Features
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.
