PAR Meter 2 in 1 PAR DLI Meter with Data Logging, Record and Export 5 Years of Data, 400-700nm PPFD Meter Sunlight Meter Measure PPFD and DLI (Daily Light Integral), Light Measurement Tool for Plants

Description

Product Overview

The DANOPLUS PAR Meter 2-in-1 is engineered to deliver accurate photosynthetic photon flux density (PPFD) and daily light integral (DLI) readings across a broad spectral range of 400‑700 nm. Housed in a compact 2.76 × 2.76 × 1.18 inch enclosure weighing just 3.52 oz, the device combines a high‑resolution LCD display with a robust IP65 waterproof rating, making it suitable for both greenhouse benches and field trials. The meter supports a measurement range of 0‑5000 µmol m⁻² s⁻¹, and its built‑in real‑time clock records date and time for each data point, ensuring traceability. A 1/4‑inch screw mount and an optional soil rod accessory allow flexible positioning on plant canopies, light fixtures, or soil surfaces. The device also features a power‑saving mode that blanks the screen after three minutes of inactivity while continuing to log data, extending battery life for prolonged deployments.

Usage

Designed for professional growers, researchers, and hobbyists, this meter excels in a variety of environments. In indoor vertical farms, it helps fine‑tune LED spectra to match crop‑specific light requirements, reducing energy waste and boosting yields. Outdoor gardeners can deploy the waterproof unit on sunny patios or shaded greenhouse aisles to monitor natural sunlight fluctuations throughout the day. The data‑logging capability is especially valuable for long‑term studies, allowing users to export five years of accumulated DLI data via USB‑C to a CSV file for analysis in spreadsheet software. Whether you are tracking light exposure for seedlings, flowering stages, or mature fruiting plants, the PAR Meter provides the granularity needed to make informed decisions about supplemental lighting, shading, or plant placement.

FAQ

How does the meter calculate DLI?

The device integrates PPFD values over a 24‑hour period, automatically converting the cumulative photon flux into Daily Light Integral (mol m⁻² day⁻¹). The internal clock timestamps each measurement, so the DLI reflects actual light exposure for the selected day.

Can I use the meter with both LED and HPS lighting?

Yes. The sensor’s spectral response covers 400‑700 nm, which includes the output of most LED grow lights as well as high‑pressure sodium (HPS) fixtures. This makes it a versatile tool for mixed‑lighting setups.

What is the battery life during continuous logging?

When operating in continuous logging mode with the screen dimmed, the built‑in rechargeable lithium‑ion battery can run for up to 30 days. The power‑saving feature further extends this by turning off the display after three minutes of inactivity.

How do I export the logged data?

Connect the meter to a computer via the supplied USB‑C cable. The device appears as a removable drive, and the data is stored in a CSV file that can be opened with Excel, Google Sheets, or any data‑analysis software.

Is the meter calibrated out of the box?

All units are factory‑calibrated against a certified reference light source. For critical applications, users can perform a quick verification using a known light standard to confirm accuracy.
