CPD2/20 precision digital barometer

CPD2/20 precision digital barometerIt is a portable precision digital barometer. This barometer can measure both the air pressure on site (with a resolution of 0.01hPa) and the relative pressure difference at various points on site (with a resolution of 1Pa). This barometer has reliable vibration resistance, and the errors caused by normal impacts and vibrations during transportation can be ignored. This barometer can measure temperature and eliminate drift caused by temperature changes. This barometer uses LCD display to measure data and measurement time, and can store 100 sets of test data. The barometer is equipped with a printer, and users can print out the measured data on the ground. The rechargeable battery inside the barometer can provide continuous operation for 24 hours. This barometer is lightweight and easy to carry, making it an ideal testing barometer.
