DMPY-3C type surface tension measuring experimental device Introduction: The instrument is used for measuring the surface tension by the maximum bubble method, no mercury pollution, safe and reliable. The instrument adopts single-chip measurement system with high precision and convenient use. The sensor uses imported precision differential pressure sensor. The core of the instrument is the inter89C51 chip, which can be interfaced with a computer. Users can specify when ordering. Features: 1. Integrated design of peristaltic pump, micro differential pressure measurement and surface tension device. 2. The peristaltic pressure output replaces the drip pressure to avoid the problem that the glass instrument is easily broken. 3. The pressure output is adjustable in 10 steps and the bubble overflow rate is easier to control than the glass piston drip. 4. The pressure output can work continuously for a long time without interruption due to water replacement. Technical indicators: 1. Pressure difference pressure adjustment and measurement range: -10 KPa to +10KPa 2. Differential pressure resolution: 1Pa 3. 4 1/2 display with peak hold function 4. Peristaltic pump pressure is adjusted in both directions, and can work in positive pressure mode or negative pressure mode. 5.Pressure output control: 10 steps digitally adjustable 6. Peristaltic pump, micro differential pressure measurement and surface tension tube device integrated design
