## Description

The FG100sa Salinity Refractometer is a high-precision, dual-gauge instrument that accurately measures salinity (0 - 100 ppt) and specific gravity (1.000 - 1.070 S.G.) in water. Equipped with an Automatic Temperature Compensation system (ATC).

Review: Excellent quality - Works perfectly and easily allows me to verify and track my salinity. Takes a few seconds.
Review: ⭐️⭐️⭐️ Works, but accuracy and consistency depend on calibration - This refractometer does the job, but it’s not quite “set it and forget it.” With proper calibration, it can give reasonably accurate readings, and the automatic temperature compensation is helpful when conditions change slightly. That said, accuracy really depends on frequent recalibration. I found that if you don’t calibrate often, readings can drift, which defeats the purpose if you need consistent measurements (especially for aquariums or salinity-sensitive setups). The adjustment screw is a bit sensitive, so small turns can cause noticeable changes. Build quality is decent but not premium. It feels fine for occasional use, but I wouldn’t rely on it for professional or lab-level accuracy. The optics are clear enough, though focusing takes a little patience at first. Pros: • ATC feature helps with temperature changes • Easy to use once calibrated • Compact and portable • Good for basic or hobby-level use Cons: • Needs frequent recalibration • Adjustment screw is overly sensitive • Not ideal for precision-critical applications Overall, this is okay for hobbyists who don’t mind double-checking calibration, but if you need high precision or long-term consistency, you may want to invest in a higher-end model.

### ⭐⭐⭐⭐⭐ Reliable
*by D***L on March 28, 2023*

This is the best refractometer for the money. Unlike cheaper ones, it will hold calibration a month or more. Worth every penny.
