Digital hygrometer without probe

Digital Thermometer & Hygrometer 2-in-1 – Precise Measurement in a Compact Form

A small yet highly functional measuring device, perfect for formicariums and terrariums. It allows simultaneous monitoring of temperature and humidity – two key parameters in ant keeping and care of other terrarium animals.

External dimensions: 48 mm × 29 mm

Application:

This device is ideal for formicariums, where precise control of the microclimate directly affects the health and activity of the colony. Optimal humidity levels vary depending on the ant species:

• Messor barbarus: 40–50%

• Lasius niger: 50–60%

• Exotic species: up to 100%

Why is it worth choosing?

• Compact size – fits easily into small spaces

• Clear 3-digit temperature display – more precise than 2-digit models

• Dual battery pack – works on a single AG13/LR44 battery, but includes two batteries for longer life and more stable power

• Fast response and good measurement resolution

• Flexible installation – can be mounted or used freely; fits neatly into rectangular openings

• Dual parameter reading – full control over environmental conditions in one device

Usage guidelines:

• Do not place directly near heating or cooling sources

• Avoid direct sunlight and steam exposure

• Do not breathe onto the sensor – moisture from breath can affect readings

• Keep the device clean; do not use in dusty environments

Humidity measurement accuracy: ±5–10%
