Versatile Ht45 Smart Watch for Activity Tracking and UV Detection

The HT45 includes a small UV LED light that emits ultraviolet rays (typically 365nm or 395nm). When activated, it illuminates security threads or watermarks on banknotes that are only visible under UV light, helping to verify authenticity. Please note this is a basic tool and not a professional-grade verifier.

No. The HT45 has a 3ATM water resistance rating, which means it can handle rain, sweat, and hand washing. However, it is not waterproof enough for swimming, diving, or hot showers, as steam and pressure can damage the internal components.

You should download the 'FitCloudPro' app from the App Store or Play Store. This app manages your data synchronization, settings, and firmware updates. Ensure your phone's Bluetooth is enabled before pairing.

No, the HT45 typically uses a TFT LCD or IPS color touchscreen. While it offers good visibility and touch response, it does not have the high contrast and deep blacks of an AMOLED display. It is designed for clarity and durability at an accessible price point.

With typical usage (notifications, periodic heart rate checks, and moderate screen time), the battery lasts approximately 3-5 days. If you keep the screen always-on or use continuous monitoring features frequently, the battery life may reduce to 2-3 days.
