Product Overview:

The DRB200 COD digestion instrument (intelligent digestion instrument) can perform total phosphorus, total nitrogen, TOC, and COD digestion, with digestion time and temperature selectable between 0-480 minutes and 37-165°C, respectively. To meet broader usage needs, the DRB200 COD digestion analyzer offers two configurations: single heating block or dual independent heating blocks. The dual heating blocks support simultaneous digestion of water samples under different temperature and duration settings. The digestion in the heating block of this intelligent digestion instrument comes in three size specifications, suitable for TNTplus pre-treated reagents with barcodes (13mm), standard TNT pre-pre-installed tubes (16mm), and pre-pre-treated metal digestion tubes (20mm).

Working Principle:

The DRB200 COD digestion instrument (intelligent digester) uses a heating module and preset heating program to heat and digest COD, TOC, total phosphorus, total nitrogen, and other water samples according to different pre-prepared reagents.

Instrument Features:

• Advantages in digestion efficiency
• Dual heating blocks independently controlled: Digestion temperature and time can be flexibly adjusted, with adjustable temperature range from 37°C to 165°C and time range from 1 to 480 minutes.
• Reagent compatibility advantages
• Multiple pore sizes for pre-prepared reagents: Equipped with multiple heating pore sizes, it can dissolve water samples such as COD, TOC, total phosphorus, and total nitrogen for different types of pre-prepared reagents.
• Security protection advantages
• Automatic alarm prompt: Equipped with a digital timer, it automatically cuts off and alarms after reaching the set digestion time, offering high reliability.
• Fully isolated safety design: Adopts an isolated locking design, equipped with a transparent protective cover and overheat safety device.

Application Areas:

The DRB200 COD digestion instrument (intelligent digester) can be used in fields such as industry, municipal, environmental protection, and university research to heat and melt water samples such as COD, TOC, total phosphorus, and total nitrogen.
