Efficient and Versatile: Jebao DP-3 Programmable Auto Dosing Pump with 3 Channels in Sleek Black Review

This automatic dispenser does what you want, although as others have said it needs finer calibration. First follow YouTube's instructions to calibrate it and after tweaking it on my system I've adjusted the dosage as needed. Let's say if I needed 30ml I would set it to 30 which would be a dosage of 34. However, if you set it to 27, it would dose to 30, which is what you need. It was difficult to set up at first but I had no problems with it and for the price compared to others it at least gets…

I read the reviews before buying so I already knew that frequency 0 means every day. but this thing won't stay refilled for more than 24 hours. If you have thousands of dollars worth of coral, don't trust this inexpensive donor. I've tried everything I can think of (silicone tubing, zip ties on connectors, swapping pump heads) but nothing has prevented the lines from refilling with air. which caused my alkalinity to always drop (because no solution was actually provided). I've just ordered a…

That's a lot. Easy to set up and calibrate but I noticed that when calibrating to 100ml it dispensed 2ml instead of 1ml so I calibrated to 50ml and now it dispenses correctly. 1 star for that. My instructions came in English, I saw some reviews here that said they were in Chinese. In general, the purchase is satisfied. Update April 2, 2019: My lines kept emptying with this pump, which was annoying. This can be remedied by installing non-return valves at the start of the outlet lines. Seems to…

I bought three of these devices for dosing fertilizer in planted aquariums. I calibrated with a good quality graduated cylinder, but all three units overdose by about 1-2mL for volumes below 10mL and 2-3mL for volumes between 10-20mL. Not a major issue, easy to account for when creating a dispensing program. My biggest complaint is that the backlight on one of the screens never turns off, the backlight on other devices turns off after about 30 seconds of inactivity. The one in question stays on

Easy to set up and use. The instructions are not that difficult to understand. Just follow the other calibration guidelines. Also use "0" for everyday use. I also had a spare pump head with me. Hose not included. Calibrate to 50ml instead, which is about 110-120 turns on the device (makes more sense when you actually have the product in your hand) and you'll get close to accuracy, always check actual performance after adjustment. I dose small amounts of 1-10ml and this has worked for me. Great…

Instructions are missing so let me help you a little. The equation 100mL = 200 does not mean it is calibrated for 200x dosing to 100mL. You need to calibrate it yourself to stop at 100ml. So you'll probably use around 100ml of your chemical for this, but once that's done you're good to go. YouTube how to get through the menu when the instructions are confusing. I used a measuring glass to calibrate, I started calibrating until the liquid filled the tube and then stopped, this should have filled

After you've hit your head a few times, programming becomes easy. Only installed today 05/03/20, let's see what happens in the morning when the time for the first dose comes. If you don't hear from me again, then everything went according to plan. The device itself looks high quality. The only damn thing are those bright power-on LEDs that manufacturers keep putting on devices. Another light to light up the night. I AM BACK! Happy to report that everything is going well. Dosing pumps CAL and…
