How to Test the Proof of Alcohol Proof" is a measurement of how much alcohol is in a liquid. The term was originally used before there was a reliable way to accurately determine alcohol content. In the original proving test, a small amount of the liquid to be tested was poured on a bit of gunpowder and exposed to flame. If there was enough alcohol in the liquid, it would burn and eventually ignite the gunpowder. Liquid with too little alcohol would simply wet the gunpowder and prevent it from igniting. Modern precision thermometers and hydrometers allow for much more accurate estimations of alcohol content. Instructions 1 Examine the side of your hydrometer, or the instructions that came with it, to find the temperature for which it is calibrated. Most hydrometers are calibrated for 20 degrees Celsius (68 degrees Fahrenheit). 2 Use a thermometer to find the temperature of the alcohol you intend to test. Warm or cool the alcohol to the temperature for which your hydrometer is calibrated. The closer to the correct temperature the alcohol is, the more accurate you results will be. 3 Pour the alcohol into a tall thin vessel, such as a tall drinking glass, until it is close to full. Slide the hydrometer into the glass without touching it to the sides. Gently swirl the hydrometer to dislodge any bubbles that may have clung to its sides or bottom. Since alcohol is lighter than water, the hydrometer sinks deeper into liquids of higher alcohol content. Read the measurement on the side of the hydrometer even with the surface of the alcohol. alcohol tester alcohol tester alcohol breath tester Dreambox dm8000 hd pvr dreambox dm7025 Dreambox dm800 HD Se with WiFi Sunray4 DM800 HD SE Dreambox dm800 hd pvr dreambox dm500 hd power inverter car power inverter solar power inverter high power inverter 12v power inverter power inverters power supply grid tie power inverter pure sine wave power inverter pure sine wave inverter sine wave inverter solar power inverters Dreambox satellite receiver Vu+ Ultimo Dreambox dm 8000 hd pvr satellite receiver Dreambox dm600 PVR satellite receiver VU+ Solo2 Twin Satellite Receiver Dreambox dm500S satellite receiver DreamboxDM 500 OEM Dreambox DM500C Dreambox DM500C OEM Dreambox DM500S OEM Dreambox DM500Si Silver Dreambox dm500Si black Dreambox dm 518S Dreambox DM500T AzBox HD Elite AZBOX HD PREMIUM Dreambox dm500S satellite receiver DreamboxDM 500 OEM Dreambox DM500C Dreambox DM500C OEM Dreambox DM500S OEM Vu+ SOLO Single Tuner HD PVR Vu+ DUO Twin Tuner HD PVR ORTON HD X403P AZbox HD Premium Plus AZbox Bravoo HD AZBOX Ultra HD AZBox HD Elite AZbox EVO XL AZ America s810b AZ America S812 AZ America S900 HD Wifi bridge for Dreambox E Book reader Tablet PC Strong SRT 4669X satellite receiver Strong Mini HD PVR Strong SRT 4663X Strong SRT 4653X Dreambox dm800 HD SE satellite receiver gold leaf jewelry gold leaf earrings silver leaf pendant silver leaf jewelry Dreambox dm 800 hd pvr Dreambox dm500S satellite receiver DreamboxDM 500 OEM Dreambox DM500C Dreambox DM500C OEM Dreambox DM500S OEM Dreambox DM500Si Silver Dreambox dm500Si black Dreambox dm 518S Dreambox DM500T AzBox HD Elite AZBOX HD PREMIUM Skybox S12 HD PVR satellite receiver Skybox S11 HD Pvr satellite receiver Skybox S10 HD PVR Skybox S9 HD PVR Dreambox dm800 HD SE satellite receiver Dreambox dm 800 hd pvr Dreambox dm500S satellite receiver DreamboxDM 500 OEM digital breath alcohol tester alcohol testers personal alcohol tester breathalyzer alcohol tester alcohol tester breathalyzer alcohol tester kopen alcohol tester frankrijk breath alcohol tester alcohol content tester alcoholtester alcohol breath testers breathalyzer alcohol test alcohol breathalyzer alcohol breath test blood alcohol tester alcohol tester keychain portable breathalyzer breathalyzer for sale personal breathalyzer alcohol tests alcool tester alcohol tester frankreich digital alcohol tester alcohol breath alcoholtesters breathaliser bac tester alcohol detector
