C.O.D Apparatus for Water Testing Lab

C.O.D Apparatus for Water Testing Lab

C.O.D Apparatus is applicable to the environmental protection industry and is convenient for the determination of COD in large quantities of samples. C.O.D Apparatus chemical oxygen demand measuring instrument abandons the traditional complex and bulky light splitting system and adopts a new LED as the light source, which greatly reduces the volume and weight of the measuring equipment.

Features

C.O.D Apparatus can produce sine wave and square wave

The metal shell has excellent electromagnetic compatibility and beautiful appearance

Dial display frequency

Touch the switch and the panel function indication makes the operation more convenient and comfortable.
