Hallöe, jetzt hab ich mein altes Thermometer zerdeppert. Allerdings hab ich ja da noch diese drei Jobo-Farbthermometer, ist also kein Problem, hab ich geda...

Hi there, I’ve just smashed my old thermometer. But I’ve still got those three Jobo colour thermometers, so I thought it wouldn’t be a problem. Except they’re showing 16.8° + 18.8° + 19.4° in the same beaker – oh, sorry... Big question: is there a quick-and-dirty solution to work out which of the three is the most accurate? – I realise it doesn’t really matter as long as I always use the same thermometer. But given the rather significant deviation between these ‘precision’ devices, I’d rather know for sure, just in case next time ‘luck and glass, how easily they break’. The scales range from 10° to 50°, so ice water won’t do the trick. Wishing you lovely light, Frank

Perhaps you could calibrate it using a clinical thermometer from the “first-aid kit”? I think those should be quite accurate between ~37°C and 40°C. Best regards Hermann

Hello, That sounds reasonable, thank you very much. I popped round to my neighbour’s straight away to borrow a clinical thermometer. The difference was alarming (2.5°), so now I’m not quite sure whether these electronic thermometers might not have some sort of built-in display discrepancy, designed to convert the oral temperature directly to core body temperature? Anyway, I’m in the process of getting myself a Greisinger for the workshop; that’ll be my standard from now on, no matter how inaccurate it is (though with a Greisinger, it should be pretty close to the mark). All the best, Frank

Greisinger is the only one worth using; I use it too – it’s accurate and quite quick. Regards Hendrik
