Detection principle:

Principle of residual chlorine and total chlorine determination: Based on the TMB photometric method, standard residual chlorine and total chlorine solutions are developed and designed. The curves are stored in a microcomputer chip using spectrophotometry, allowing users to quickly determine residual chlorine and total chlorine in water samples by adding reagents after sampling. The measurement results are displayed in mg/L.

Product features:

1. Compliant with the TMB photometric method, the measurement is accurate and effective.
2. Adopting imported high brightness and long-life cold light source, with excellent optical performance and a light source lifespan of up to 100000 hours.
3. Large LCD screen with full Chinese display, direct data reading, simple and time-saving operation.
4. It can save 20 standard curves and 200 measured values (date, time, parameters, test data).
5. Memory standard working curve, users can also calibrate the curve according to their needs.
6. It has the function of curve coverage interference to prevent accidental operation of covering curves.
7. One click factory reset, which can quickly recover in case of curve loss caused by misoperation.
8. It has data storage function and data power-off protection function, making it convenient to query historical measurement data and prevent data loss.
