1、 Product Overview

The KD-35B COD rapid digestion instrument is a heating device for rapidly measuring chemical oxygen consumption. Sample digestion pretreatment can be performed for COD, total phosphorus, total nitrogen, and other parameters. Starting from 2014, Kaida has upgraded to be equipped with standard hash sealed digestion tubes of the same level. In order to ensure safe use and facilitate customer observation of samples during the experimental process, Kaida Environmental Protection has upgraded its configuration with a transparent digestion protective cover. Prevent liquid splashing from causing harm to the human body.

This instrument can automatically complete the constant temperature timing time, with a time setting of 10-15 minutes. After the temperature constant time is reached, the instrument has an automatic sound alarm function, automatically shuts down, and does not require manual intervention. Small temperature drift and high constant temperature accuracy. It adopts the latest international 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. Compared with the current reflux device for determining chemical oxygen demand using potassium dichromate method, it has the advantages of small volume, water saving, electricity saving, and good constant temperature performance. Suitable for heating and rapid determination of chemical oxygen demand (COD), the obtained data corresponds perfectly to classical methods and 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, making COD measurement efficient, fast, and economical.

The KD-35B digester has replaced KD-35D (20 wells) and KD-35E (25 wells) as a universal model. We can customize the number of samples according to customer requirements.
