Which refractometer? | Reef2Reef I have used the Milwaukee refractometer for more almost 20 years This summer I got the Vee Gee Scientific STX-3 and it is a very precise instrument and easier to see the scale than the Miwaukee The hand held Hanna tester is also good but you need to calibrate it very often (ideally each time you want to use it)
DIY inline refractometer - Homebrew Talk A cheap refractometer is designed to work so that you see light coming through the sample where the angle of incidence for rays going to the viewing point is less than the critical angle, and see reflected light from a blue screen where the angle of incidence is greater than the critical angle
How to use a refractometer in Kombucha - Homebrew Talk Most refractometer will give already %Brix readings for a solution of sugar in water, however Kombucha is far from being that A simplification of the finished Kombucha will be a solution of sugar, acetic acid and ethanol in water At this point a refractometer reading will not represent %Brix any longer
The Best Refractometer?: My experience with several popular devices Since getting into the hobby, I've been down the rabbit hole on salinity specific gravity measuring devices I've had the Hanna HI98319 Salinity Pen, a $20 Amazon White-Label refractometer, the Milwaukee MA887 digital refractometer, a VeeGee STX-3 now the Misco Aquar-H2O digital refractometer Years ago I even had the Instant Ocean Swing Arm

What refractometer to buy? - Reef2Reef The new Milwaukee MA887 Seawater Digital Refractometer encompasses 3 different types of user selected scales for the measurement of seawater providing for a much more precise evaluation Each scale is temperature compensated PSU - The newest type scale standard – Letters stand for Practical
Refractometer - what am I doing wrong? | Reef2Reef When using a refractometer that does not account for this effect, temperature changes can be a large source of errors Most liquid materials expand slightly when heated and shrink when cooled For a given material, light can pass through it more easily when it is expanded, so the index of refraction falls when materials are warmed
Huge discrepancy between refractometer and digital salinity meter I tested it with my refractometer: 1 025 I tested it with the digital salinity meter: 1 031 I tested the tank again: Refractometer: 1 024 Salinity meter: 1 025 When I test the refractometer with rodi water it shows a value probably around 0 995 When I test rodi water with the digital salinity meter it shows 1 000 What the heck is going on???
Refractometers And Salinity Measurement | Reef2Reef Refractometer Calibration Assuming that a refractometer is made correctly for the fluid it is intended to measure, the way to calibrate a refractometer is to put a liquid of known refractive index on it, and adjust the scale’s position by turning the calibration screw (Figure 3) until it reads correctly
Refractometer correction with sugar additions during ferment . . . The woodlandbrew tables, only go up to FG refractometer reading of 12, but my imperial stout is 17 5 Site does give formula used, so have option to calculate yourself But Vinolab - Alcohol from Hydrometer Refractometer tool does it for you Though it came up with z slightly higher ABV figure (by 0 5%) than a woodlandbrew table entry tried
