VBR-100 Quantum PAR Meter Separate Red Blue PPFD by De-Power

Description

Product Overview

The VBR-100 Quantum PAR Meter is engineered for precise measurement of photosynthetically active radiation (PAR) across the full light spectrum. Its compact housing measures 2.87 x 2.87 x 0.81 inches and weighs just 2.74 ounces, making it easy to handle while maintaining professional‑grade accuracy. The device captures total photosynthetic photon flux density (PPFD) and uniquely separates the contributions of red and blue wavelengths, giving growers insight into the spectral balance that drives both vegetative growth and flowering.

Equipped with a dual‑AAA battery pack that provides long‑lasting power, the meter operates independently of external power sources, allowing field measurements in greenhouses, vertical farms, and research facilities. Data is logged internally and can be exported through a Bluetooth connection to a dedicated mobile application, where users can visualize PPFD distribution maps, calculate daily light integral (DLI), and assess uniformity across planting grids. The sensor’s firmware has been updated to recognize the VBR-100 Plus naming convention, ensuring compatibility with the latest app features.

Construction focuses on durability and reliability. The sensor head is sealed against dust and moisture, meeting the demands of humid greenhouse environments. Calibration is factory‑set to ISO standards, and the device includes a self‑diagnostic routine that alerts users to any sensor drift or battery depletion. The user interface displays values in real time, with clear icons for total PPFD, red PPFD, and blue PPFD, reducing the learning curve for both novice and experienced horticulturists.

Usage

In commercial greenhouse operations, the VBR-100 is typically used to verify lighting uniformity across rows of crops. Technicians can place the meter at multiple points within a lighting grid, record the PPFD values, and generate a heat map that highlights hotspots or low‑light zones. This data informs adjustments to fixture placement, reflector angles, or supplemental lighting strategies, ultimately improving crop yield and energy efficiency.

For indoor growers and hobbyists, the meter offers a portable solution to assess the performance of LED grow lights, fluorescent tubes, or high‑intensity discharge (HID) lamps. By separating red and blue components, users can fine‑tune spectral ratios to match the specific growth stage of their plants, whether they are in vegetative or flowering phases. The Bluetooth‑enabled app provides step‑by‑step guidance for setting target PPFD levels and tracking changes over time.

Researchers in academic or corporate labs can integrate the VBR-100 into experimental protocols that require precise light dosing. The device’s ability to log data at defined intervals enables longitudinal studies of plant responses to varying light regimes. Its small footprint allows placement on moving platforms such as drones or robotic carts, expanding measurement capabilities to otherwise inaccessible canopy regions.

Why Choose Us

De-Power’s commitment to quality is reflected in the VBR-100’s rigorous testing and certification process. The meter ranks #3 in the Lab Photometers & Light Meters category on major e‑commerce platforms, with a 4.5‑star rating from over 300 verified purchasers. This reputation is built on consistent performance, reliable data capture, and responsive customer support that assists users with calibration, firmware updates, and troubleshooting.

Unlike many entry‑level PAR meters that provide only a single aggregate value, the VBR-100 delivers separate red and blue PPFD readings, empowering growers to make informed decisions about spectral composition. The device’s data‑logging capability eliminates the need for manual note‑taking, reducing human error and streamlining workflow. Additionally, the Bluetooth app offers cloud backup, ensuring that measurement histories are preserved for future reference.

Our after‑sales service includes a one‑year limited warranty covering manufacturing defects, as well as access to an online knowledge base and direct email support. Should a replacement be required, we provide expedited shipping to minimize downtime for commercial operations. This comprehensive support framework distinguishes De-Power as a trusted partner for precision horticulture.

FAQ

How does the VBR-100 separate red and blue light measurements?

The sensor contains dual photodiodes filtered to isolate the red (around 660 nm) and blue (around 450 nm) portions of the spectrum. The device processes the signals independently, presenting each value alongside the total PPFD, so users can see how much of the light is being absorbed by chlorophyll‑specific pigments.

Can the meter be used with any type of grow light?

Yes. The VBR-100 is calibrated to respond to the full range of photosynthetically active radiation, making it compatible with LED panels, high‑pressure sodium lamps, metal‑halide fixtures, and traditional fluorescent tubes. Its spectral separation feature is especially useful for LEDs that emit distinct red and blue peaks.

What is the procedure for calculating DLI with the VBR-100?

First, record the average PPFD over a representative period using the app’s logging function. Multiply the average PPFD (µmol m⁻² s⁻¹) by the number of seconds the light is on each day, then divide by 1,000,000 to convert to mol m⁻² day⁻¹. The app can perform this calculation automatically once the lighting schedule is entered.

Is the device waterproof for use in humid environments?

The sensor head is sealed to IP‑X4 standards, protecting it from splashing water and high humidity typical of greenhouse settings. However, it is not designed for submersion, so users should avoid immersing the meter in liquids.

How does the warranty and support process work?

De-Power provides a one‑year limited warranty covering any manufacturing defects. If an issue arises, customers can contact support via email or the online portal; a service request will be issued, and a replacement unit will be shipped at no additional cost after verification of the defect.
