Calibrating Coolant Temp Sender with Temp Gauge
I need to calibrate the Coolant Temp Sender in my Duratec with an Omex 600 ECU.
I was trying to find a thermometer which goes from 0 to 120 and realised I already have one in my Smiths temp gauge and sender.
So my question is, is the temp gauge and sender likely to be accurate enough for the purposes of calibrating the sender for the ECU?

I took the sender out of my car
Room temperature around 16 degrees, noted the resistance, immersed in icy water 0 degrees, dropped in boiling water 100 degrees then added the same
amount of ice water to the boiling water, 50 degrees
If you need more readings then stick the above into excel, graph and trend curve.

I just did mine at 0 and 100C
That seemed to be ok

A good method. I used something similar (our fridge is a stable 4deg).
If you really want to get a slightly higher set point than 100deg, then a saturated solution of NaCl (table salt) boils at 110degC (quite a lot of
salt in a saturated solution so keep the volume smallish). Not worth the bother though.

I have a cheap multimeter that has a thermo couple and temp read out, probably going to use that when/if i need to calibrate mine.

In fridge 5 degrees, in steam 100 degrees, under arm pit body temp.
Duratec Engine is fitted, MS2 Extra V3 is assembled and tested, engine running, car now built. IVA passed 26/02/2016

Would a laser thermometer do it
They can be bought quite cheaply
Point it at the area where the sender sits to read the temp
Useful for other diagnostic stuff too

Thanks for the advice guys. I think Ill do the ice, room and boiling water temp and probably just sense check that with the gauge.
