Description
Overview
GAOTek Water Hardness Water Quality Tester is a new generation of water quality analyzer developed for environmental protection, industrial and mining enterprises, schools and scientific research institutes. The instrument is composed of emission light source, new optical system, signal control amplification system, microprocessor intelligent control and automatic display of analysis results, and corresponding chemical kits. This instrument can be applied to the measurement of various parameters such as COD, ammonia nitrogen, total phosphorus, and total nitrogen. With intelligent program design, no manual intervention is required, the measured value is accurate, and it is convenient to use. It is suitable for outdoor and poor experimental conditions. The original intention of the instrument was “to facilitate users to test and use outdoors”, continuously improving the optical path system, optimizing the design procedure, making the measurement data more accurate and the instrument responding more sensitively.
