hi guys,

if a system is suspect of containing moisture, how can i test it? i beleive its via an oil test from compressor, but will this be acurate as it will come in contact with atmosphere for a short amount of time?

if i test for acidity is this sufficient? or can i test for moisture? i know moisture makes the oil acidic but im not sure how much moisture is required? hope you understand :/

we have used a megger on the windings and found no break down of insulation (>1000mOHM)but sight glass is showing slightly wet, if you had dry/medium/wet its on the medium, personaly i dont trust the indiacator as i have had systems before under 2 torr for well over 16 hours and the indiacator still didnt got completly dry???? no rise on rise test either


thanks guys, have a good weekend!!!!
