1、 Instrument Introduction

ZL-1AB portable total phosphorus detector is a specialized instrument for measuring total phosphorus developed and designed according to customer needs, based on industry standards. This measuring instrument uses cold light and monochromatic light as light sources, with good optical stability and will not be affected by the interference of GE light. Enhanced the accuracy and stability of the instrument; Guang Fan is applied in industries such as laboratory testing, sewage treatment, colleges and universities, environmental monitoring, sewage treatment, and colleges and research institutions.

2、 Instrument features

1.Microcomputer, touch sensitive keyboard,LCDLCD digital display is clear and easy to use.

2. Using cold light and monochromatic light as light sources, it has good optical stability and will not be affected by the interference of ge zhong light.

3.Our company's technologyLEDThe light source automatic control circuit ensures stable light source and solves the problem of preheating during startup. Its light source has a long lifespan20Year, no preheating is required when starting up, it can be used directly.

4.Convenient to carry, in addition to being used in laboratories and fixed locations, it can also be directly used for on-site water sample measurement and field use.

5.The instrument stores calibration curves within the full range, with power-off protection, and calibration data will not be lost.
