Đồng hồ đo kiểm tra áp suất chân không TOYO TECH NPA TB-3-1, TB-3-2
This compound gauge allows the continuous measurements of pressure ranging from positive pressure to negative pressure, thereby enabling the measurement of vacuum pressure and boost pressure of an engine with a supercharger.
Since the use of the provided pump bulb allows the manual application of pressure as desired, this gauge allows testing and making adjustment of a device operated at positive pressure with ease. Two types of gauges for the measurement of positive pressure are available in 100kPa (approx. 1kg/c㎡) and 200kPa (approx. 2kg/c㎡) types.
