Are you interested in buying an environmental chamber? Well, know that it does not come cheap. This is why you may want to think about some factors to see if a chamber is in good working condition.
An environmental test chamber should control environmental conditions, right? Well, to do that, it should work well with an electric heater. The electric heater should let it create humidity and temperature conditions.
Check the electric heater of the refurbished environmental chambers for sale. Especially if you are going to buy a used or refurbished chamber, you need to check their heaters closely. Make sure their heaters are of excellent quality.
The Role of Testing Types
When checking out environmental test chambers for sale, think about the types of environmental test that you will do with these chambers. There are two common testing types. One is thermal testing. The other is thermal shock testing.
You should factor in testing types because these will help you choose which chamber is best for you. Should you go for a standard chamber? Or, should you go with a heavy-duty chamber?
Slow vs. Fast Testing
As mentioned, a type of temperature testing is thermal cycling. Thermal cycling is a process where you let a product reach extreme temperatures over time. Particularly, you let a product reach two extreme temperatures.
Thermal cycling is a slow process. To reach the desired ramp rates, you would have to wait long soak periods. Rather than speed things up, you simply have to wait during the soaking period.
Thermal shock testing is an alternative – and a faster testing type. If you compare it to thermal cycling tests, it achieves results faster. This is because it has at least two zones.
You will see that Zone #1 is dedicated to lower temperatures – and it features a lower temperature limit. Zone #2 is dedicated to higher temperatures. Like Zone #1, Zone #2 also features a limit – in this case, a higher temperature limit.
