Review on 🔬 Milwaukee MA887 Digital Salinity Refractometer with Automatic Temperature Compensation, Yellow LED, 0 to 50 PSU, +/-2 PSU Accuracy, 1 PSU Resolution (color may vary) - Enhanced SEO by Jamie Lundgren

Exactly what it says, accurate refractometer. Compared to my analog refractometer, it is very stable and provides accurate room temperature readings, which is critical for automatic temperature calibration. The device feels very solid and the way the bottom battery compartment opens is waterproof. I like the fact that the device does a little "self-test" when you turn it on, which shows the remaining battery life, along with a few other screens. I really like this device, for those who want to review things like me, you will be very satisfied. Because the device uses distilled water to calibrate every time you use it. Any distilled water will do. This is one I recommend with confidence, a great investment in reef aquarium protection and maintenance!
