3.Sulfate radical rapid analyzer/Sulfate radical analyzer/Sulfate radical centrifuge/Sulfate radical rapid analyzerH18421

Sulfate radical rapid analyzer (dual digital display - time and speed)

The sulfuric acid rapid analyzer is easy to operate and is used for on-site rapid analysis in chrome plating production workshops (to determine the sulfate content in chrome plating solutions), controlling the sulfuric acid content in chrome plating tanks. It can also be extended to rapid determination of sulfate content in other solutions. Composed of an acid centrifuge and two sulfate measuring tubes

The measurement range is 0.2-5g/L.

Easy to use, fast, and with minimal error, no need to create a working curve, and can accurately determine the content of sulfate ions in the plating solution in just ten minutes. It solves the disadvantages of complex, time-consuming, and high error detection of titration and weight methods, and is an instrument for analyzing chrome plating processes.

① Electric centrifuge (power supply, 220V, 50HZ)
② Two rapid sulfuric acid measuring tubes, plugged, with a measurement range of 0.2-5g/L.
③ . Pipette (self provided) 1 20ml, 2 5ml

Dimensions: Length * Width * Height 36 * 36 * 33cm

Weight: 20kg

Reagent preparation:
① . 3:1 hydrochloric acid solution: Mix 3 volumes of hydrochloric acid and 1 volume of distilled water.
② 0.25% Barium Chloride Solution: Dissolve 250 grams of analytical grade barium chloride in 1000 milliliters of distilled water
Analysis method:
1. Take the chrome plating solution and cool it to room temperature. (If the solution is not clean, filter it.) Use a pipette to take 20 milliliters of the above solution and place it in a rapid sulfuric acid measuring tube. Add 5 milliliters of 3:1 hydrochloric acid to the pipette, shake well, add 5 milliliters of 25% barium chloride solution, cover with a lid, and shake well.
2. Place the centrifuge tube into the electric centrifuge and operate in the following order:
Check for accuracy and cover the panel - check and adjust the speed regulator to zero position - turn on the power - set the instrument timer to the 4-minute position - gradually increase the speed regulator to 1400 rpm.
3. After the centrifuge stops rotating, turn the speed controller back to zero and turn off the power switch. Take out the reading of the centrifuge tube, and the scale value of the centrifuge tube is the sulfuric acid content (g/L).
Notes:
1. The centrifuge should be placed firmly. Two centrifuge tubes must be placed into the centrifuge simultaneously and filled with the same volume of solution, otherwise it will become unbalanced during high-speed operation and damage the centrifuge.
2. The centrifuge tube has undergone calibration and balanced pairing, and should be used in pairs.
3. After the measurement is completed, immediately adjust the speed controller to zero position and clean the centrifuge tube, pipette, etc. in a timely manner
