Thanks for all the information again. Will be setting up some ice, boiling water and a higher temp from my Antex work station to check the calibration of the Comark 1602 electronic thermometer. My dad had put 8 GP rechargeable batteries in the back of the Comark 1905 so it will be interesting to take the back of the 1602.

Have found it so useful as a needle moving up or down is so much more informative than a digital thermometer changing figures quickly. Just placed the soldering iron bit on the end and rotate the iron for the maximum temp reading. Both meters have been well looked after with no cracks or scratches on the cases. Is there any calibration notes for this meter still floating around as I had also contacted Comark without any luck.
