C.O.D. Digester (MSW-439)
- A Compact Thermoreactor For Determination Of Chemical Oxygen Demand
APPLICATIONS
- Designed for digestion of COD test samples and multi-function dry bath heating.
- Precise temperature control from ambient +5°C to 150°C with ±1°C accuracy.
- User’s self compensation function for temperature to counter for difference between block temperature and sample temperature.
- Fitted with Microprocessor Based Digital Temperature Indicator cum Controller for autocontrol with respect to time and temperature and is also fitted with IN-BUILT BUZZER TIMER for AUTO TIME CONTROL to indicate cycle end.
- Microprocessor Based Digital Temperature Indicator cum Controller having individual display for set value and process value.
- Size of heating block : 270 mm (L) x 150 mm (W) x 70 mm (D).
- Recessed well/cavity accomodates aluminium insert block.
- Samples after being digested for 2 hours can be analysed using calorimeter or conventional titration method.
APPLICATIONS & KEY FEATURES
- COD Digester is the most accepted Thermoreactor for Determination of Chemical Oxygen Demand in Various Substances. Chemical Oxygen Demand (COD) is a Measure of the Capacity of Water to Consume Oxygen During the Decomposition of Organic Matter and the Oxidation of Inorganic Chemicals such as Ammonia and Nitrite. COD Measurements are Commonly made on Samples of Waste Waters or of Natural Waters Contaminated by Domestic or Industrial Wastes. Chemical Oxygen Demand is Measured as a Standardized Laboratory assay in which a closed Water Sample is Incubated with a Strong Chemical Oxidant Under Specific Conditions of Temperature and for a Particular Period of Time.
- High Performance and User Friendly Controls Combine to Produce a Specification Which Offers Exceptional Efficiency and Reliability. The Benefit to you-convenient, No Fuss Heating!
- Excellent Temperature Control.
- Uniform And Stable Heating
- New Compact Size
