เครื่องวิเคราะห์ค่า COD MD200-COD

MD200-COD COD Analysis

Product Description

The MD 200 is a single parameter photometer for the measurement of COD.

A waterproof (IP68) housing, high precision interference filters and LEDs used give robustness, reliability, accuracy and confidence in results.

A small footprint, backlit screen, 4 button keypad and scroll memory function which saves the last used range, make the unit easy to use and ideal for testing in any environment.

Results containing date and time can be stored in the on-board memory, and can also be downloaded via an infra-red unit (IRiM) for later review in excel or notepad.

With the added reliability of the Lovibond ® COD reagents the MD 200 is the ideal choice for photometric testing.
