I am trying to figure out what is the precision of these modules.
I need to build a precise temperature control system in which to control the temperature of 4 vessels filled with water.
Output is heaters.
I have been reading the CJ1W-TC modules specifications here
http://www.ia.omron.com/data_pdf/data_sheet/cj1w-tc_dsheet_csm1622.pdf
and would like to use either the CJ1W-TC101 or CJ1W-TC102
they are 4 loops modules which accept input RTD PT100 sensors.
In the datasheet on page 4 it says:
What does it mean?
I know the most basic immersion circulator (e.g. Polyscience) offers a temperature stability of ±0.07˚C, so I worry the Omron module could not even get close to that as best case scenario would be ±0.8ºC
But I am not sure what Indication accuracy actually means, I mean what indicator... it doesn't have a display!
Thank you

Indication accuracy:
Celsius: ±0.3% of PV or ±0.8ºC (whichever is larger) ±1 digit max.
Fahrenheit: ±0.3% of PV or ±1.6ºF (whichever is larger) ±1 digit max.
