1、 Instrument Introduction

The DS-901A COD constant temperature heater is a heating reflux device that uses air condensation instead of water condensation to measure chemical oxygen consumption. It can automatically complete the constant temperature timing without manual intervention. Small temperature drift and high constant temperature accuracy. It adopts a new type of PID temperature controller, time controller, fast heating speed, small temperature buffer, and constant and uniform temperature. It is easy to operate and is a new experimental instrument product. This instrumentUsed for water quality testing in industries such as environmental protection, healthcare, hygiene, food, tap water, papermaking, sewage treatment, printing and dyeing, petrochemicals, metallurgy, and universities.

2、 Main technical features

1. Equipped with a time controlled constant temperature heater; The time can be set arbitrarily;

2. Automatically calculate the heating and reflux time without the need for manual timing. After the heating and reflux time reaches 2 hours, the instrument will automatically shut down;

3. Small temperature drift, energy-saving, water-saving, low power consumption, fast heating speed;

4. The bottom of the heating plate is made of special materials and processing technology, and each heating hole is kept at a constant temperature and uniform;
