- Instant alert: Automatically sends email notifications when temperature/humidity exceeds thresholds or when the device loses connection, helping to address risks promptly.
2. Durability and Reliability "Japanese Standard"
T&D equipment is renowned for its durability in harsh industrial environments:
- Extremely durable battery: Models like the TR-5i have battery life up to 4 years.
- Optimal design: Waterproof (IP67), impact resistant, and operates reliably in deep-freeze storage (down to -60°C or lower depending on the sensor).
3. Flexible connectivity (Hybrid Connectivity)
T&D allows data retrieval across most modern protocols on a single device:
- Simultaneous support Bluetooth (connect phone) Wi-Fi/LAN (pushing data to the Cloud) and USB (Connect your computer). This ensures you always have a backup plan to retrieve your data even if you lose your internet connection.
4. Compliance with stringent standards.
T&D equipment is designed to pass the following tests:
- High precision: Extremely low error rate, comes with a Japanese calibration certificate, or can be easily calibrated at centers in Vietnam (such as Quatest 3).
- Data security: The software supports exporting files in non-editable formats, meeting standards. FDA 21 CFR Part 11 (for the pharmaceutical industry) and HACCP (for food).
5. Unlimited scalability
You can start with a single device and expand to a system of hundreds of measurement points in the factory without changing the management platform. RTR500B It has the capability of long-range wireless transmission (up to 150-500m), saving on the cost of cumbersome electrical wiring.
