Overview

Rubber specific gravity meter DST-A300 has a stable range of 0.005g-300g; Density accuracy is 0.001g/cm3. The DST-A300 specific gravity meter is suitable for various solids, particles, and floats, and can directly read the volume of objects; Used in industries such as rubber, plastic, wire and cable, food, composite materials, cosmetics, shoe materials, glass, precious metal hardware recycling, etc.

Product Details

Rubber specific gravity meterFunctions of DST-A300:

Equipped with temperature compensation settings and solution compensation settings, it offers more user-friendly operation and better meets the needs of on-site operations.

Equipped with RS-232C computer interface, it can easily connect PC and printer.

Adopting a large water tank design to reduce the error caused by the buoyancy of the suspension line.

When using corrosive liquids as media, an anti-corrosion water tank can be purchased as an option.

② Put it back into the water and measure its weight. Press the MemoRY button to store and display the density and volume values.

working principle ：

Rubber densitometerDST-A300It is made by using Archimedes' principle of buoyancy in water, focusing on the two variables of empty weight and water weight of rubber samples, to measure the relevant density values. And based on the temperature4℃When, the density of water is1.000g/cm3based on.

Preparation before measurement

1、According to the above principle, it can be inferred that the main factor affecting the final measurement result is the weight of the rubber sample in the airW1And the weight in the waterW2Therefore, in order to accurately test the density value of rubber blocks,W1andW2Accurate measurement of two weights is crucial.

2、In order to accurately measure the density value of the rubber block, the following preparations need to be made:

3、95%or75%The alcohol100ml

4、One disposable water cup

5、A piece of dry cloth

6、Standard Accessories

Rubber densitometerDST-A300ofmeasurement method ：

1、After turning on, use it first100gWeight calibration instrument;

2、Place the rubber sample to be tested on the measuring table and press the button on the panelMemoryKey, memorize the weight of the test sample in the airW1；

3、Pick up the rubber sample with tweezers and wash it in a disposable water cup filled with alcohol(Try to wash for a while as much as possible, mainly to prevent bubbles from adhering to the surface of the rubber block when it is placed in water, which will affect the final measurement value)；

4、Use tweezers to pick up the rubber sample, lift up the measuring panel, and carefully place the sample to be tested into the water tank (if there are bubbles on the surface of the sample,Can be sucked off with a straw）Press againMemoryKey Memory Sample Water WeightW2，2～5The measured specific gravity value will be displayed in seconds.
