Description Descriptions: Motor or ESC failure is often caused by heat Heat and electronics do not mix. Electronics are more efficient and reliable at lower temperatures. Running your motor and ESC as cool as possible is always a good idea. If you keep them cool, they should last longer and most likely increase your runtime. In all forms of powered remote control gearing, the operating temperature of the main driving motor or engine is an important factor to consider for longevity and performance. The correct operating temperature will depend on the load or conditions the motor/engine must drive. The operating temperature for gas, nitro engines has different characteristics and impacts on overall performance. Therefore, it 39;s essential to understand the specific requirements and optimal operating temperature for your particular motor or nitro engine to ensure that it operates at peak performance and lasts as long as possible. Above are maximum temperature values for different power forms that serve as informative sources. Features: Ready to Measure: With its built-in BT, the Thermologger Duo allows instant communication via a mobile app, saying bye to cables. Accurate Temperature Measurement: This Thermologger Duo provides accurate temperature measurement with a high degree of precision, ensuring that you get reliable readings every time. Wide Temperature Range: With a temperature range of -20~210 (-4~410), the thermocouple thermometer is suitable for a wide range of applications, including ESC, motor, servo, Lipo battery, etc. Long Battery Life: It is powered by a CR2450 coin cell battery, which is included with the device and lasts for approximately ninety-six hours of continuous work* under normal operation. Portable: The device is also lightweight and portable, making it easy to carry around.
