Hello everyone,
I use model CCS-400H/204. The closed-cycle refrigerator had the vacuum leak. The pressure in the sample space only decreased to 7x10^(-3) torr after I turned on the turbo pump in vacuuming the sample space. My oil pump and turbo pump were ok. I cleaned the rubber o-ring, 4 small window on the vacuum shroud, dust on the mouth of the flexible metal hose but the vacuum leak existed. Can you give me some tips to solve the vacuum leak of CCS-400H/204?
Yours sincerely,
Viet
