AP80 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. The digital pressure gauge is a high-precision low-power intelligent pressure measuring instrument.

AP80 is equipped with a large-size LCD liquid crystal display with Dial 80mm. The digital pressure gauge has various functions such as zero reset, backlight, power on / off, unit switching, low-voltage alarm, etc. It is easy to operate and easy to install. Support optional timing acquisition data storage, support USB data export, can store up to 10,000 pieces of data. Currently passed CE, CPA, Ex explosion and RoHS certifications.

AP80 is a high-precision pressure gauge with integrated pressure measurement and display. The digital pressure gauge has the characteristics of anti-vibration, high display accuracy, high stability, clearable, and automatic standby. Powered by battery. Due to the low-power processor chip, it has a long battery life. With automatic standby and one-click reset functions. The digital pressure gauge is easy to use and can replace mechanical pressure gauges for portable pressure measurement, equipment matching, and standard pressure calibration. Inspection equipment and other fields.
