Product description

Multifunctional Indoor Air Monitoring: Keep track of changes in your surroundings with targeted indoor sensing and a clear main reading. Real-time temperature and humidity add useful room details to the same device. A useful addition to homes with kitchen or heating appliances, with placement guided by the instructions for your space.
85 dB Sound and Visible Signals: You do not have to keep watching a screen to notice a triggered event. The device pairs an 85 dB sound with a visible signal to draw your attention, adding an audible cue to the information on the display. Separate front-facing status lights also make it easy to check the device, so routine use stays straightforward.
Clear LCD with Readings at a Glance: The main sensor reading is centered on the LCD, with temperature above and humidity below. This clear layout keeps each value easy to find without switching screens. Real-time room readings also help you decide whether to adjust a thermostat or humidifier, bringing practical value to a quick daily check.
Plug-and-Play with Easy Testing: A useful device should fit into your day without turning setup into a project. The direct plug-in design needs no hardwiring and leaves tables and shelves free for everyday essentials. Use a suitable powered outlet, follow the startup steps and keep it plugged in during use. The test button makes routine checks easy to start.
Placement Made Clear: For lighter-than-air substances, install within 11.8 in (30 cm) below the ceiling. For heavier-than-air substances, install within 11.8 in (30 cm) above the floor. Keep the device 3.3-13.1 ft (1-4 m) from the source. Identify the target type before choosing the height, and use a suitable powered outlet throughout operation.
