# How to identify temp setting on a CH-152-35 thermostat

Pictured is a CH-152-35 thermostat. It is similar but not identical to the one described at http://www.wako-clinac.co.jp/product_en/ch-152-35_en/index.html

I don't have a way to heat this thermostat in a controlled fashion until the switch opens- So I cannot determine its temperature setting by experimentation.

There is more information than just the part number printed on the side of it. I am thinking that perhaps the "195" on the second row of text is the temperature rating - but I cannot find anything via Google that takes my idea from a guess to a fact.

Can someone please tell me if that "195" number is indeed the temperature setting for the thermostat and if the "4131" at bottom is useful information?

As a further help, maybe explain if this is standard marking technique for this type of component and where a reference for these markings might live?

• I don't have a way to heat this thermostat in a controlled fashion ... do you have access to a kitchen with an oven? – jsotola Feb 27 '18 at 22:48
• LOL, yes. Yes, I do. And if I put electronics inside of it with leads coming out to a meter or a lamp, I will pay very very dearly for doing so. Not everything is available for experimental use... – 111936 Feb 27 '18 at 22:50
• Just say that you're calibrating the oven so that it behaves better ... Practice an air of confidence while doing so ... – brhans Feb 27 '18 at 23:11
• Come for an electronics answer... get relationship management advice! LOL! Any input regarding the markings in the object? – 111936 Feb 27 '18 at 23:48
