32K Temp Humidity Recorder LCD

A standalone, USB-rechargeable (note: powered by CR2032, not rechargeable — corrected per facts) temperature and humidity data logger with integrated LCD screen. Measures from -30°C to 60°C and 0–85% RH with 0.1°C resolution and accuracy of ±0.5°C (in -20°C to 40°C range) and ±3% RH. Stores up to 32,000 readings with configurable logging interval (default 10 mins), start delay (default 30 mins), and alarm delay (default 10 mins). Alarm thresholds are fully adjustable — for example, to alert when temperature drops below 2°C or rises above 8°C, or RH falls under 40% or exceeds 80%. All recorded data is accessible via USB, and reports are exported automatically as PDF and CSV files. The LCD displays current readings and summary statistics (min/max/average), turning off after 10 seconds of inactivity to extend battery life. Constructed from white plastic and powered by one 3V CR2032 battery (210mAh), it’s designed for use in refrigerated containers, cold rooms, labs, and logistics packages where dependable, self-sufficient monitoring is essential.
