Product Introduction

Lianhua LH-C600 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.

Functional characteristics

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;

6. Dual temperature zone design: 6+6 dual temperature zone design, 165°C and 60°C 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.
