AP105 high-precision intelligent digital pressure gauge is specially designed for high-end supporting customers with high standards. The digital pressure gauge uses ultra-high-precision and stable pressure sensors. AP105 intelligent digital pressure gauge is a high-precision low-power intelligent pressure measuring instrument.

AP105 uses a 105mm dial 55x55mm ultra-large LCD screen, and the frequency division display of the main screen and the sub-screen at the same time, while displaying real-time pressure, can simultaneously display site temperature, maximum pressure, minimum pressure and other reference data. The digital pressure gauge has many functions such as zero reset, backlight, power on / off, unit switching, low voltage alarm, etc. The digital pressure gauge is easy to operate and install. Currently passed CE, CPA, Ex-explosion, RoHS certifications.

AP105 is a high-precision pressure gauge with on-site temperature and pressure measurement and display. The digital pressure gauge has the characteristics of anti-vibration, high display accuracy, high stability, zeroing, and automatic standby. The digital pressure gauge is preset 10 common pressure units to choose from, with adjustable pressure collection rate, displayed battery power. The digital pressure gauge is also equipped with USB external power supply and battery dual power supply mode, powered by 3 AA batteries, using ultra-low Power consumption design, can last more than 3600 hours. Adopting high-precision ADC and high-speed microprocessor, all digital design, high precision, good stability and beautiful appearance. With automatic standby and one-button reset function, easy to use, suitable for pressure measurement fields such as portable pressure measurement, equipment matching, calibration equipment, etc.
