How It Works

A sensitive light sensor converts incoming light into an electrical signal, which is processed digitally to display illuminance in lux or foot-candles.

Agricultural Uses

Light is fundamental to plant growth. Measuring it provides useful information beyond visual estimates.

• In greenhouses: assess light transmission through the covering, determine the need for shade netting and evaluate how evenly light is distributed.
• For indoor plants: adjust light levels for shade-tolerant plants and assess the distance between plants and grow lights.
• In nurseries: check that seedlings receive enough light and help reduce stretching caused by low light.

Practical Features

• Wide range up to 200,000 lux.
• High accuracy for agricultural and engineering applications.
• Clear, easy-to-read display.
• Durable design for field work.
• Simple operation and fast response.
• Protective cap for the light sensor.

Suitable For

• Greenhouse owners.
• Ornamental plant nurseries.
• Hydroponic growers.
• Agricultural engineers.
• Electrical and lighting engineers.
• Grow light users.

Growing Tip

Whether you manage a greenhouse or supply shade netting, this meter provides measured light levels to support your decisions.
