HBUV-1 online ultraviolet (UV) absorption monitoring instrument

The HBUV-1 ultraviolet absorption online monitoring instrument is a water quality online analysis instrument designed based on the ultraviolet absorption method for measuring COD. It is mainly used to monitor the amount of some organic matter in sewage. Compared with other chemical analysis instruments, there is no secondary pollution, the analysis time is short, and it can continuously and accurately measure COD in water online^uvThe measurement process is accurate and reliable, and the operating cost is extremely low. No reagents or sample pretreatment are required during operation, and the turbidity of the sample can be automatically compensated. The conversion coefficient can be adjusted at any time according to the on-site water quality.^{This instrument is controlled by an embedded industrial computer system to automatically collect water samples. After the water sample enters the colorimetric tube, the photoelectric colorimetric method is used to detect the voltage related to chromaticity, which is amplified by a signal amplifier and transmitted back to the industrial computer. After data processing, the embedded industrial computer displays COD}uv^{Concentration values are stored, processed, and transmitted as data.}This instrument can be widely used for COD in municipal sewage, industrial sewage, and surface water^uvMeasurement of Content. The measurement results can be obtained using the Special Absorption Coefficient (SAC) and Chemical Oxygen Demand (COD) values

main features

◇ Large screen LCD display

The instrument adopts a large screen LCD display, which can intuitively display the measurement process, measurement results, reports, and measurement result curves.

◇ Storage function

Using a large capacity electronic hard drive, it can store 10 years of historical data (calculated based on 24 data records per day).

◇ Fixed point analysis function

The analysis frequency and time can be selected (e.g. 3 times/day, 8:00, 10:00, 18:00).

◇ Range adjustment

The appropriate range can be selected according to the water quality condition to ensure measurement accuracy.

◇ Rapid measurement

Measurement of water samples can be achieved within 2 minutes.

◇ Easy maintenance

No need to configure chemical reagents, easy to maintain.

◇ No secondary pollution

Because pure physical methods are used for measurement, there will be no chemical pollution generated.

◇ Accurate measurement values

Adopting advanced dual wavelength measurement methods and adjusting the stability of the light source based on detection feedback, the instrument's measurement values are closer to the true values.

◇ Power off protection function

The instrument unexpectedly loses power during operation, but it can automatically restore its original operating state after being powered on again, and the instrument parameters will not be lost after power failure.

◇ Conversion coefficient adjustment

The conversion coefficient between SAC value and COD value can be adjusted according to the on-site water quality conditions.

Provide 4mA~20mA analog interface output, compatible with various standard data collectors.
