Description

Accurate and reliable

The PAR sensor measures the photosynthetically active radiation, which is capable of producing photosynthetic activity in plants and microorganisms.

It consists of a high accuracy silicon photodiode located inside an anodized aluminium casing. The cutting ring provides an excellent cosine response. Each sensor is calibrated against a secondary standard under natural light. It includes a 3 meters long cable.
