The heater controller is about $20.
The sendor $130.
A 40 LED display about $40. You can use a DVM but the LEDs are much closer to real time. With a meter it's hard to read changing numbers.

That's the heater controller. The operating temp of the sensor is 850d centigrade, so it needs warmed up in a special way, and then the O2 pump can be prodded into action.
