SPECTRAL PAR METER

PG200N

PPFD, PFD, Plant Factory,Quantum PAR meter

UPRtek PG200N Handheld plant growth lighting detector

PG200N is a Handheld Spectra PAR Meter that conforms with the requirements of JIS AA and DIN B illuminance class.The main purpose of creating PG200 is to push the limits ofthe traditional quantum meter / plant detectors which only offer PPFD ( Photosynthesis Photon Flux Density), PFD(Photon Flux Density), Lux and basic lighting parameters. This time, PG200N PAR Meter is embedded with a G-sensor to help users adjust the measuring position dynamically. The sensor head is upgraded to the waterproof and dustproof level-IP66 to ensure that the precision of data is not affected by humidity. In addition, through the built-in PAR reference spectrum, users can instantly confirm the absorption of light by plants and provide proper light source. PG200N is the most intelligent and innovative meter to be utilized in LED plant factory equipment vendors, integrators, plant lighting designers and R&D institution.

Exclusive Spectrum PAR Meter with Axial Displacement Function, G Sensor

Users understand the angle of the PG200N by using G-sensor and adjust it to get the most appropriate horizontal position. It is recommended for indoor and outdoor plant measurement.
Application 1: Plant Factory site inspection. It is similar to horizontal “position sensor”function.
Application 2: Sensor head can be used with a selfie stick and camera tripod. Users can easily measure far reaching ranges and adjust the measurement point horizontally.

By using motion sensor (G-sensor), users can intuitively check the axial shift and the anchor point can be fixed anytime to avoid the artificial measurement error from happening

The First Handheld Spectral PAR Meter with Durable and Waterproof Sensor Head

PG200N sensor head is IP66 level with waterproof and dustproof functions which are suitable for field and humid environment measurements. It has a build-in logging mode which allow users to monitor, collect and record data for a long time. Moreover, PG200N can be connected with uSpectrum PC software for advanced analysis that enables the creation of an exclusive plant light formula database to make plant production more stable and more efficient. It is recommended for plant factories and greenhouses.

Plant Growth reference spectrum comparison

Plants utilize different photosynthetic pigments ( cholorophyll a, cholorophyll b, β-carotene and photosensitin) for the occurrence of photosynthesis in different wavelengths of light. PG200N Spectral PAR Meter is a professional plant light detector embeded with PAR reference spectrum for users to check whether the current plant growth light spectrum configuration meets the plant light absorption requirements. And if not, users can adjust their light source to meet the plants' basic light requirement instantly. It helps plants grow healthily. The following are the photosynthetic pigments:

(1) Cholorophyll a- Main absorption peaks are 418nm and 660nm. In photosynthesis, cholorophyll a mainly performs photoreation which is also called the main pigment. It widely exists in higher plants.
(2) Cholorophyll b- Main absorption peaks are 454nm and 643nm. It is an photosynthesis accessory pigments. It also widely exists in higher plants.
(3) β-carotene –Main absorption range is blue violet (400 nm -500 nm). It is the same as the chlorophyll b, which is a photosynthesis accessory pigment. It transmits the absorbed light energy to chlorophyll a for photosynthesis. It is widely available in green and yellow fruits and vegetables, such as carrots, mangoes, papayas, sweet potatoes, citrus and others..
(4) Phytochrome –It is a protein pigment in plants and is divided into 2 types which are active form-Pr (Phytochrome red with 673nm absorption peak) and inactive form-Pfr (Phytochrome far red with 732 nm absorption peark)。The phytochrome mainly absorbs red light and far red light through the light signal to regulate plant growth and development. 【1】

PG200N offers plant reference spectrum for users to compare and compensate the necessary light wavelength needed by plant.

Customizing PPFD (Photosynthetic Photon Flux Density) & PFD (Photon Flux Density) Range of Plant

Measurement wavelength can expand from 350 nm to 800 nm (UVA-FR). Users depend on their needs to identify the PFD wavelength.
