Handheld Quantum PAR Meter

LUYOR-3460PAR Handheld Quantum PAR Meter

Quantum Flux Meter 270 ° Rotatable Detector Measure Photosynthetically Active Radiation with External Waterproof Sensor and Telescopic Wand.

This PAR meter with external waterproof probe can be used to measure photosynthetically active radiation (PAR) in the air or underwater.

It measures PAR flux in wavelengths ranging from the 400 to 700 nm and measures up to 2,700 µmol/m²·s. The detector can rotate freely at 270 degrees, makes the measurement more accurate.
The external sensor is 1m long, the telescopic wand is 98cm long when pulled apart and only 21cm when folded, allows the user to place the sensor in hard to reach areas.
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.

The quantum meter is designed for PAR measurements in the air.

With External Waterproof Probe and Telescopic Wand, it can also be used for underwater measurements.
It can be measured from both sunlight and electric light sources to ensure plants are receiving proper light or photons for optimal health.
It is widely used for greenhouses, fields, growth chambers and aquatic environments including salt water aquariums and freshwater lakes and streams.
