Performance Characteristics

1. Select valve components: Choose reagent sampling timing, flexible and diverse channels, versatile functions, and advantages such as easy maintenance and high lifespan.

2. It has printing function and can be connected to a printer (optional) to print the measured data in a timely manner.

3. Adopting a 7-inch touch screen and a simple operating interface, it can be easy for users to learn, operate, and maintain.

4. The ultra large data storage capacity enables the preservation of historical data for no less than 5 years (with a measurement interval of 1 time/1 hour), meeting the needs of customers.

5. Automatic liquid leakage alarm function, when a reagent leakage occurs, the instrument will automatically alarm and prompt the user to perform maintenance.

6. The use of optical signal recognition function ensures high accuracy in quantitative analysis.

7. The maintenance of chemical reagents is simplified and convenient, with a monthly replacement of reagents, greatly reducing the maintenance workload for users.

8. Accurate measurement of COD at 35000mg/L chloride ions can be achieved.

9. One click upgrade of USB flash drive makes software updates easier.
