QCOD-3E COD Analyzer (cuvette detection)
Product Description
The instrument first digests the sample with sealed catalyst, and then measure them by colorimetric method. The instrument adopts advanced cold light source, narrow-band interference technology and microcomputer automatic data processing to directly display the COD (mg / L) value of the sample.
The instrument is widely used in drinking water, groundwater, surface water, municipal sewage, industrial sewage, environmental monitoring, colleges and universities, scientific research institutions and other fields water measurements.

Instrument Characteristics：
● Separating the measuring instrument and digestion unit does not affect the stability of the optical system.
● The measuring instrument uses a cold light source and a narrow-band interference optical system, resulting in excellent optical stability.
● Cuvette colorimetry offers better linearity.
● Large LCD screen with Chinese display for convenient and intuitive operation.
● Digestion unit features PID automatic temperature control and timing for high accuracy.
● Simple and time-saving operation; no tube replacement is required for digestion and colorimetry.
● Digestion temperature and time can be steplessly set for other applications.
● Can save 10 standard curves and 500 measurement values; data is retained even in the event of a power outage.
