Description
1.Instrument Introduction
LH-C700 adopts Lianhua's self-developed LHOS operating system. The instrument 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.
2.Features
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.
