♥Directly read the density, concentration and purity of precious metals such as gold and platinum. ♥With temperature compensation setting and solution compensation setting functions, the operation is more humanized and better meets the needs of on-site operations. ♥With the function of density upper and lower limits, it can judge whether the specific gravity of the measured object is qualified. Equipped with buzzer device. ♥The density measuring table is integrally formed by injection molding, which is convenient and quick to install and has a longer service life. ♥The integrated corrosion-resistant large water tank design reduces the error caused by the buoyancy of the hanging rail line, and is also convenient for testing large objects.
