what to use for dual temperature display

[barnartist]

I installed temp probes in my Eko to get a better understanding of what's going on. The hand held digital meter I use does not stay on continuously and is not back lit.
I want to constantly monitor my gas flame temp and my stack temp, so it needs to handle up to 2000f.
Please suggest an economic option. Will this work?

Looks better than what I have... you want NO/NC contacts (called form C contact). The one i have is only NO, If I had a NC, I would have connect a buzzer with a 9V battery to wake me up when there is a loss of power.

So in your estimation this device will simply display both my temperatures for me?
The alarm idea is a good one.

Nop, sorry, it will not read 2 values...
There is a PV value and a SV value. PV mean Process Value (temperature Value) and SV mean Setpoint Value (what you want the process to be)...
This controller will try to control the process for SV=PV.
So if you want only to read 2 value, you need 2x of these, or another product. ( you will probably end with 2x of these, they are cheap... )

2000F is a lot of heat... you will need to choose the temperature probe that connect to the controller carefuly....
