Digital Hygrometers | Color-coded 6-Pack Digital Hygrometers

Humidity control is guesswork until you measure it. These are six mini digital hygrometers with LCD displays, small enough to sit inside a jar, a case or a humidor and read the temperature and relative humidity in there rather than in the room. $29.99 for six.

A HYGROMETER, NOT A HYDROMETER

Worth clearing up, because the two get mixed up constantly. A hygrometer measures humidity in the air. A hydrometer measures the density of a liquid, for brewing and batteries. If you are here to check the humidity inside a jar or a humidor, a digital hygrometer is the one you want.

SMALL ENOUGH TO GO INSIDE THE CONTAINER

That is the difference from a room monitor. These fit inside storage jars, sealed bags, pouches, cases and humidors, so you read the air that is actually around your herbs. A wall unit cannot tell you that.

WHAT IT READS, AND HOW CLOSELY

Humidity from 10% to 99% RH, accurate to within 5% RH. Temperature from -58F to 158F, accurate to within 2F, displayed in Fahrenheit. That resolution is fine for keeping a jar near 62% and for catching it when something has drifted.

A CLEAR LCD YOU CAN READ AT A GLANCE

The display is legible from across a room, so checking a shelf of jars does not mean picking each one up. Two LR44 button cells are included and already fitted.

SIX UNITS, THREE COLORS

The 6 pack comes in three colors, which is more useful than it sounds. Color-code by contents or by container and you can tell at a distance which reading belongs to what.

WHERE ELSE PEOPLE USE THEM

Humidors, wine cellars, guitar and violin cases, reptile enclosures, cars, offices and grow spaces. Anywhere sealed, where the humidity matters and the room reading tells you nothing useful.

$29.99 FOR SIX

Six units, batteries included. Premium quality, without the premium price tag.

NOW DO SOMETHING ABOUT THE NUMBER

A reading only helps if you can act on it. The 2-Way 62% Humidity Packs hold 62% in a jar, the Humidifying Stones add moisture and recharge with water, and stash jars give you something worth sealing in the first place.
