The TR24 Multifunctional Coulomb Meter is an intelligent battery management device that integrates voltage, current, and capacity monitoring. It provides a precise and real-time power management solution for various battery systems. With its IP68 waterproof and dustproof rating, wide battery compatibility, and flexible display modes, it is the ideal choice for applications in automobiles, RVs, solar systems, marine vessels, and industrial equipment.

Core Features & Advantages

1. All-in-One Real-Time Monitoring
   • Accurately displays battery pack voltage (0-500V DC), current, power, remaining capacity, available runtime, and charge/discharge status.
   • Utilizes a high-precision current sensor to ensure data accuracy, with an error rate as low as ±0.5%.
2. IP68 Waterproof & Dustproof
   • The robust ABS housing achieves an IP68 rating, providing exceptional protection against water immersion and dust ingress. This rugged design ensures reliable performance in harsh environments, suitable for outdoor, underwater, and high-dust scenarios.
3. Universal Battery Compatibility
   • Supports a wide range of battery types, including Lithium, LiFePO4, Lead-Acid, and NiMH batteries. It can be easily configured to adapt to different battery parameters.
4. Smart Low-Capacity Alarm
   • Users can customize the low-capacity alarm threshold. The device automatically triggers an audible and visual alarm when the battery level falls below the set value, preventing damage from over-discharging.
5. Flexible Display & Operation
   • Equipped with a high-definition LCD screen that supports automatic/manual backlight adjustment for optimal visibility in varying lighting conditions.
   • Can be used as a standalone serial port screen or connected directly to a BMS (Battery Management System) to display detailed parameters without the need for an additional sampler.
