Electronic hydrometers can be divided into plastic electronic hydrometers, rubber electronic hydrometers, cemented carbide electronic hydrometers and powder electronic hydrometers according to their materials. Plastic electronic hydrometer is just one of them. Next, the plastic electronic hydrometer DH-300 will be described from the aspect of characteristics
Plastic electronic hydrometer is an electronic hydrometer that specializes in measuring plastic density meters. The plastic electronic hydrometer is designed according to international standards such as ASTM D792, GB / T 1033, HG4-1468, JIS-K-6268, ISO 2781, UL, IEC, CCC, VDE, etc. The developed product adopts Archimedes' principle, through the derivation and transformation of buoyancy and density calculation formulas to form an equation, first of all, the high-precision solid analysis balance is used to calculate the weight of the sample to be measured in the air (W1) and the water Weight (W2), and calculate the W1-W2 value, the water density defaults to Ï = 1, and establish the equation by V sample = V drainage, you can calculate the density value of the sample: Ï = W1 / (W1-W2) xÏ water, this is the solid calculation formula. If the sample to be tested is a liquid, first use a standard block with a known volume and density as a reference, and obtain the calculation formula from the density of water Ï and the weight of the standard block in air (W1) and the weight in water (W2): Ï Liquid = (W1-W2) / standard block V xÏ standard.
Compared with the previous instruments for measuring the density of plastics, this plastic electronic hydrometer has many of its own advantages:
★ Fast measurement time, only ten seconds
★ The measurement operation is simple, and the operation can be completed in a few steps
★ Precision measurement results, density accuracy can reach one thousandth, or even one ten thousandth
★ Stable performance
★ The instrument can be repeatedly and continuously measured with automatic zero tracking, buzzer alarm, overload alarm function
★ It has the function of setting the density on-line first, which can automatically judge whether the style is qualified and give an alarm prompt
★ With solution compensation function, use water as medium or other liquid medium
★ With the actual water temperature compensation function, it can adapt to the test environment changes
★ It has the functions of measuring medium density setting and waterproof treatment medium density setting
★ Adopt one-piece large-capacity professional measuring platform, high transparent watercolor, wear-resistant, drop-resistant, anti-corrosion
★ Equipped with integrated windproof and dustproof cover
★ Easy to assemble
★ Sturdy and durable
★ The measurement result will be automatically displayed on the instrument at the end of the test
★ The weight of the sampled plastic can be read out, eliminating the step of measuring the weight of the sample with a balance.
