Automatic high precision dispenser SD300 is using pedal switch making liquid out by high pressure in setting period. It can be adjusted flexibly for the manual, semi-automatic. We have use high-precision digital controller to control dripping time accurately even millisecond. So it can control liquid flux to avoid wasting. As long as pressure, time and right needle, it is easy to change the dripping quantity and dripping time. This machine could solve many problems, it is easy and fast for operation with a vacuum suction function to control different viscous liquid to prevent the leakage. High efficiency, easy fatigue, no waste, wide using, we have complete product, we can provide different types of syringes, needles according to user's need. Technology parameter Power supply: AC 220V± 10%/50Hz Wasting power: <8W Air supply: Max 0.99 MPa(clean and dry air) Adjusting pressure range: 0.05MPa-0.7MPa Changing time range: 0.01s-30s, changing DIP switch to get more time modes. Function mode: Manual and automatic modes Accuracy: ± 0.05% Frequency: 600/minute Minimum quantity: 0.01ml Dimension: 235mmx225mmx63mm Weight: 2...2kg Feature: Digital and time-lapse use 0.18CV constant currency controller indicator light switch. Wide using and it can be used drop liquid including drip-dry gluewater, red gluewater, yellow gluewater, resin, lube gluewater, secondary solder and tin slurry. We can match ten different stainless steel pin to play function of dropper
