Introducing the Phantom Photobio Advanced PPFD Quantum PAR Meter provides accurate and cost-effective measurement for any light source used in horticultural applications such as use with LED Grow Lights.

PAR meters are an essential piece of equipment when growing indoors. You wouldn't guess your nutrient EC or environment. Why risk not knowing what lighting levels you're running? using the correct light levels can also improve yields by maximising photons per square meter

Wide PAR Range

The Advanced Quantum PAR meter is designed to measure PAR (Photosynthetically Active Radiation) flux in wavelengths ranging from 400 to 700nm. There is a positive proportional relationship between the number of photons absorbed in 400 to 700nm band and the rate of photosynthesis, important for maximizing crop yield.  

Included With The Kit

Complete with compact main unit, remote sensor, two connection cables (short-coiled & 12’ long-straight), AAA batteries and protective carrying case.  Conveniently store up to 99 measurements for easy reference while adjusting light fixture height, dimmer setting and other environmental changes throughout each phase of growth.

Quality & Warranty

Phantom has a long-standing track record of providing reliable, high-performance products within the horticultural equipment industry. All the Photo-bio par meters come with a 1 Year warranty.

• Compact, portable meter with highly accurate remote quantum sensor
• Simple and easy-to-use operation, with storage of up to 99 readings
• Ideal for grow tent, greenhouse and commercial grow applications
• Compatible with modern sole-source and supplemental LED fixtures, high-pressure sodium (HPS) DE grow lights, as well as any traditional indoor grow light source

Frequently Asked Questions?

Q. What is a PAR meter?

A. A PAR PPFD meter is a device used to measure the amount of photosynthetically active radiation (PAR) that plants receive. PAR refers to the range of light wavelengths from 400 to 700 nanometers that plants use for photosynthesis.

Q. What does a PAR meter do?

A. In essence, a PAR PPFD meter helps in assessing the light conditions for plant growth by measuring the intensity of usable light. This is particularly important in controlled environments such as greenhouses, indoor grow rooms, and agricultural research, where optimising light conditions can significantly impact plant health and productivity. PAR meters typically consist of a sensor that detects the light intensity and a display unit that shows the PPFD value.

Q. What does PPFD Mean?

A. PPFD stands for Photosynthetic Photon Flux Density, which quantifies the number of photons in the PAR range that hit a square meter per second (measured in micromoles per square meter per second, or µmol/m²/s).

Q. Why use a PAR meter?

A. Using a PAR meter is essential for optimising plant growth, particularly in horticulture, agriculture, and plant research. These meters measure the light available for photosynthesis, ensuring plants receive the right amount of light to promote healthy growth and maximise yields. In indoor growing environments, PAR meters help adjust artificial lighting to provide the correct intensity and distribution, ensuring plants get uniform and adequate light without wasting energy. This consistent light level improves crop quality and quantity, affecting aspects like smell, flavour and density.
