1720E Low Range Online Turbidity Meter

-Working principle: The incandescent light emitted from the light source component of the sensor enters the online turbidity meter downwards, and encounters suspended particles in the sample to generate scattered light. A photodetector immersed in a water sample can detect scattered light at an angle of 90 ° to the incident beam. In addition, when a continuously flowing water sample flows through the patented bubble elimination system (US Patent No. # 5831727), the system can remove bubbles entrained in the sample stream, thereby eliminating the most significant interference in low-range turbidity measurement ; The system is not affected by changes in sample flow rate and pressure. -Application industry: online turbidity meter can be applied in different places

Product description
Technical indicators
- working principle:
 
The incandescent light emitted from the sensor light source assembly enters the online turbidity meter downwards, and encounters suspended particles in the sample to generate scattered light. A photodetector immersed in a water sample can detect scattered light at an angle of 90 ° to the incident beam. In addition, when a continuously flowing water sample flows through the patented bubble elimination system (US Patent No. # 5831727), the system can remove bubbles entrained in the sample stream, thereby eliminating the most significant interference in low-range turbidity measurement ; The system is not affected by changes in sample flow rate and pressure.
 
-Application industry:
 
On-line turbidity meter can be applied to filter devices in different places to measure the turbidity of raw water or pure water. Such as water plant before and after filtration, sedimentation and turbidity monitoring of factory water; municipal pipe network water quality monitoring; industrial process water quality monitoring; circulating cooling water, activated carbon filter effluent, membrane filtration effluent, etc.
 
-Instrument features:
 
● The 1720e online turbidity meter has a built-in patent bubble elimination system to effectively prevent bubble interference
 
● The 1720e turbidity meter is easy to clean and maintain, and can be corrected once every three months
 
● 1720e online turbidity meter has good reproducibility and is not affected by sample flow rate and pressure
 
● The calibration of the 1720e turbidity meter is flexible. It can use the two-point calibration method of 0 and 20NTU (recommended calibration method), or it can be single-point calibration by comparison (any point within 1-40NTU range)
 
● 1720e online turbidimeter measurement unit: NTU, in addition to a variety of auxiliary measurement units for display: FTU, TE / F, mg / L
 
● 1720e turbidity meter adopts USEPA (US Environmental Protection Agency) certification method
