So, you are looking at an environmental test chamber. Rather than buy a new one, you know very well that a used one will do just fine. Besides, you do not want to miss out on a money-saving opportunity, do you?
On the flip side, you’re not sure if buying a used environmental test chamber is, indeed, a money-saver. What if a used chamber’s performance isn’t as good? What if it needs more money – for maintenance and repairs?
#1: The Manner of Use
Find out exactly how an environmental test chamber was used. Simulation tests such as HALT (or Highly Accelerated Life Testing) and HASS (or Highly Accelerated Stress Screening) are a bit aggressive. If you compare them to stimulation tests such as temperature cycling and burn-in, simulation tests expose a chamber to a more strenuous activity.
Alongside, find out if an environmental test chamber was taken care of properly. This gives you information about its dependability, as well as its need for maintenance. Look at records such as service and maintenance records.
#2: The Type of Refrigerant It Uses
Do you know the type of refrigerant that a chamber uses? You should! Particularly, you may want to know due to the cost of future maintenance and repairs. There will come a time when you need to have an expert check a chamber’s condition, so you have to be ready.
Are you thinking of buying a used chamber with an old refrigerant system? An old refrigerant system could use a cooling field retrofit when it breaks down. Because of this, you may want to re-think. You may want to re-think because an old chamber – one that was built before 1995 – can cost a lot of money to fix.
On the other hand, you’re looking at a chamber for a real bargain if its refrigerant is made past 1995. This means that the particular used environmental chamber’s refrigerant comes with a cooling system that you can fix easily. You can fix it at a more affordable price, too!
