Product Details
YBOD-8 measuring instrument
Equipment Introduction
Product Introduction
A new type of instrument for measuring biochemical oxygen demand using air pressure difference method, which can accurately provide measurement results comparable to chemical dilution method. It has the characteristics of intuitive reading, clear biochemical reaction curve, and easy use and maintenance. It is an ideal tool for job analysis and can be widely used in environmental monitoring, petrochemical, medical and health, teaching and research departments to monitor water quality.
Measurement range: 0-1000mg/L (dilution is required when BOD5 value exceeds the measurement range)
Batch processing capacity: 8 samples
Accuracy: Complies with the national standard GB7488-87 (BOD5 value of glucose glutamic acid standard solution is within the range of 180mg/L-230mg/L)
Display: Large screen LCD with 6 or 8 channels displays BOD5 value
Cultivation temperature: 20 ℃± 1 ℃
Power supply: AC220V ± 50HZ ± 0.5HZ
Power consumption: Instrument ≤ 70W Constant temperature box ≤ 300W
1. Automatic shutdown.
2. Non porous device ensures accurate B O D measurement.
3. Automatically collect and store data.
4. Convenient button interface.
5. Simply press the button to directly print the display image.
6. Input and output through RS-232 interface.
7. Independent channel characteristics can measure 16 sample parameters separately.
8. LCD graphic display continuously updates BO D test results and status.
9. The electromagnetic stirrer continuously stirs to ensure that oxygen is replenished into the sample.
10. Sample dilution solution can measure high range BOD.
1. The BOD testing device can be operated unattended:
The standard five-day dilution method requires tedious sample preparation and operation to obtain reliable results, a microcomputer controlled BOD testing device, and a simplified BOD method. You can quickly and accurately complete important tests, and the entire device operation process can be unattended.
2. Easy to use and effective:
The operator only needs to simply add the measured sample and BOD nutrient buffer to the BOD bottle, connect the bottle to the pressure sensor of the microprocessor control device, select a suitable range from the four ranges, and the BOD testing device can complete the subsequent tests. After the sample temperature stabilizes, the device begins to read the BOD value and store it in the instrument's memory. It is recorded every 15 minutes and can be tested for a period of 5 or 10 days.
3. Effective and complete analysis:
During the BOD measurement process, the sensitive pressure probe of the BOD testing device continuously monitors the changes in oxygen consumption of the sample. The instrument directly measures the BODmg/L concentration without calculation or extrapolation, and uses a pressure probe to avoid the use of mercury pressure gauges and dissolved oxygen measurements.
4. The BOD testing device electronically stores measurement data and updates the results. The rate of B O D change can be detected on the LCD display screen at any time during testing. It can store 480 points of data during measurement.
