We like to have descriptive names or sentences for new things - and when the sentences become too long we turn to abbreviations - but then the descriptiveness disappear again 
Never the less I have found this little smart guy to be very dirt repellent. Only need some brief alcohol swab’ing. Done this twice now after a total of 120kg greens. What a huge improvement in maintenance.
Good to know that it is remaining that clean after 264lbs of roasted product. Nice! 
If I had a dollar for every time I’ve transposed characters in that acronym…
Lucky you! I’m still having to clean my new IR sensor every 10-11 kg.
Hey I like the acronym! XD
120kg a lot of coffee just for you?
Cleaning opening screws i.e. the door?
Same thing here. At first I didn’t assemble my IBTS properly. That was the reason why the probe temperature was higher at a certain moment than my IBTS. Af roasting about 20 kilograms, the issue came back. Had a look at my IBTS, but it was still at the right place. Conclusion: clean the IBTS every 10-15 kg. With a clean IBTS there is in the beginning of the roast about 15-20 degrees Celcius difference between the probe and the IBTS.
