Easy Installation, Quick Alarm: The Taimster Tire Pressure Monitoring System MS1 offers multiple alarm modes, including rapid air leak detection, high/low pressure alerts, high temperature warnings, and sensor battery low alerts. Sensors are pre-programmed with the monitor after production, allowing users to simply set their desired safe pressure and temperature values. Alarm safety ranges are -25% PSI to +25% PSI relative to reference pressure and -25°F to +25°F relative to reference temperature. Alarms activate when monitored data exceeds these safe thresholds. Solar and USB Charging: The system supports both solar and USB charging. Equipped with high-quality solar lithium battery panels, the monitor delivers efficient automatic charging and energy storage, extending operational life and ensuring reliable performance. Includes a USB charging cable for continuous power supply. If the display indicates low power despite sufficient sunlight, connect the USB cable to charge. Multiple Alarm Modes and Automatic Calibration: This TPMS provides comprehensive safety alerts, including high/low pressure and high temperature alarms. Upon sensor installation, the monitor automatically sets the current tire pressure as the baseline reference, eliminating the need for manual alarm value input, offering smart and convenient operation.
