Aumeascon AM-L-BOD5 Laboratory BOD5 Analyzer

AM-L-BOD5 Laboratory BOD5 Analyzer

Introduction

Aumeascon AM-L-BOD5 Laboratory BOD5 Analyzer: Biochemical oxygen demand (BOD5) is an important test items of water quality evaluation and also an important quality indicator of water pollution. The traditional method of BOD5 is chemical dilution. But the method often obtained imprecise results, because it is tedious, need higher experimental skills and large dispersion of experimental data.

Our new equipment use Air pressure method, which operation is simple and can obtain accurate and comparable measurements with chemical dilution and intuitive reading, easy to use and maintain. It is a powerful tool for the general analysts, and widely used in enviormental monitoring, petrochemical, health care, teaching and research departments on the water quality monitoring. 

Pour water sample into a culture bottle with sodium hydroxide in seal cup on bottle mouth, then seal the bottle and put in the incubator, keep the temperature at 20℃±1℃ and Continuously stirring for 5 days. Organic matter in the sample will be converted to the oxides of nitrogen, carbon and sulfur because of the biological oxidation. During this process, the only gas (CO2) overflow from the sample then is absorbed by sodium hydroxide. At the same time, oxygen consumption of microorganism results in air pressure difference. The BOD5 value can be calculated through measuring the height of the mercury.

 

Technical Specification

1. Measuring Range: 0mg/L～1000mg/L(dilute if BOD5 value exceeds)

2. Accuracy: meet Chinese national standard “GB7488-87”

3. Display: read the value BOD5 from dividing rule of pressure gauge（mg/L）

4. Sample Quantity:  8 

5. Culture Temperature: 20℃±1℃

6. Main unit Dimensions: 400mm×270mm×350mm

7. Power Consumption: < 15W

 

Packing configuration 

1 BOD main unit, 10 culture bottles, 10 stirrers, 8 CO2 absorption cups, 1 bottle of mercury,  rubber conveyer belt ( big and small each 3 strips), 2 airproof circles, 2 fuses, 1 Power AC-DC converter.

Aumeascon AM-D-NH3N Digital Ammonia Nitrogen Sensor

图片
AM-D-NH3N    Digital Ammonia Nitrogen   Sensor Brief Introduction Th e Aumeascon AM-D-NH3N is digit al online ammonia  nitrogen sensor and with RS485 Modbus,it measure the ammonia nitrogen concentration by an ion selective electrode method.   The ammonia  ion selective electrode directly detects the ammonia  ion in the water environment to determine the concentration of ammonia  nitrogen. Use a pH electrode as a reference electrode for better stability. The concentration of ammonia  nitrogen in the measurement process is easily interfered by potassium ions, so potassium ion compensation is required. The   digital   ammonia  nitrogen sensor  is an integrated sensor that is composed of ammonia  ion selective electrode, potassium ion (optional), pH electrode and temperature electrode. These parameters can mutually correct and compensate the measured value of ammonia  nitrogen, and meanwhile achieve the measurement f...
