Product Parameters

 

Product Introduction
The LSPEC 7010 CODCr Online Analyzer employs the national standard potassium dichromate method for high-temperature digestion and analyzes using photometry. It determines COD by measuring the linear relationship between absorbance and the COD value of the water sample.

The instrument utilizes an injection pump and multi-level liquid level control for precise measurement, resulting in higher accuracy and reduced reagent consumption, significantly decreasing measurement time. Additionally, it features a user-friendly interface and a systematic fault diagnosis function, making it more convenient and efficient for users to operate and maintain.



Features

1. Injection Pump Sampling Technology: Utilizes an injection pump sampling technique for enhanced longevity.
2. Multi-Stage Optical Metering Technology: Employs multi-level optical metering for higher accuracy and shorter measurement times.
3. Dual-Beam Spectrophotometric Analysis: Utilizes a dual-beam spectrophotometric method for increased precision in detection.
4. Precision Temperature Control System: Incorporates a precise temperature control system for accurate digestion process control and improved detection accuracy.
