VBR 200 PAR Meter for Grow,Data Logger,Test PPFD,DLI,LUX,CCT,Temperature,Humidity,VPD.Dimmer

Maintain Target PAR Automatically with Light Dimmer Control. Measure real-time PAR and automatically adjust grow light power to keep PAR at your target level. When sunlight increases, light power is reduced; when sunlight decreases, power increases. Keep PAR Constant in Greenhouse Conditions. Designed for environments with changing sunlight. Maintain stable PAR for plants throughout the day, avoiding overexposure or insufficient light caused by sunlight fluctuations. Optimize Plant Growth While Saving Energy. By dimming lights when natural sunlight is strong, the system reduces unnecessary power consumption while ensuring plants always receive consistent light levels. Accurate PAR, PPFD & DLI Measurement. Measure PAR (PPFD) based on McCree curve (400–700nm). Record DLI automatically to understand total daily light exposure for plants. All-in-One Environmental Meter. Also measures LUX, CCT, temperature, humidity, and VPD. View historical data via Windows system for deeper analysis.
