13. Standard residual chlorine calibrated Reagent Pack, residual chlorine/total chlorine Reagent Pack and Portable Protective Case
Principle
The instrument irradiates the sample with 515nm LED Illuminant, and automatically calculates the residual chlorine or total chlorine concentration by measuring Absorbance change and intelligently determining the end point of the reaction. Support dilute ratio setting, which can automatically convert the original sample concentration.
Applications
Water quality testing, environment monitoring, drinking water safety, swimming pool water quality control, industrial water treatment
Steps
1. Turn on and select Measurement mode (residual chlorine or total chlorine)
Add Sample and Reagent to 25mm Colorimetric Bottle
3. Colorimetric bottle into the measurement tank
4. The instrument automatically determines the destination and displays the reading
5. If you need to calibrate, execute (1~ 3) point calibrating procedure
6. Data can be stored, transmitted, or printed
Notice
• Operating Environment Temperature 5~ 35 ℃, relative humidity not more than 85%
• Periodically calibrated to ensure Measurement accuracy
• Use Standard Reagent Pack to Avoid Contamination
• Pay attention to the battery status prompt when charging
• Avoid severe impact or water immersion (although with IP65 protection)
• Store data and back it up in time to prevent loss
