Product Introduction

LH-C700 is the newest portable multi-parameter with LHOS operating system. It has a built-in lithium battery and digestion module, suitable for outdoor operation. The equipment has powerful detection functions and supports pH/dissolved oxygen/conductivity/ORP/salinity/turbidity/COD/ammonia nitrogen/total phosphorus/total nitrogen/heavy metals/inorganic matter, etc. It adopts an integrated dual-temperature zone digestion and colorimetric design, retains the dual-diameter rotating tube colorimetric function, and has the on-site law enforcement function of taking photos and videos. It is a powerful assistant for comprehensive law enforcement in the wild.

Functional characteristics

1) Electrode method + spectrophotometry: basically covers all the needs of outdoor water quality testing, convenient and worry-free;

2) 360° rotating colorimetry: supports 25mm and 16mm colorimetric tubes for rotating colorimetry, and supports 10-30mm cuvettes for colorimetry;

3) 720P high-definition camera: on-site photo taking or video recording, recording field testing information;

4) 12-hole dual-temperature zone digestion: two temperature zones are independently controlled, suitable for multi-index and batch project testing

5) No battery life anxiety for outdoor testing: built-in 19.2Ah high-capacity lithium battery, up to 8 hours of battery life under comprehensive working conditions;

6) Standard curve formulation and calibration: supports custom calibration of coefficient curves and sample curves;

7) LHOS operating system: based on Android customization, the interface is simple and easy to use, and the data analysis is powerful;

8) Digital electrodes are accurate and stable: signal transmission and processing efficiency are faster, strong anti-interference and accurate measurement values.
