Description of ๐Ÿ”ฌ Vee Gee Scientific STX-3 Handheld Refractometer with Salinity Scale - 0-100 Range, +/-1.0 Accuracy, 1.0 Resolution

Handheld portable refractometer for measurement of salt concentration in parts per thousand (PPT) (0 to 100%) and specific gravity (SG) (1.000 to 1.070) of seawater in the 10 to 30 degrees C temperature range. Automatic temperature compensation (ATC) for immediate and accurate calibration readings, regardless of ambient temperature. Ambient light illuminates the scale; no additional power source is required. Durable metal and rubber outer shell with a telescope-shaped, streamlined design (40 x 40 x 185mm), a rubber grip to guard against hand heat for accurate measurements, and a non-roll stand to protect against damage. Optical glass prism mounted in all-metal housing for quick temperature equilibrium between sample and prism.

Worth the money - test, measure and verify

There are cheap refractometers and there are Vee Gee refractometers. The cheap ones are very light and frankly cheap made out of plastic and have a screw adjuster for size adjustment. The Vee Gee is a solid instrument with a glass optical prism and a very nice ring for easy calibration adjustments. If you're getting a refractometer for your saltwater aquarium (and don't want to rely on inaccurate swing arm hydrometers), you should definitely get the Vee Gee. This one is definitely worth theโ€ฆ

Pros
  • It's amazing
Cons
  • Some errors

Perfect! - Test, measure and verify

This refractometer is amazing! I have a reef aquarium with a $150 wartfrog, a $950+ coral and a Maxima clam, so I need to keep the water parameters as close to ideal as possible. Every time my water level goes down I don't know if I need to add more distilled H2O due to evaporation or more saline water due to water being collected by my protein skimmer. With this handy device, all you have to do is put a few drops of salt water on the lens and get accurate readings. This refractometer is alsoโ€ฆ

Pros
  • Certified
Cons
  • Cable is shorter than others

Accurate, stable readings, calibration!

I have a Neptune Systems APEX controller for my reef tank that measures and reports salinity (conductivity) in real time, but I still rely on the VEE Gee STX-3 refractometer as the last word in this regard the salinity is really there. I check the refractometer calibration before each use with Aqua Craft Products refractometer calibration solution and the refractometer readings are right within the standard and I have not had to adjust the calibration yet. This gives me confidence that theโ€ฆ
