When using a wireless Bluetooth probe how far from away from the handset will the probe register a signal?

Typically the probe will transmit distances up to 10 m (line of sight).

Can you connect two wireless Bluetooth probes to a 440 handset?

Unfortunately no. The handset is designed to work with a single wireless Bluetooth probe, a single wired probe and an additional Type K mini plug style thermocouple can additionally be fitted as well.
