Quantum PAR Meter Full-Spectrum PPFD Tester DANOPLUS DP-355

Description

Product Overview

The Quantum PAR Meter by DANOPLUS is a high‑precision instrument engineered to quantify photosynthetically active radiation (PAR) across the full 400‑700 nm spectrum. With a measurement range of 0 to 5000 µmol/m²·s, it captures the exact light energy available for photosynthesis, enabling growers and scientists to fine‑tune lighting regimes for optimal plant health. The device features a robust LCD display, intuitive one‑button operation, and a durable housing that resists dust and moisture, making it suitable for both laboratory benches and field conditions. Calibration is factory‑set and remains stable over the product’s lifespan, ensuring consistent data integrity. The meter’s compact dimensions (7.48 × 3.7 × 1.85 in) and lightweight build (8.47 oz) allow effortless transport between greenhouses, growth chambers, and outdoor test sites.

Usage

Whether you are managing a commercial hydroponic farm, conducting academic research, or evaluating lighting fixtures for a vertical farm, the Quantum PAR Meter provides actionable insights. Place the sensor head at canopy level to record real‑time PPFD values, then compare readings across different growth stages or lighting configurations. The built‑in record function stores up to 100 data points, enabling trend analysis without the need for external logging equipment. Its tripod socket (compatible with standard 1/4‑inch mounts) ensures stable positioning during prolonged measurements, reducing user fatigue and improving repeatability. The meter operates on a rechargeable lithium‑ion battery that delivers up to 12 hours of continuous use, supporting on‑the‑go assessments in remote or large‑scale operations.

FAQ

What does PAR mean and why is it important for plant growth?

PAR stands for Photosynthetically Active Radiation, which is the range of light wavelengths (400‑700 nm) that plants use for photosynthesis. Measuring PAR helps growers understand how much usable light their crops receive, allowing them to adjust lighting intensity, spectrum, and duration to maximize photosynthetic efficiency and yield.

Can the meter be used for both LED and HPS lighting systems?

Yes. The Quantum PAR Meter is calibrated to detect the full 400‑700 nm spectrum, making it compatible with LED, high‑pressure sodium (HPS), metal‑halide, and other horticultural lighting technologies. It accurately reports PPFD regardless of the light source, enabling direct comparisons between different fixtures.

How often should I calibrate the meter?

The device comes pre‑calibrated from the factory and maintains its accuracy for years under normal operating conditions. Calibration checks are recommended only if the meter has been exposed to extreme temperatures, physical shock, or after any major repair. DANOPLUS provides calibration services upon request.

Is the recorded data exportable for analysis?

While the meter stores up to 100 readings internally, data can be transferred manually by noting the values or using the optional USB interface (sold separately). This allows integration with spreadsheet software or specialized horticultural analysis tools for deeper insight.

What battery life can I expect during continuous use?

The built‑in lithium‑ion battery provides approximately 12 hours of continuous operation on a full charge, which is sufficient for a full day of field measurements. Recharging takes about 2 hours, and the device includes a low‑battery indicator to prevent unexpected shutdowns.
