Masoll M13 TPMS with 4 Sensors, 0–87 PSI
Product description
This RV and trailer tire pressure monitor offers continuous protection for long trips by showing live pressure and temperature for four wheels, with features aimed at road users who tow or drive larger vehicles. The Masoll M13 TPMS combines solar charging, auto calibration and a clear LCD so you can keep an eye on tires during travel and camping.
Key Points
The system monitors pressure from 0 to 87 PSI with a manufacturer-stated accuracy of about 1.5 PSI, helping detect underinflation or overinflation early. Sensors auto-calibrate when you set the standard pressure, then trigger alarms if actual pressure rises roughly 25% above or falls 15% below the reference, according to the manufacturer. The display adapts brightness for day and night and includes anti-reflective treatment for readable information in bright conditions. Consider adding a Masoll signal booster if your trailer exceeds 38 feet, since longer trailers may weaken the wireless transmission.
Technical Specifications
- Name: Masoll M13 TPMS
- Pressure range: 0–87 PSI
- Pressure accuracy: 1.5 PSI (manufacturer claim)
- Sensors included: 4 external sensors
- Power: Solar charging with overheat and overcharge protection
- Display: Color LCD with auto backlight and anti-reflective screen
Benefits
Solar charging reduces the need to replace batteries frequently and the monitor uses an auto wake-up and sleep cycle to conserve sensor power. The auto-calibration removes manual threshold setup, which simplifies installation and day-to-day use. Clear numerical readouts for both pressure and temperature make it easier to spot anomalies before they lead to costly tire damage or reduced fuel efficiency. The wide pressure range supports passenger cars, SUVs, pickups and RVs or trailers under 38 feet.
Usage Recommendations
Mount the M13 monitor within the cab or on a dash area where the solar panel receives some light for continuous charging, but avoid placing it in direct, prolonged sunlight that could overheat any interior. When installing sensors, inflate each tire to the desired reference pressure first so the system can record the correct baseline reading. During long tows, check the monitor periodically for alarms and note that wireless signal strength may drop with additional trailer length, so test communication before setting off on extended trips.
