NH-1A ammonia nitrogen detector

1、 Instrument Introduction

NH-1A ammonia nitrogen detectorA specialized ammonia nitrogen analyzer developed and designed based on customer needs, taking into account both industry and industry standards. This measuring instrumentUsing 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.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.After a few minutes of reaction with the reagent, the water sample can be read and the value of ammonia nitrogen in the water sample can be measured.

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

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