Handheld Quantum PAR Meter Quantum Flux Meter 270 ° Rotatable Detector Measure Photosynthetically Active Radiation for Agriculture Greenhouses Growth

• This PAR meter is used to measure photosynthetically active radiation (PAR) in the air. If you also need to measure underwater PAR, there’s another set for sale.
• With integrated quantum sensor, it measures PAR flux in wavelengths ranging from the 400 to 700 nm and measures up to 2,700 ?mol/m??s.
• The detector can rotate freely at 270 degrees, makes the measurement more accurate.
• Features with peak hold function and data hold function, easy to read on large LCD screen.
• Powered by one 6F22 9V battery (not included), can be used continuously for about 100 hours.
