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.
