Supplier's note

  1. Technical Breakthroughs:

    • Certifications (FCC/CE): Enable global deployment without regulatory hurdles.
    • Extended Temp Range (-25°C to 60°C): Outperforms industry standards for extreme environments like Arctic warehouses.
    • BLE 5.0 Compatibility: Offers 2x faster data transfer than traditional Bluetooth, reducing lag in real-time alerts.

  2. Version Selection Guide:

    • Base Model: Ideal for small businesses needing basic monitoring (e.g., retail cold rooms).
    • Advanced Model: Best for labs or warehouses requiring longer battery life and IP67 durability.
    • Pro Model: Tailored for industrial or maritime use, with IP68 water resistance and ultra-precise readings for critical applications like pharmaceutical cold chains.

With the Pro Model’s IP68 rating, you can submerge it in water up to 1 meter for 30 minutes, ensuring reliability in flooded environments. Pair this with its ±0.2°C accuracy to maintain vaccine viability during transit.
