Chlorine dioxide [CIO2] reagent has been rigorously certified with various measuring tools and containers, carefully prepared in a temperature and humidity environment that meets the requirements, and can be traced back to NIST standard reference materials (SRM)
Easy and fast operation

Take 1mL of HI93737A-0, HI93737B-0, and then 2mL of HI93737C-0, HI93737D-0 respectively. Finally, add 3 drops of pre made silver [Ag] reagent such as HI93703-51 to the water sample to be tested [see operation manual for details]. After the reaction between the sample containing silver [Ag] and the reagent, the color of the sample will change. Then measure the amount of silver [Ag] using colorimetric method, and use the recommended HI96737 and HI833XX series photometers to measure the color change. The concentration of silver [Ag] is displayed as ppm (mg/L) reading.

Kind reminder: To ensure the accuracy and stability of measurement readings, it is strongly recommended that the optimal temperature range for the sample to be tested be 20 to 24 º C

Special Reminder:

In order to ensure measurement accuracy and reading reliability, it is recommended that users use the HI96738-11 chlorine dioxide [CIO2] calibration group to verify the internal standard curve of the HI96738 chlorine dioxide [CIO2] measuring instrument before each use. If the calibration value is within the specified range, users can measure normally. If it exceeds or falls below the specified calibration value range, while ensuring that the operation is correct, check the following factors:

--It is necessary to check whether the calibration group is within its validity period or whether contamination or damage has occurred due to storage reasons;

--Whether the glass colorimetric dish is contaminated or scratched, and whether the battery level is above 30%;

Excluding the above factors, it indicates that the instrument light source system has decayed and needs to be returned to the Hana repair center for processing.
