In order to ensure the stability and accuracy of the Moisture Analyzer, we need to calibrate the equipment regularly. Today, let's take a look at the calibration specifications of the moisture analyzer.
When calibrating the moisture analyzer, the glass fiber paper was placed on a moisture analyzer sample pan and prebaked at 105 ° C for 10 minutes. Turn off the heating device, adjust the weight on the measuring device, return the indicator of the moisture analyzer to zero, and record the weight value R on the weighing pan at this time.Remove the 5kg Calibration Weights on the measuring device, and measure 5 ml of sodium chloride solution with a 5 ml pipette, and evenly drop it on the glass fiber paper, and turn on the measuring device. After balancing, write down the scale line at this time. The value and the weight value on the weighing pan. Turn off the measuring device, turn on the heating device, and warm up to 105 °C.
After 1 hour, the measuring device is turned on, and the weight on the measuring device is increased or decreased to read the balance position on the display screen. After the value to be displayed is stabilized, record the mass value of the increase and decrease weight and the final equilibrium position, and calculate the moisture of the sample according to the calculation formula.
When the moisture analyzer is calibrated, the standard drying procedure is selected at a temperature of 105 ° C at a water loss rate of 1 mg / 60 s. Glass fiber paper was placed on the sample pan and prebaked at a temperature of 105 ° C at a water loss rate of 1 mg / 60 s. After the pre-baking, 5 ml of sodium chloride solution was pipetted with a 5 ml pipette and dropped as evenly as possible on the glass fiber paper, followed by moisture measurement, and determined by the 1 mg/60 s water loss rate method. The final moisture value.
At the same time, it should be noted that if the moisture analyzer has a matching weight, it will be corrected according to the corresponding weight level.
