Five models are available covering a wide range of 2 PSI to 100 PSI 

These digital manometers are ideal for measuring low differential pressure in clean rooms, test and balance, medical equipment, HVAC, pneumatic systems and computer peripherals. They are portable, and weigh only 5 oz. (150 g) including the battery, these meters are convenient for use in the lab, field or factory. All read gauge, and differential min/max, hold, and auto power off functions. The RS232 port enables communication with a computer. High accuracy of ±0.3% fs at 25ºC, repeatability: ±0.2% (max ±0.5%) FSO, and combined linearity and hysteresis: ±0.2 (Max ±1.0%) FSO. All Sper Scientific Manometers come ready to use with connection hose, instructions, and a 9V battery, in a hard shell carrying case. N.I.S.T. traceable certificate of calibration available.(Option +เพิ่ม 4,000บาท)
