The Environmental Meter is suitable for continuous monitoring of oxygen content, temperature, and relative humidity in indoor areas. Typical applications include offices, laboratories, technical rooms, storage areas, schools, greenhouses, and any environments where reliable indoor air monitoring is required.

The device measures oxygen content in the range of 0 ... 30% with a resolution of 0.1%, temperature from -9 ... 55°C with a resolution of 1°C, and relative humidity from 0 ... 100 % with a resolution of 0.1%. A 3.5-inch LCD colour display ensures clear and easy-to-read presentation of the measured values. The Environmental Meter offers several views such as real-time values, trend display and history display, as well as automatic switching between displays. The device has an integrated alarm function with visual traffic light indication and fixed threshold values for rapid assessment of air quality.

The Environmental Meter also shows the date and time directly on the display. For long-term measurements, the Environmental Meter has an integrated data logger with large memory, adjustable interval and rechargeable lithium battery for flexible use. The stored measured data can be viewed directly on the device; reading out or transferring the memory to external systems is not yet possible. Overall, the Environmental Meter combines precise measurement technology, clear presentation and extensive recording functions in a compact device.
