Product Description

1>Product Introduction

The Portable COD Analyzer LH-COD2M is mainly used to test COD in the field, and is supported by portable intelligent batteries, portable test cases.

2 >Functional characteristics
1, Without power supply, direct measurement of chemical oxygen demand (COD).
2,Getting the results just in 20 minutes.
3,Pre-storing 5 standard curves can be revised and saved.
4,The instrument can automatically calculate and store the curve according to the standard sample.
5, Can store 5 thousand measurement data (date, time, parameters, determination results).
6,Equipped with printer to print current data and historical data.
Transmit current data to computer, support USB  transmission
7, Equipped with a 4 samples intelligent reactor ,meets the demand of users for testing large quantities of water samples.
8,According to the quantity of load, rated Power of reactor is adjusted automatically and the intelligent constant temperature control is realized.
