The 4 in 1 Multi-Function Environmental Meter includes sound sensor, | |
The 4 in 1 Multi-Function Environmental Meter combines a noise analyser, a light meter, a thermometer and a relative humidity. The Environmental Meter is especially suited to educational settings with the aim of measuring all 4 parameters and can also be used in both a professional setting or at home. The Environmental Meter with all its sensors, comes in a light carrying case and is both easy and quick to use. Test environmental conditions directly. | |
Note: the Environmental Meter is for taking orientative measurements. If you wish to take high precision measurements, then you should choose a specific measuring instrument that corresponds to the specific parameters. |
