1、 Product Overview

The dual temperature zone intelligent multi parameter digestion instrument is a heating device for rapid determination of chemical oxygen consumption. It has two independent digestion temperature zones, dual temperature and dual control. Sample digestion pretreatment can be performed for COD, total phosphorus, total nitrogen, and other parameters. This instrument can automatically complete the constant temperature timing time. After the constant temperature time is reached, the instrument has an automatic sound alarm function and automatically shuts down without manual intervention. Small temperature drift and high constant temperature accuracy. It adopts PID temperature controller, time controller, fast heating speed, small temperature buffer, constant and uniform temperature, and is easy to operate. It is a new experimental instrument product. It has the advantages of small size, water-saving, energy-saving, and good temperature control performance. It can be widely used in industries such as environmental protection, higher education, medicine, health, food, tap water, chemical industry, sewage treatment, papermaking, petrochemicals, metallurgy, printing and dyeing.

2、 Performance characteristics

1. Simultaneous digestion in dual temperature zones, setting different digestion indicators for different digestion durations according to user needs, without interfering with each other, saving time, and improving work efficiency.

2. The temperature curve display shows the real-time variation of the digestion temperature with the digestion time during the digestion process, helping to observe and understand the temperature changes throughout the entire digestion process.

3. One click start digestion, the instrument preset commonly used digestion index parameters (such as COD, total phosphorus, total nitrogen, etc.), and one click select the corresponding index to enter the digestion operation.

4. Splash proof protective cover, heat-resistant and corrosion-resistant visual splash proof protective cover, convenient for operators to observe the real-time digestion status of water samples, ensuring operational safety.

5. The independent numerical numbering of the digestion well facilitates the differentiation of different water samples for digestion.

6. Over temperature power-off protection, automatic power-off protection when the set temperature is exceeded, to protect the safety of instruments and personnel.

7. The digestion mode can be freely changed, with a wide temperature range and a large time span for digestion, improving the versatility of the instrument and meeting the different needs of different users.

8. Color LCD screen, color touch screen, full Chinese display, user-friendly interface.
