Can I use a regular digital thermometer as a cylinder heat temp gauge? Answered
I want to make a cheap cylinder head temperature gauge for my 150cc scooter. I have owned one before which worked well but it was rather expensive. I'm more interested in being able to detect a temperature spike and avoid a blown motor than determining an acurate temperature. The last gauge I owned used a probe with a ring on the end that acted as a washer between the spark plug and the head.
If I buy one of these probes:
And a digital thermometer with a probe like this:
Could I just splice the wires together and be away laughing? I'd need to find out what the temp range of my engine is first.....my last 2-stroke 150cc ran at about 275F and melted at 400F, 4-strokes should run cooler right?
Any thoughts would be appreciated :)
