Selecting the Right L-N2 Coolant Delivery Hose

Expendable cryogenic liquids (L-N2 or L-CO2) deliver quick, accurate, economical and precise cooling for testing electronic systems and components.  Using the right hose will help make sure you get the best speed reliability and long term economy out of your coolant.

Thermal Testing Limit Safety

Inherent in their performance capabilities are some risks, primarily the possiblity of exposing items (and people) to extreme temperatures resulting in damage, injury or combustion. When testing it is obviously important to make sure devices or samples to be tested are not exposed to temperatures outside the intended temperature range.  In cases such as flight or space hardware the cost of disqualified hardware, even if it was only briefly exposed to excessive cooling alone can be enormous.

Thermal Testing with Conduction? – Double Check your true area of Contact!

To achieve the benefits of thermal testing with conduction, thermal platforms also known as Hot/Cold Plates are used to force devices to specific temperatures.  While Thermal Platforms may not work for every application, where they do, they offer a distinct advantage in speed, accessibility, efficiency and production throughput.  Items with irregular surfaces or even vials or beakers can often be fixtured to work well on a platform and allow for much better cost efficiency than found with temperature chambers.

Replacing programmable instruments, keeping software compatibility in an automated test

When an instrument eventually goes obsolete or for any other reason a new instrument is put in place of one that is already a part of an automated test system, some programming work will follow to make the transition complete.  Even if the instruments are supposed to be software compatible, there are often minor details to tend.  The good news is that it is usually not that difficult or involved. Of course exceptions can be noted but usually it is not as big of a project as some anticipate.

Thermal Testing Equipment: Maximizing Value

In the world of Test and Measurement, there are numerous options for your temperature testing equipment.  They can have a significant impact on costs, up front and ongoing as well as ease and quality of results.  For maximum value from your equipment, it is helpful to better understand the methods and choices available to you.

How Cooling With CO2 works

Liquid CO2 (L-CO2) is a popular refrigerant and is also known as Refrigerant R-744 according to ASHRAE (Formerly the American Society of Heating, Refrigerating and Air Conditioning Engineers).

Temperature Testing – Which Cooling Method is best?

Comparison of cooling methods for Environmental Testing of Electronics
Many electronic components and systems require thermal cycling in manufacturing or the laboratory for system test, burn-in or design validation.
While improvements in heat pump design allow compressors to heat as well, in most cases resistance heating is the heating method of choice, this is a discussion of cooling options. For cooling methods there are several choices.
