Overview
Enviro Testers handheld measuring refractometer cover plate was opened, and the detection prism was carefully wiped with a soft cloth. Several drops of the solution to be tested were placed on the detection prism, and the cover plate was gently closed to avoid bubble formation and the solution was spread over the prism surface. Aim the light entry plate of the instrument at the light source or bright place and observe the field of view through the eyepiece. Rotate the eyepiece to adjust the handwheel, so that the blue and white dividing line of the field of view is clear. The scale value of the dividing line is the concentration of the solution.
