The SPARKlink interface is no longer available. The recommended replacement is the low cost AirLink interface which allows a single PASPORT sensor to be connected to your device either via USB or Bluetooth® Smart. Want to check compatibility?
Also available are the AirLink 2 and SPARKlink Air which offer both USB and Bluetooth® classic connectivity. The AirLink 2 has a single PASPORT port while the SPARKlink Air has 2 PASPORT ports and jacks for voltage and temperature sensors just like the SPARKlink.
