Electronic environment thermometer Bresser Optics 7000020CM3000

The BRESSER Temeo Hygro Quadro is an electronic environment thermometer that monitors temperature and air humidity at four different locations: one master station and three remote sensors. The master station receives wireless data from the sensors and also records temperature and humidity on site. The compact, battery-powered design makes it suitable for placing in rooms, basements, children's bedrooms or on terraces to keep track of environmental conditions.

Advantages

The system allows simultaneous monitoring of temperature and relative humidity at up to four points, with wireless transmission from three remote sensors to the master station over 433 MHz. The device supports temperature readings in Celsius and Fahrenheit and runs on AAA (LR03) batteries, enabling flexible placement without the need for mains power. The compact dimensions and lightweight construction make installation and relocation simple.

Suitable for

• Monitoring basement or cellar humidity to detect mold risk
• Checking temperature and humidity in children's bedrooms
• Measuring conditions on terraces, balconies and patios
• Comparing indoor and outdoor temperatures at multiple locations

Place the master station in a central location where you can read the display and position the three sensors at the sites you want to monitor. The sensors transmit temperature and humidity readings to the master station over 433 MHz; the master station also measures the local environment. Refer to the supplied manual for details on pairing sensors and replacing batteries.

Recommendations

Place sensors away from direct sunlight, heat sources or draughts for accurate temperature and humidity readings. Replace batteries when signal or measurements become unstable and verify correct sensor pairing after battery changes.
