Overview
The Elreha Minimep 2434 A is a wall-mounted paperless datalogger engineered for long-term monitoring of temperature and humidity in industrial, pharmaceutical, and food storage environments. This system continuously records sensor data, displays real-time values on a backlit LC dot matrix display, and maintains compliance with critical regulatory standards including 21 CFR process control and HACCP Quality Assurance Systems.
Key Features
- Wall-mounted enclosure with backlit LC dot matrix display for clear visibility
- Real-time clock with 10-year typical battery backup maintains operation during power loss
- Supports four display languages: German, English, French, Dutch
- Alarm monitoring for high/low temperature and humidity with configurable time delay
- Networkable via RS-232 and RS-485 interfaces for remote data access
- Unlimited data storage even without mains power supply
- Error message memory retains last 6 recorded errors
- Three digital inputs for door contacts or external messages (potential-free)
- Easy operation with 3-key control interface
