SD Card Real Time Data Logger

The Lutron MHT-381SD is a high-precision data logger designed for recording and monitoring environmental humidity and temperature in industrial and professional settings. ✅ Key Features & BenefitsReal-Time Data Logger with Time Stamp: Automatically logs Humidity & Temperature data in real time, storing each reading with complete timestamp (Year/Month/Date, Hour/Minute/Second) onto an SD memory card (1GB~16GB). No extra software required — data easily exported to Excel for quick analysis. Versatile Connectivity: Equipped with both RS232 and USB interfaces for flexible PC connection. Optional RS232 cable (UPCB-02) or USB cable (USB-01) available. Simultaneous Dual Display: Humidity and Temperature are shown simultaneously on a large, clear LCD — ideal for professional monitoring. High Precision Measurement: Humidity: 0.1% RH resolution Temperature: 0.1°C resolution Utilizes a high-accuracy capacitance-type humidity sensor for reliable readings. Configurable Sampling Rate: Adjustable from 5 to 600 seconds or Auto Mode, which saves data only when values change significantly — optimizing storage. Power Options & Longevity: Operates on 6x AAA batteries (1.5V) or optional 9V AC adapter. Low power consumption design ensures battery life exceeds 1 month (with 60-second sampling). Microprocessor Controlled: Ensures high reliability, stability, and low power consumption. Data Ready for Analysis: Compatible with optional data analysis software (SW-U801-WIN) for advanced graphing and processing. Patented Design: Certified patents across China, Taiwan, Germany, and Japan — global innovation recognition.
