Solar Monitor
TC-M423 / TC-MZ423- Dash-top display, 84 × 66 × 23 mm, 82 g
- Solar panel with USB charging socket
- Supplied with USB cable and anti-slip pad
A wireless, solar-charged tyre pressure monitoring system for cars, SUVs and 4x4s. Four sensors, one dash-top monitor, and an alert the moment a tyre drifts out of range, with nothing to wire in and nothing to subscribe to.
Sensors are available valve-mounted or internal, and the spare wheel can be added as a fifth position. Built to GB26149-2017.
It charges itself, it sets its own alarm thresholds from your tyres, and it tells you which wheel needs attention.
Charge it fully over USB before first use, then daylight keeps it running on the dash.
The pressure at pairing becomes the reference. It warns at 25% above and 15% below, with no thresholds to work out.
High and low pressure, high temperature, fast leak, low sensor battery and lost sensor.
Switch units from the keypad. No app, no account, no data cost.
One monitor, four sensors and the tools to fit them.
Inflate every tyre to its correct pressure first. Whatever it reads at pairing becomes the reference the alerts are measured against.
