It combines automatic calibration, solar charging, a color LCD with adaptive backlight, and precise pressure sensing to reduce tire wear and help you spot problems early. The system’s sensors install on valve stems and transmit data wirelessly to the dashboard monitor so you can see live readings while driving or parked.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the M13 detect and warn about unsafe tire pressure?\u003c\/h3\u003e\n\u003cp\u003eThe M13 uses built-in pressure chips in each external sensor to measure PSI from 0–87 with approximately ±1.5 PSI accuracy. Once you inflate tires to your chosen pressure, sensors record that value as the reference and will trigger alarms when pressure drops 15% below or rises 25% above that baseline, so you don’t need to program thresholds manually.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eAutomatic reference-pressure calibration when tires are set to target pressure\u003c\/li\u003e\n  \u003cli\u003eVisual and audible alarms for overpressure and underpressure\u003c\/li\u003e\n  \u003cli\u003eTemperature monitoring to help spot heat-related problems\u003c\/li\u003e\n  \u003cli\u003eSensor range suitable for most passenger vehicles and trailers under 38 ft\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat powers the sensors and how long do they last on the road?\u003c\/h3\u003e\n\u003cp\u003eEach sensor includes a small battery augmented by an integrated high-efficiency solar panel on the sensor body. The solar-assisted design reduces dependence on internal battery life by charging continuously in daylight while built-in protections prevent overheating or overcharging.

The monitor’s HD color LCD auto-adjusts brightness and features an anti-reflective screen so readings remain legible in bright sunlight or at night.

It suits anyone who prefers automatic calibration, solar-assisted sensor power, and a clear, adaptive display — especially owners of travel trailers up to 38 ft. If you routinely tow long trailers or need extended transmission range through metal frames, budget for a Masoll signal booster to guarantee continuous coverage.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Does the M13 require manual alarm thresholds?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: No. Sensors auto-calibrate to the reference pressure and alarm at 15% low or 25% high automatically.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Can I use the M13 on a trailer longer than 38 ft?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes, but Masoll recommends adding a signal booster for reliable connectivity on trailers over 38 ft.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"Masoll","offers":[{"title":"Default Title","offer_id":67585711014073,"sku":"B0D943S8NW","price":115.11,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0822\/3765\/3177\/files\/masoll-front-display.jpg?v=1790476475","url":"https:\/\/redleafauto.ca\/products\/masoll-m13-tire-pressure-monitoring-system-tpms-4-sensors-solar-assisted-color-lcd-for-rvs-trailers","provider":"Redleaf Auto","version":"1.0","type":"link"}
