PJG4 pro Bluetooth Stroboscopic Illuminance Meter
¥3.57
The PJG4 pro Bluetooth Stroboscopic Illuminance Meter is a pocket-sized spectral analysis device with a wide detection range of 350–1070nm, delivering one-step calculation of optical power distribution, flicker parameters, and plant lighting metrics. It outputs 40+ professional photometric parameters including illuminance, correlated color temperature, color rendering index, flicker index, and blue light hazard irradiance. Built-in TM-30 color quality evaluation and CIE 2015 observer perspective analysis provide precise, reliable data for lighting quality assessment.
Weighing only 48 grams at 52×34×30mm, the device features a built-in lithium battery supporting over 100 minutes of continuous use. Bluetooth connectivity pairs seamlessly with a mobile app (Android & iOS compatible), eliminating cable limitations and enabling on-the-go measurements. Data exports to Excel or PDF reports with one click, and PC software integration plus secondary development support are available. Ideal for indoor lighting, commercial lighting, plant factories, luminaire quality inspection, and laboratory research.
