Thanks for all the input. I'm either going to go with the Auber unit "
Universal 1/32 DIN PID Temperature Controller for $36.95"
or a unit I found on eBay
eBay DIGITAL PID TEMPERATURE CONTROLLER for $19.35. This eBay unit is selectable for Celsius and Fahrenheit and works with RTD probes/Sensors in the PT100 style.

Key Features
100% Brand New Item ! Top Quality & High Performance
This 1/32 DIN Intelligent and Auto-tune Digital Temperature Controller is designed in accordance with IEC1010-1 and is ideal for various household, institutional & industrial heating and cooling applications, such as brewery, espresso machine, coffee maker, kiln, furnace, oven, refrigerator, motor and solenoid valve control application...etc
Ideal for temperature display, monitor or controller
Auto-tuning function is specially designed for non-experienced novice users.
The PID control with artificial intelligent enhancement for precision temperature control
The output can be set for SSR output control or relay contactor control by the user.
Five types of control output methods
The built-in relay can be configured as PID or alarm output. It can also drive a small heater/device directly if the heater/device draws <3 Amperes.
Fully compatible with Thermocouples of types T, R,J,B,S,K,E,WRe3-WRe25 and Resistance-Type Temperature Detectors of Cu50 & Pt100
Two LED indicators for relay and control output indications
Compact design, easy to install and operate
A Type-K Thermocouple (2 meters wire and measuring up to 800°C) will be included.
NOTE: An external Solid State Relay (not included, available for purchase in our store) has to be added if the Temperature Controller is used to handle device (3 Amps or over) via SSR output.
The item has been tested in perfect condition and will be well packed for shipment to buyer.
This is the
RTD Sensor I'll be using
Last question, seeing I'm only monitoring temperature and not controlling an element or anything I won't require an SSR or heat sink will I?
Not sure if I'll need an SSR but the relay is supposed to control the rapid on/off while the heat sink cools the relay maintaining a controlled temperature. Right?
Thanks
