 JH-YBS-WY Vacuum Pressure Calibrator instrument is of Jiangsu Cable Co., Ltd. Jinhua engaged in the production and development of new test instruments, the cost performance is superior to similar products in the United Kingdom Druck company, not only the vacuum pressure to solve the standard calibrator pressure check, and to better meet the comprehensive test-site needs. 
 JH-YBS-WY-type vacuum pressure calibrator basic accuracy of 0.1% and 0.05% sub-two, is the laboratories, factories, universities form the ideal high-end tools, and accuracy of stress testing as a secondary standard tables, is pressure gauge, pressure gauge, pressure transmitter, pressure switch, vacuum gauge, and so the ideal pressure instrument calibration instruments. 
 ● Features 
 1, JH-YBS-WY-type vacuum pressure calibrator for the AC-DC dual-use portable instrument, the measurement of pressure, measurable current, and displayed on the LCD, and with 24VDC output. Coupled with vacuum pressure calibrator front panel fitted with hand pumps suppressed, making it ideal for on-site calibration instruments. 
 2, high-performance microprocessors for instrument zero and continuous linear correction to ensure zero instrument for a long time and accuracy with good repeatability and stability, measurement accuracy. 
 3 calibrator with over-range alarm function, when the pressure increases beyond the nominal full-scale +2500 words, the meter will display OVER RANGE! P, and built-in buzzer will sound intermittently to indicate the pressure (current) than full range, stop pressure, and relieved some pressure to within the specified range, so as not to damage the pressure sensor. 
 4, when measured calibrator than 22mA of current when the instrument will display OVER RANGE! I and built-in buzzer will sound intermittently to indicate the current over the measured range. 
 5, calibrator, software, content-rich, simple and clear. 
 6, membrane touch panel and the beginning of import, fashionable key long life. 
 7, LCD backlight, the pressure, current display, intuitive, clear, compact and reasonable. Pressure calibrator small size, light weight, easy to carry. 
 8, calibrator front panel to install the terminal pressure generator,-90KPa ~ 1.6MPa, with a fine-tuning, put the valve. Manual vacuum was 95%, with the world advanced level. Source of stress components by fine grinding air tightness, meet IP54 sealing standards. 
 9, can be directly on the panel operation, adjustment of full scale. 
 10, metal shell, strong anti-interference, strong resistance to stamping. 
 11, displacement tuning, easy to implement test point pressure.
