C series portable multi-parameter water quality Instruments (LH-C600)
Product Introduction
Lianhua C series is a water quality instrument for outdoor detection of users. It uses a spectrophotometry method and built -in lithium batteries. It is an instrument that integrates colorimeter and reactor. 7 inch touch screen, built-in printer.
Feature
1) More than 38 items: direct analysis of chemical oxygen demand (COD), ammonia nitrogen, total phosphorus, total nitrogen, suspended solids, color, turbidity, heavy metals, organic pollutants and inorganic pollutants, etc. direct reading;
2) 360° rotating colorimetry: support 25mm, 16mm colorimetric tube rotation colorimetric, support 10-30mm cuvette colorimetric;
3) Built-in curves: 600 curves, including 480 standard curves and 120 regression curves, which can be called as needed;
4) Calibration function: multi-point calibration, support for making standard curves;
automatically save calibration records, which can be called directly;
5) Recent mode: Intelligent memory of the 8 most frequently used measurement
modes recently, no need to manually add selection;
are simultaneously operated without interfering with each other, and independent work and colorimetry do not interfere with each other;
7) Permissions management: built-in administrators can set user permissions by themselves to facilitate management and ensure data security;
8) Portable in the field: Portable design, built-in lithium battery, with a professional accessory box, to achieve field measurement without power supply.
9) COD test Wavelength Range: 420 nm, and 610 nm 10) Wavelength Selection: Automatic
11) Operating Mode: Transmittance (%), Absorbance and Concentration
