The liquid density meter, based on the classical Archimedes principle, uses a force sensor based on the electromagnetic force balance principle that is highly sensitive, accurate, and repeatable. It can automatically, conveniently, accurately, and quickly test the specific gravity of solids and the density of liquids. By utilizing the weighing function of this instrument, it can also replace electronic scales with corresponding weighing and accuracy.

It is widely used to test the density of various liquids (aqueous solution, oil, essence, spice, paint, etc.).

The main features of a liquid density meter are:

1. Like similar instruments imported from Europe and America, the weighing technology adopts high-precision electromagnetic force balance principle, which has the characteristics of high sensitivity, accurate weighing, and excellent repeatability (currently, the most common device on the market is a simple device that uses strain gauge technology sensors. Apart from low cost, other technical performance is not on the same level, which is really far behind);
2. The sample stage can be raised and lowered, and the standard volume piece for measuring density can be slowly immersed into the tested sample to minimize measurement errors;
3. Automatically display measurement results without the need for manual conversion;
4. . There are multiple options for liquid density testing standard components, which can meet the testing needs of liquids with certain viscosity and corrosive liquids.

5. Optional constant temperature cup and constant temperature bath can be used to accurately maintain the temperature of the tested sample.

6. STN wide viewing angle backlit LCD display;
7. Automatic zero position tracking;
8. Dynamic temperature compensation;
9. Automatic range calibration;
10. Full range tare removal;
11. Automatic fault diagnosis;
12. Overload alarm;
13. Overload protection;
14. RS232 interface output

The standard volume part is made of 5 cubic centimeters of stainless steel material. If you need to measure corrosive liquids with strong acids and alkalis, you can choose a standard volume part made of 5 cubic centimeters of glass material and platinum wire

The density balance/specific gravity balance fully complies with the following standards:

ZMD series electronic automatic density meter

The ZMD series electronic automatic densitometer is specifically designed for testing the density or specific gravity of objects. Compared with density scales on the market that add a density measurement device on top of an electronic balance, it has the following obvious advantages:

① A regular density balance, the liquid used to test solid density, and the sample used to test liquid density are all placed on the scale pan of an electronic balance. If these liquids spill over, they will flow into the sensor under the scale pan, which can be repaired or scrapped. And our automatic electronic density meter is specially designed for measuring density. The sensor is placed on top of the scale pan, and even if the liquid is completely spilled, it has no effect on the sensor. In addition, the operating space is large and testing is very convenient.

② The use of large water tank glass cups effectively reduces the error caused by the rise of liquid on the suspension bar and improves the accuracy of testing.

③ The built-in standard program uses pure ethanol as a medium for measuring solid density, which is very useful for measuring solids with densities less than 1 and greater than 0.8, especially plastic particles. A regular density balance can only use water as a standard medium and is powerless for samples with a density less than 1. In addition, samples such as plastic particles can produce bubbles when placed in water, which can affect measurement accuracy, but placing them in ethanol can effectively eliminate bubbles. So, precisely because of this special feature, our density meter has a lot of users in industries such as rubber and plastic.

④ Our electronic automatic density meter adopts the same high-precision electromagnetic force balance principle measuring device as similar instruments imported from Europe and America. Compared with the simple measuring device based on the strain gauge principle of commonly used low precision electronic balances in the market, it has the characteristics of high precision, high accuracy, high repeatability, easy operation, safety and durability, or absolute advantages.
