Brief introduction

MultiDirectMulti parameter photometer with modern design, microprocessor control, ergonomic buttons, and a large chart display screen. Pre set multiple parameter method curves, which can be tested using tablets, water agents, pre made test tubes, and powders.MultiDirectuse6Wavelength interference filter, uniquely designed, the instrument can automatically select the corresponding wavelength according to the user's selected method, without the need for any moving components. Moreover, thanks to its dual beam system and built-in reference channel, the instrument ensures measurement accuracy. It can measure multiple parameters simultaneously, has a wide range of applications, accurate measurement, and convenient operation. Measurable includesCODResidual chlorine, total chlorine, total phosphorus, total nitrogen, ammonia nitrogen, hardness, phosphate, sulfate, as well as iron, copper, etc100 Ion concentration analysis. It can be powered by batteries or external power sources, and is suitable for laboratory analysis and on-site monitoring needs.
