Cpd2 / 20 precision baromete

Product introduction of cpd2 / 20 precision barometer , Cpd2 / 20 precision barometer is a portable instrument specially designed and developed for mine ventilation test
Cpd2 / 20 precision barometer can measure both local pressure value and pressure difference between two points
Precision barometer has the characteristics of high precision, high sensitivity, reliable structure and essence
The whole instrument is light, easy to carry, not afraid of general vibration and collision, and has stable and reliable performance
It is an ideal underground ventilation test instrument
The explosion-proof sign is exib I (150 ℃) mine intrinsic safety type
