuning, put the valve. Manual vacuum rate of 95%, with the world advanced level. Source of stress components by fine grinding, good gas tightness, IP54-rated sealing. 
 9, can operate directly on the panel, adjust the full scale. 
 10, metal, interference is strong, strong resistance to stamping. 
 11, displacement fine-tuning, easy to achieve the test point pressure.
