Place of manufacture: Mainland China

 

Physical

Sensor weight: 10g

Lock nut weight: 2.5g

Sensor dimensions: 21.6mm  max OD x 20mm height

Fitting: standard Schrader valve

Extension of valve when WiCap fitted: 13mm

(Please check that the WiCaps, when fitted,

will not extend beyond the outer wall of your tyres)

 

Wheel balance: may be impacted at high speeds by fitting sensors to tyre valves. Generally this is not an issue at legal towing speeds. If vibration is detected or you are in doubt, wheel balancing is recommended

 

Water and dust protection: IP67

(applicable only when WiCap is fitted to a tyre valve)

Kit contents

Presentation box with magnetic closure

WiCap sensors: 2 or 4

Lock nuts: 2 or 4

Folding spanner for easy lock nut and battery replacement

App:

TPMSii app for iOS and Android

Compatible with all mobile devices using Bluetooth 4.2 and 5

App uses mobile device's screen for display of pressure data

Pressure limit warnings: speech, vibration, visual

Speech selectable: on/off

Pressure measurement range up to 180psi (13 bar)

Speech and visual warning (for low inflation pressure) lower limit range: 1.5 to 36.2 psi (0.1 to 2.5 bar)*

 

* We recommend setting the lower limit speech and visual warning threshold at 20% to 25% lower than cold inflation pressure. Due to software limitation,this is not possible with

tyre cold inflation pressures of > 45psi to 48psi respectively.

You'll still get accurate pressure readings whatever your tyre pressures or settings.

 

Speech and visual warning upper limit range:

40.6 to 92.8 psi (2.8 to 6.4 bar)

Speech and visual warning for rapid air loss:

unlimited pressure range)

 

Speech warning, where applicable: American English

 

Tyre pressures are displayed for up to four tyres

 

Pressure units used for screen display :

selectable psi, bar, kPa

 

Number of sensors supported: 2 to 4

 

Battery level warning
