Wireless Light Meters

Cast light on lighting.

Are you lighting up valuable assets like art in a gallery, exhibits in a museum, or plants in a greenhouse?

Then it’s essential to know how long these possibly priceless things should be under the lights, plus the intensity of the lighting, so you keep them protected and healthy.

ALTA® by Monnit Wireless Lux and PAR Light Meters can measure all your lighting systems in virtually any application or use case to ensure assets receive the exact light they require.

Our Lux (light in Latin) Light Meter is ideal for monitoring light-sensitive materials and assets used in pharmaceutical manufacturing, food ingredient production, art galleries, museums, facility management, and more.

The PAR (photosynthetically active radiation) Light Meter is perfect for connecting the performance of greenhouse and grow house lighting systems or even sunlight for outdoor agricultural operations to the Internet of Things.

Both Light Meters provide the actionable data you need to make the best lighting decisions for the critical assets that are most important to your organization.
