DescriptionThe TES-1339R Data Logger Light Meter Pro is a digital illuminance meter designed for professional use. It can measure and log illuminance in both Lux and Footcandle (fc) units, and its data logging features allow for long-term monitoring and analysis of light levels. |
Key FeaturesMeasurements: Measures illuminance in Lux and Footcandle (fc). Measuring range: 0.01 to 999,900 Lux (0.001 to 92,927 fc), with a 5-step auto-ranging function. Data logging capacity: Stores up to 40,000 sets of data. Memory capacity: Stores up to 99 sets of data for direct reading on the LCD display. Spectral sensitivity: Features a spectral sensitivity filter that closely matches the CIE photopic curve, which is the human eye's response to light. Photosensor: Utilizes a long-life silicon photodiode and a spectral response filter for accurate and stable readings. Display: Dual, 4-digit LCD readout. Interface: Features an RS232 interface for connecting to a computer via the included cable and software for data analysis. Durability and construction: Compact, tough, and designed for easy handling. |
