Six-pack monitoring for tight spaces

This six-pack of mini digital thermometer hygrometers fits into jars, guitar cases, fridge shelves and grow tents where larger gauges cannot go. Each unit measures 1.89 in by 1.13 in by 0.66 in and weighs just .22 pounds, so a dozen locations can be tracked without crowding. The LCD screen measures 1.4 in by .66 in and updates temperature and humidity every ten seconds. Batteries are included for immediate use.

Steady readings across wide extremes

The sensors hold a temperature range of -58 to 158 degrees_fahrenheit and a humidity range of 10 to 99 percent RH under continuous operation. Accuracy stays within ±2 degrees for temperature and ±5 percent RH for humidity throughout the full span. The ABS housing and LCD remain functional in the same -58 to 158 degree environment, so the devices do not drift when left in a freezer or a heated greenhouse for weeks. No calibration is required after the first power-up.

Battery-powered independence limits placement

Because each hygrometer runs on its own included alkaline cell, there is no wiring, gateway or wireless protocol to manage. The trade-off is that data must be read visually on the 35.7 mm by 16.8 mm LCD; no logging, alerts or remote access are built in. Users who need historical graphs, smartphone notifications or a single dashboard for all twelve units will need a separate monitoring system. The mini form factor also means the display cannot show trend arrows or dew-point calculations.

Questions about this item

How much power does each unit draw when it runs continuously?

Each thermometer hygrometer uses a long-life alkaline button cell that powers the LCD display and the sensor circuit measuring every ten seconds; the cell lasts for months of continuous use.

What must I already have for these gauges to start working right out of the box?

Nothing extra is required; the six-pack ships with batteries already installed so you can place them immediately in a greenhouse, jar, guitar case or fridge.

Will the ±2 °F temperature accuracy and ±5 %RH humidity accuracy stay reliable next to older analog dial gauges I still use?

Yes, the digital sensor maintains its stated ±2 °F and ±5 %RH tolerance across the full -58 °F to 158 °F range, so readings remain consistent beside legacy instruments.
