Ensure safety and prevent tire blowouts by installing the TST TST-507-FT-4-C Flow Through Sensor Tire Pressure Monitoring System (TPMS). This system accurately monitors tire pressure and temperature simultaneously in real-time, while offering you the ability to custom program high and low PSI settings on up to 4 axles.

Sensor Features:
- Detect leaks and temperature variances quickly and reliably
- Installation wrenches offer protection from theft
- Powered by user-replaceable batteries (CR1632)
- Flow-through sensors easily allow you to add or remove air, and check tire pressure without removing the sensor
- Easy to remove during seasonal storage to conserve and extend battery life
- Replaceable seal for long-lasting durability
- Each sensor can get programmed individually, so you can monitor per axle
- Internal memory keeps your settings after battery changes, no need to reprogram
- Water-resistant
- Battery Life: Approx. 1 Year (Replaceable CR1632)
- Sensor Weight: 0.09 lbs
- Sensor Dimensions: 1.7" length x 1" width x 0.94" height
Color Monitor Features:
- Full-color display
- Can handle up to four trailers, and handle up to 115 tires.
- Large illuminated display shows PSI and temperature simultaneously
- Built-in rechargeable lithium-ion battery runs up to 36 hours wirelessly
- Operates on vehicle 12-volt DC or hardware
- Built-in antenna
- Displays Read-Out Warnings
  - LO PRESSURE, HI PRESSURE, HI-TEMP, FAST LEAK, etc.
- Buttons are on the front of the monitor; easily accessible and well labeled
- Automatically drops any towing or towed trailer/vehicle that is not in range
- You can park either the front or the back sensors
  - After you get to your destination you can drop the RV sensors off the display by hitting a few buttons
  - Now you can take the display to the towed vehicle to monitor the tires while driving around
- Can handle up to 218 PSI
- Customize high low pressure and temperature thresholds
- HI-TEMP alarm is adjustable to be as low as you want
- Automatic illumination adapts to any light level
- Auto scrolls - No need to push buttons
  - Every few seconds it will display a different tire's PSI and template on the screen
  - The tire being shown will be blinking on the display
- Flashing LED light and audible alarm indicate when pressure or temperature exceeds preset thresholds
- Alerts can be read across the monitor
- The range is upwards of 60 linear feet from the tire to monitor.
  - Even further range with included repeater
  - The repeater is used in instances when the distance between the receiver and sensors is greater than 34 ft.
- Read pressure in PSI, BAR, Kpa, Kgf/cm2, temperatures in F or C
- Easily installs with rubber dashboard mount or suction cup mount
- Monitor Weight: 0.30 lbs
- Monitor Dimensions: 4.6" length x 2.99" width x 1.06" depth.
