APM130 PAR Meter Digital Quantum PPFD Sensor Light Meter with Plants Data Recording

Optimize light intensity and maximize crop growth with the APM130 Digital PAR Quantum Light Meter. Designed for professional horticulturists, indoor growers, and researchers, this precision Photosynthetically Active Radiation (PAR) meter measures real-time Photosynthetic Photon Flux Density (PPFD) across the vital 400nm to 700nm spectral waveband. Equipped with a high-accuracy, waterproof quantum sensor probe on a flexible extension cable, it allows you to capture precise light readings directly at the plant canopy level without casting shadows from the hand unit. Featuring built-in data logging capabilities, clear backlit digital display, and multi-unit display functions, the APM130 helps you optimize grow light height, tune LED light spectrum distribution, and prevent light burn or under-illumination across all plant growth stages.

Key Features

• Precision PAR & PPFD Measurement: Accurately measures Photosynthetically Active Radiation ($\mu\text{mol}/\text{m}^2/\text{s}$) to optimize indoor grow lighting.

• Waterproof Quantum Light Sensor: Submersible sensor probe allows reliable PPFD measurements under high-humidity greenhouse mist or underwater in aquatic setups.

• Integrated Data Recording & Memory: Built-in data logging function records PPFD readings over time for tracking light distribution and daily light integral (DLI).

• Flexible Extension Probe Cable: External sensor wand prevents body shadows from altering light readings during canopy testing.

• Clear Backlit Digital LCD Display: High-definition screen displays real-time PPFD, peak values, and battery status clearly under intense light or dark conditions.

Why Choose Our APM130 Digital PAR Meter

Relying on generic lux meters or lumen apps causes inaccurate light measurements because plants respond strictly to quantum photon count (PPFD) rather than human visual brightness. Over-illuminating wastes electricity and causes light burn, while under-illuminating reduces yield weight and slows growth. The APM130 PAR meter combines laboratory-grade quantum sensor accuracy, waterproof canopy probe flexibility, integrated data logging memory, and rugged field durability—giving your indoor cultivation, LED grow light calibration, and greenhouse management an instant professional upgrade.
