Two-Pack Indoor Climate Monitor

The KJCOOSWI two-pack supplies a black and a white digital hygrometer thermometer for simultaneous monitoring of two rooms. Each unit measures temperature from -20 to 70 degrees Celsius and humidity from 10 to 99 percent relative humidity. The devices suit bedrooms, nurseries, wine cellars, greenhouses or any indoor space where climate awareness matters.

Battery Power and Mounting Flexibility

Two AAA batteries per unit are included and support roughly 18 months of operation before replacement. AAA cells are easier to source and install than CR2032 alternatives. A built-in stand, a magnet and a hanging slot give three placement options on a table, a metal surface or a wall without extra hardware.

Readings Updated Every Ten Seconds

The display refreshes every 10 seconds and shows a comfort trend labelled DRY, COMFORT or WET based on the current humidity level. Temperature accuracy is within ±1 degree Celsius and humidity accuracy within ±5 percent RH. No backlight is fitted so readability depends on ambient light.

Questions about this item

How often does the sensor refresh its reading?

The unit samples temperature and humidity every 10 seconds and updates the LCD accordingly.

Does the display generate noticeable heat or noise during continuous operation?

No, the passive LCD runs silently and produces no measurable heat while the device monitors conditions around the clock.

Which batteries are needed to start using the two monitors right away?

Four AAA cells are included — two per unit — so the hygrometers work immediately after unboxing.
