The Thermohydrometer has the same features as the #7400 hydrometer, but also contains a thermometer that allows you to easily correct for the temperature of the sample when reading specific gravity.
Great product and price.
Easy to use, easy to read.........hope it last longer than my first one
I dropped a bucket on mine in the sink. Will be ordering asap. I have a spare without the thermometer. I hate it.I really like having the ability to adjust my readings based on the temp of the wort sample. Sure you can't test it right out of the mash. Just let it cool some while your brewing. Never been a problem. Best is right after you cool your wort so you have an accurate reading before you pitch the yeast.
