Ammonia concentration of sodium hydroxide hydrometer Professional hydrometer alkaline solution

Patent Number: ZL201320080171.0 three-year warranty Products apply to: sodium hydroxide, ammonia, calcium carbonate, sodium silicate, sodium carbonate, potassium carbonate, dye, bleach production plant and research experimental unit. Principle: Reference GB / T611, T2423, ASTM E126, T18796, ISO 6353 specifications. Application objects immersed in the liquid buoyancy, irregular density and volume weight of the alkaline solution used as a standard test. Specifications: Model: TWD-150BS Test species: SG, Bé °, C% Weighing Accuracy: 0.001g gravity range: 0.0001 to 2.0000 (glass weight) Baume range: 0.1 ~ 80.0 Bé ° concentration range: 0.1% 100.0% standard interfaces: RS-232 special hook: correction 1, with air buoyancy compensation and weight volumetric thermal expansion coefficient and temperature deviation values: TP-14 function. 2, with a Baume set temperature deviation values. 3, according to the proportion of the value of the chemical solution, then apply the proportion of non-linear method to concentration. Features: 1, the body is integrally molded cast aluminum, structural stability. Keystrokes will not affect the measurement sensing element, causing instability problems screen; not because of the alkaline solution overflow penetrate the circuit board and sensor damage problems. 2, the machine's sensors measure the position and the same platform to improve load cause problems on the corner of the measurement bias. 3, the screen mining elevated independent design and measurement station separation. Alkaline solution will not be subject to corrosion and damage caused sticking problem. 4, special hook design and capacity 50CC just read alkaline gravity of the solution, and then converted to Bé °, C%. The key measurement points: Test alkaline solution is the best environment in national standard reference temperature of 15 ℃, 15.6 ℃, carried out at 20 ℃.
