Three silver 2.2-inch dial hygrometers with glass faces

3 Pcs Mini Thermometer Hygrometer Silver 2.2 Inch

SKU CH-D5BJ-9FNDE

Three analog gauges track temperature from −20 °F to 120 °F and humidity with ±5 % accuracy, need no batteries, and mount anywhere

  • ColorSilver
  • Monitors temperature and humidity accurately with ±2 °C and ±5% precision
  • Dual-scale dial shows −30 °C to 50 °C and −20 °F to 120 °F
  • Aluminium-alloy case and glass lens resist corrosion for long-term use
  • No batteries needed — mechanical movement self-calibrates after settling
  • 28 in diameter fits wall, fridge, greenhouse, car or incubator

Three-piece silver hygrometer set

This pack contains three identical mini thermometer hygrometers finished in silver. Each unit combines temperature and humidity measurement in a single analogue dial that requires no batteries. The aluminium alloy case and glass lens give a clear, large scale for quick reading.

Indoor and outdoor monitoring for general use

The instruments suit home, office, greenhouse, refrigerator, incubator or vehicle mounting where a compact, battery-free gauge is convenient. They are not suited for applications that demand laboratory-grade precision, data logging, wireless transmission or calibrated certification.

±2 °C temperature accuracy

The temperature accuracy is specified as plus or minus 2 degrees Celsius, while humidity accuracy is plus or minus 5 percent. This tolerance decides whether the set meets the precision needed for a particular monitoring task.

Questions about this item

Will the 2.28 inch dial sit flush on a refrigerator door or does it need a separate magnet?

The 2.28 inch dial is 0.5 inch thick and made of aluminum alloy and glass; it has no built-in magnet so you must supply your own adhesive or hook for vertical surfaces.

How can I verify the gauge reads correctly after placing it in a room?

Let the unit sit in a stable spot for a few minutes; the dial then self-calibrates and should show temperature within ±2 °C and humidity within ±5 % of a trusted reference.

Does the pack of three include any mounting hardware or batteries?

The box contains only the three silver mini thermometer hygrometers; no screws, adhesives, or batteries are included because the mechanical movement needs no power.
