Introducing the new Qualmark combined environment test system with ESPEC cascade refrigeration that eliminates the need for liquid nitrogen (LN2), making basic HALT testing possible for customers and locations where traditional HALT systems just aren’t feasible. Whether LN2 is too difficult or costly to attain and maintain, or just not possible, this is your answer. Likewise, this new system serves customers who want to save on LN2 by just using it as a boost during rapid thermal ramps, but can let the refrigeration take over for soak steps.

The Qualmark random shock/vibration table completes the system to create a combined environment needed for full HALT testing. This robust system brings together the proven, quality technologies from ESPEC and Qualmark product lines and meets your testing needs where you’re at, all while crushing your reliability testing needs in much less time, getting you to market faster.
