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 & Benefits
Real-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.
