Serundo Auto 4-pack thermometer hygrometer

This set includes four black digital thermometer hygrometers for indoor and outdoor monitoring. Each unit displays temperature in Celsius or Fahrenheit and humidity as a percentage. They suit home, office, garage, greenhouse, reptile terrarium, aquarium and other environments where simultaneous temperature and humidity readings are required.

Thermals noise and power draw

Each meter operates from a single LR44 button cell with a second cell supplied as backup. The sensors update readings every ten seconds across a working range of 0 to 70 degrees Celsius (32 to 158 degrees Fahrenheit) and 10 to 99 percent relative humidity. Temperature accuracy is ±1 degree and humidity accuracy is ±3 percent RH with no audible noise or external power needed.

Build fit and requirements

The compact devices require no wiring, mounting hardware or configuration; place them on any flat surface or attach with adhesive if desired. Two batteries per unit are included so the pack is ready to deploy immediately. They free up wall outlets and eliminate the need for a central display or data logger in simple monitoring tasks.

Questions about this item

How do I install the Serundo Auto hygrometer and what step is often missed?

Insert the included LR44 button cell and the spare LR44 into the battery compartment, then press the °C/°F button to select your preferred unit; the step many skip is removing the protective film from the LCD so readings are clear.

What maintenance will the 4-pack need and when?

Each unit runs on one LR44 cell with a spare provided; expect up to 9 months per cell, so swap to the backup around that time and keep extra LR44 cells on hand for the next change.

What is the first limit reached under continuous use?

The sensor updates every 10 seconds up to 70 °C or 158 °F and 99 % RH; sustained exposure beyond that temperature or humidity range is the first operating limit you will hit.
