Looking to use K type thermo couples to monitor pot, mid column , top column, looking for a digital display 3 read outs 0-200'C range.
K type sensors having very low thermal inertia allows quick readings & take control of heater.
Keen to get ideas out there
cheers :)

No shortage of people out there using them for exactly what you are proposing.

I'm using a Control 6410 NIST traceable precision digital thermometer:

FEATURES:
Displays minimum/maximum temperatures for last 24 hours (for each hour) and last 7-days (for each day); or last 31 days (for each day)
Range –100.00 to 199.99°C, resolution 0.01°, accuracy ±0.1°C; fulfills precise requirements for refrigerators/freezers
Ideal for ultra-low freezer applications
Alarm is settable in 0.1° increments and signals when temperature rises above/falls below set points
Permits easy one-key calibration by user
Traceable®: To assure accuracy an individually serial-numbered Traceable® Certificate is provided from our ISO/IEC 17025:2005 (1750.01) calibration laboratory accredited by A2LA. It indicates traceability to standards provided by NIST (National Institute of Standards and Technology).

SPECIFICATIONS:
Range: –100.00 to 199.99°C (-148 to 199.99°F)
Resolution: 0.01°
Accuracy: ±0.1°C
Functions: MIN/MAX MEMORY 24-hr (each hour), 7-day (each day), 30-day (each day), MIN/MAX with date/time display, HIGH/LOW alarm, °C/°F
Platinum RTD stainless-steel Probe: 0.13" dia; stem: 9", overall : 12"
Display: easy-to-read, 3-line. and 2 alarm LEDs
Cable: waterproof, 120”
Size: 2-3/4 x 4-1/4 x 3/4”
Weight: 5 ounces
Case: high-impact, chemical-resistant ABS plastic
Supplied: batteries, platinum RTD stainless-steel probe, cable, magnetic strips, Velcro® tape, bench stand, Traceable® Certificate

Very nice setup, however bit more than I really need, now my option use 2 digital multimeters with K sensor input & cheap K sensor display from china $7USD
would be nice to have 3 displays built in my heater control box :)

Plenty of inputs in this one :handgestures-thumbupleft:

Of course you would need to change the probes.
