Comark

[Ashuraya]

Hi,

I bought this Comark 1624-4 thermometer without the probes (T type) for 10 Aussie dollars. it seems a precision lab grade thermometer, and it turns on and meter has smooth movement, even though there was battery corrosion which i dealt with.
I wonder if anyone can help me in finding service manual, schematics or calibration manual if available for this tool

your help is much appreciated
