## Questions & Answers

**Q: Can you purchase a (433 MHz or 915 MHZ) TP60 Monitor separately?**
A: On both the Amazon website and ThermoPro website the TP60 series monitors are only sold paired with the transmitters.  So it appears that you cannot purchase the monitor separately.

**Q: What is battery life, these and the base uses reg aaa, worry i will go through alot when other manuf have button cell lasting for 1 yr?**
A: Mine last a long time

**Q: Which remote sensor do i need for a tp-67?  the original sensor was rechargeable.**
A: Searching for the "TP67" on the Amazon site brings me to the TP67B.  (So, I will assume that is the one you have.)  While I do not find in the text description any specifics about the remote sensor, expanding the view of the remote that is pictured with the base unit I see that it uses 915 MHz for the signal.  Searching for "thermopro remote sensor" brings me to where the remote TX-2 and the remote TX-2B are shown.  The TX-2B uses 915 MHz for the signal, so it will work with the TP67B base unit.  (The TX-2 uses a different frequency for the signal.) 
I did not realize this detail when I ordered extra sensors for a ThermoPro TP60S earlier this year.  Amazon accepted the return of the units that did not work for me, and I ordered ones with that correct frequency for the base.   I'm well pleased with the unit.
