Does the measurement on this syringe compensate the fluid in the tube or does the user have to figure out how much the tube holds for precision?

The graduations on the syringe should compensate for the amoun of fluid in the tip of the syringe, but I would advise measuring the amount of fluid in the tubing separately. I would not use this syringe for precision scientific work.

Cannot say definitively, but it is a very different consistency from the tube I purchased 2 years ago. Both work well though!

No, It only measures by the cup. You can adjust the amount the cup will dispense with a knob so I think you could calibrate, with a scale, the amount that is dispensed by weight. I bought this machine because it is excellent in it's consistency of the grind and the and the amount it dispenses.

Some people use much smaller syringes, and need the spacers removed, or the needle won't reach the skin. I don't use any spacers for my 3/10cc syringes, but you need to use a different cap (that comes with it), and sometimes spacers for the larger sizes, like 1cc. From 'cocked', to 'fired' it only about half an inch, maybe even less. The needle, once fired, should just stick out of the device, with the base of the needle almost flush with the opening. I use the short needle, so I can't cut down on how deeply it injects, but I imagine if you use the traditional length you can adjust the depth with spacers.

Here is the deal I will bring home a 5ml syringe ( I am an aesthetic nurse) and fill my empty bottle with 4.5 ml and tell you what my results are and follow up with you. I have a no BS policy and get to the bottom of things .

Yes the unit is adjustable, but there is no gauge to let you know the exact pressure you've set it at.

you can use a manometer which works in a similar fashion to a vacuum gage synchonizer except it uses tubes of fluids. The benefit is that you don't have to worry about a shaking needle just that the levels of fluids are all the same.

Mg are a measure of weight and different liquids have different weights so I don't see how a syringe could have mg measurements. The syringe measures in volumes and there are syringes that have ml and/or cc measurements. I think you have mistaken mg with ml. To measure mg, you would have to use a very accurate weight scale for measuring that small of a weight.

I had a pen syringes and just replaced the tips so I had no problem. Not sure about a full syringe.

Yes it will, not very accurately though. But it goes from 0.001g to 20.000g. If you really need to be precise to the mg, I recommend spending more money.

BEATS ME, I SENT MINE BACK. I believe the bite valve was straight, as was the place where the tube exits the cap. 'Believe', not sure. I sent mine back, unused, as the tube was too short to be useable.

In my review, I noted that while it claims to be a 0.5 tbsp. (7.5ml) scoop, when I measured the actual volume with a medicine syringe, I got 5.2ml, which is a teaspoon.

Small enough to do the job you are proposing, the tubes vary in size from diameter of a common drinking staw, then size of a pen/pencil, then D shaped for the largest about the size of a sharpie. My wife loves them !!! (We use a 60cc catheter tipped syringe with the stopper removed for the same purpose)

Approximate sizes, the straight needle is about 1 3/4" or 46mm long-2mm diameter and the curved needles are 2 1/8" or 55 mm long-3mm diameter. I don't know where others got 4". They must have measured up one side and down the other or SWAGGED an estimate. I used an accurate caliper. Dick

Yes, it has markings in ml broken down further in smaller fractions. Technically you can go down further than 0.05 ml but precision will suffer, although accuracy will still be reasonable. For 0.05 ml, both will be reasonable.

The needle moves according to how much 'electric current' flows through the metal wand. Essentially, water is the conductive substance. If the soil is dry, no ions can pass anywhere and the needle will not move, so it is dry. The more water, the easier for ions to pass and that makes the meter get its' power. This is more than adequate accuracy for plants. If this were ultracritical and you needed a specific readout of the percentage of water, etc. this isn't the unit. For everything else, it is a winner.
