1、 Product Usage:

ZD-1The Type A water quality analyzer is mainly used to determine total nitrogen in sewage. It adopts a rapid digestion method and has a simple, fast, and economical operation process. The measurement results have good comparability with traditional titration methods. This instrument is suitable for water quality testing in large, medium, and small sewage treatment plants and can be widely used in industrial, chemical, environmental protection, and pharmaceutical industries for sewage testing. It is a commonly used laboratory instrument.

2、 Technical parameters:

Instrument calibration

The instrument has been calibrated at the factory and can be used directly. If the user needs to recalibrate, please provide a standard solution by yourself.

Introduction to the Dissolver:

The digestion device has 6 test tube holes, suitable for using 6 reaction test tubes. The heating block of the instrument is made of high-density aluminum alloy extrusion molding, which has the characteristics of large heat capacity, low thermal resistance, and uniform heating. Adopting intelligent digital temperature display, it can be set freely, automatically maintain a constant temperature, and is easy to use. The temperature control accuracy can reach 200 ℃± 1 ℃. It is equipped with a digital timing device, and users can adjust the timing time arbitrarily within a week. Integrated light shielding and dust cover, using test tube without sealing, easy and fast experimental operation.

3、 Product features:

1.It can be automatically zeroed and calibrated from 1 to 5 points.

2.Using an optical colorimetric dish with good reproducibility.

3. Adopting semiconductor light-emitting devices, their light sources are stable and have a long lifespan.

4.999 measurement storage function.

5. Date display function, storing one date and time at a time for easy querying.

6. Experimental results can be printed.

7. The menu is entirely in Chinese and easy to operate.

Note: Due to the different composition of water samples in various industries, this method cannot detect certain organic nitrogen-containing compounds in some water samples.
