Six-pack hygrometer for multi-room monitoring

This Serundo Auto bundle supplies six identical mini thermometer-hygrometer units so you can track temperature and humidity in several locations at once. Each device shows both Celsius and Fahrenheit on a compact LCD and is powered by an included LR44 button cell with a spare. The pack suits homeowners, hobbyists or facility managers who need simultaneous readings in different rooms, enclosures or storage areas.

Dual-scale display and rapid refresh

The units switch between °C and °F at the press of a button and update measurements every 10 seconds. Stated accuracy is ±1 °C for temperature and ±3 % RH for humidity across a working range of 0 to 70 °C (32 to 158 °F) and 10 to 99 % RH. Two LR44 cells per meter are rated for up to 9 months of operation each, giving a long interval before battery changes are needed.

Simple placement, limited mounting options

No tools or wiring are required; just set each meter on a flat surface or attach it with the integrated stand. The small footprint fits terrariums, greenhouses, wine cellars or instrument cases, but there is no magnetic backing, adhesive pad or wall-mount hole supplied. Buyers who need permanent wall mounting or remote-probe sensing should look for a different form factor.

Questions about this item

How often will I need to replace the LR44 button cells in each of the six thermometers?

Each LR44 button cell powers a unit for up to 9 months, and a backup cell is included so you can swap it when the first one runs out.

What is the highest temperature the sensor can handle before it stops reading accurately?

The operating range tops out at 70 °C (158 °F); beyond that the device is outside its specified environment.

How much heat does each hygrometer generate when it runs continuously all day?

The units are passive sensors powered by tiny button cells, so they produce no noticeable heat during continuous operation.
