1. Introdución
The Elitech RC-4HC is a multi-use digital temperature and humidity data logger designed for precise environmental monitoring. It features both an internal temperature-humidity sensor and an external temperature sensor, allowing for dual measurement capabilities. This device is ideal for applications requiring accurate temperature and humidity tracking, such as in medical refrigerators, vaccine storage, and general cold chain logistics. It can record up to 16,000 temperature points and 16,000 humidity points, providing comprehensive data for analysis.
The logger is equipped with audible and visual alarms to notify users of temperature or humidity excursions beyond set thresholds. Its powerful LCD provides all key recording information, including alarm status and temperature statistics in both Celsius and Fahrenheit. Data can be easily exported to PDF or Excel formats via a USB connection to a PC.
