The Milwaukee digital BRIX refractometer is temperature compensated with a 0 to 85 percent BRIX range and +/- 0.2 percent accuracy. It is easy to use with simple two button operation and fast with a response time under 2 seconds. Maintenance is a breeze also with an easy-to-clean sealed flint glass prism and stainless steel well.DESIGN FEATURESFast, accurate results with digital dual level LCD readout. Easy measurement with just 2-3 drops of sample needed and results less than 2 seconds. Simple one-point calibration using distilled or deionized water. Easy to clean, stainless steel sample well with unit rated to IP65 as "dust tight" and protected against water jets. Battery percent level indicator with automatic shut-off (batteries included). Ideal for winemakers, brewers, fruit and vegetable growers, maple syrup producers, and food producers. The measurement technique and temperature compensation employ methodology recommended in the ICUMSA Methods Book (Internationally recognized body for Sugar Analysis).
Using a timer to automate your lighting adds convenience and encourages productive growth with consistent hours of light. Timers are also essential for many hydroponic system applications.
