光合有效辐射仪/光量子计LUYOR-3460PAR
光合有效辐射仪LUYOR-3460PAR为植物光合有效辐照测量而设计。带有外部防水探头和伸缩棒，也可以用于水下测量。可以从阳光和电光源中进行测量，以确保植物接收合适的光或光子以达到更佳健康状态。光合有效辐射仪LUYOR-3460广泛用于温室，田地，生长室和水生环境，包括盐水水族馆，淡水湖泊和溪流。LUYOR-3460PAR光合有效辐射仪主要用于测量植物400-700nm波长范围内太阳光的光合有效辐射，被广泛用于农业气象和农作物生长的研究等领域。该传感器采用响应非常灵敏硅光探测器。并通过一个400-700nm的光学滤光器，来测量波长在400-700nm范围内的光合有效辐射。测量的的单位是μmolm2/秒.
光合有效辐射仪LUYOR-3460PAR特点：
这款可选配外部防水探头的PAR计可用于测量空气或水下的光合有效辐射（PAR）。
它可测量PAR通量，其波长范围为400至700 nm，更高可测量到2,700 µmol /m²·s。检测器可自由旋转270度，从而使测量更加准确。
外部传感器长1m，伸缩杆被拉开时长98cm，折叠时只有21cm，允许用户将传感器放置在难以触及的区域。
具有峰值保持功能和数据保持功能，易于在大型LCD屏幕上阅读。
由一块6F22 9V电池（不包括在内）供电，可连续使用约100小时。

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.
