How To Measure Specific Gravity Of A Beer Using A Hydrometer – A Step-By-Step Guide
Precision is important when working in a lab. Specific Gravity Specific gravity is the ratio of a specific plastic substance’s density compared to the density of water. A hydrometer for specific gravity is also a good and easy way to measure it. Below is a step by step guide on how you can correctly use a hydrometer. The Equipment You Will Need: MVTex
A hydrometer – You can observe the manufacturer’s brewing instructions by using a hydrometer to measure the temperature.
Step-by-Step Guide:
Sample Solution Preparation
Begin by pre-visioning the liquid sample that you want to measure the specific gravity of. Make sure it is devoid of bubbles and impurities, since these can impact readings. If necessary, you can even use a lab centrifuge machine to separate particles or contaminants.
Adjust the Temperature
Because temperature influences density, specific gravity is generally measured at a standard temperature (typically 20°C). Heat by agitation into the desired temperature with a lab water bath and prove the accuracy with a laboratory thermometer.
Transfer the Sample
Transfer the sample to a clear, dry cylinder or jar, large enough to permit free floating of the hydrometer.
Insert the Hydrometer
Carefully place the hydrometer for specific gravity into the sample. Make sure it doesn’t touch the container and it is floating free.
Read the Measurement
Wait until the hydrometer is settled. Read the level at the meniscus (the curve observed in the surface of the liquid) at eye level. Read the number where the surface of the liquid touches scale.
Adjust for Temperature (if you need to)
Correct the hydrometer reading if the difference between the calibration and measurement temperature is significant, based on the reading from the laboratory thermometer. There is a correction chart included with most hydrometers.
Record and Clean
Note specific gravity and clean all equipment, including the hydrometer, thermometer and container. A cork borer or other such device may usefully be employed to make orifices of this kind in soft material plugs if sample processing is necessary.
