## Overview

The Universal Specific Gravity Kit transforms your electronic bench scale into a high-precision density measurement tool. Featuring 0.01g accuracy compatibility, a 3-way adjustable beaker assembly, and a full suite of accessories—including a 300-mineral SG reference table—this kit streamlines specific gravity testing for minerals, gems, and industrial solids. Designed for scales with a minimum 50g capacity and 3-inch platform, it offers fast, reliable, and universally adaptable performance for professionals demanding exactness.

## Description

Use this kit with _your_ Electronic Bench Scale to measure the Specific Gravity or Density of Minerals, Gems, Industrial Materials, and any solid, for that matter. Please note that the Kit does not include the Scale, but this SG kit is "Universal" in that it is compatible with most any full size, Bench or Lab scale. It is adjustable in 3 different dimensions for Scales of varying height, depth, and width. The Kit includes everything you need to measure Specific Gravity, except for the Scale and the Water. Note: There are two versions/sizes of this kit. Choose our "Carat Scale" version of the kit, instead, for use with small, pocket carat scales (search SGK-C).

## Features

- This "Electronic Scale" method/device is the best overall for Specific Gravity measurement. It is very accurate, providing that the Scale you use it with is sensitive enough, while the measuring process is quick and easy, overall.
- To operate, just weigh your sample in "Air" (which is the same as weighing it on the platform of your Scale), and then weigh the sample in "Water." Then calculate SG by dividing the difference between the heavier Weight in Air and the lighter Weight in Water, into the Weight in Air. A simple Worksheet is provided for that purpose.
- Kit contains 3-way adjustable Beaker assembly, Weighing Pan assembly, Aluminum Stick reference weight (SG=2.70), Tweezers, Illustrated Instructions, Worksheets, and Table of 300 Minerals sorted by Specific Gravity.
- Your Scale must have minimum Capacity of 50 grams, protruding Weighing Platform at least 3" across, openable or removable draft shield/lid for access from front and 1 side, and Tare function to Zero out Scale. This kit uses a 100mL Beaker as a water container, with approximately a 2.2" inside diameter. The tared weight of that portion of the kit that actually sits on top of the scale's weighing platform is 26 grams.
- SG accuracy depends on Readability or Minimum Weight spec of the Scale you use with the SG Kit. Rule of thumb is Readability x factor of 50, so a Scale with Readability of .01g will give accurate SG on items weighing down to .5g (.01 x 50).

## Questions & Answers

**Q: How are specimens attached? Can I weigh multiple beads at once?**
A: Specimens are attached by simply laying them on the Weighing Platform of the Scale (for the "Weight in Air"), and on the Underwater Weighing Pan (for the "Weight in Water").  In both cases, the specimens are "attached" only by the force of gravity.Yes, you can weigh multiple beds at once.  Your SG measurement would be valid, however, only if all of the beads in the weighing sample are of the same species.

**Q: Does this come with a chart for the different S.G. of karated gold?**
A: No, it comes with a table of 300 Minerals and Gem Minerals, sorted by Specific Gravity, along with other properties of minerals.  You should be able to find a SG of Karated Gold chart online.

**Q: What is the weight of the kit (my scale goes up to 314 g) ? thank you**
A: The tared weight of that portion of the kit that actually sits on top of the scale's weighing platform is 26 grams.

**Q: Could you use a 500 ml beaker with a 5 in diameter instead of the 100 ml one in the picture?**
A: The short answer is Yes, but since the Beaker Holder in our SG Kit is sized for the smaller 100mL beaker, you would have to improvise your own 500mL Beaker support.  Beyond that, the Tri-Wire support for the Underwater Weighing Pan, which sits on the platform of the Electronic Scale, surrounds the Beaker Holder, without touching, and is sized for our 100mL Beaker Holder, so if you were to still use our Tri-Wire support, your improvised Beaker Holder would have to fit inside that.  With all that in mind, you might be better off using the Ohaus Cent-O-Gram 311 or Dial-O-Gram 310 Mechanical Beam Balance, in combination with our Specific Gravity Kit for that Ohaus Balance, but substituting your larger 500 mL Beaker.

Really nice item! I love it!

### ⭐⭐⭐⭐⭐ Well built
*by R***R on September 4, 2023*

Easy to use even for beginners. Got an extra 3 year warranty for this item. Gives accurate measurements. When combined with a loupe, spectrascope, dichroscope and refractometer you can identify any gemstone. I also have a UV light and a chealsea filter for Emerald and others. I also use the presidium gem tester II. I bought a special scale to go with it.
