ML3 ThetaProbe Undergoes Highly Accelerated Life Testing (HALT)

Delta-T Devices’ product design and testing aims to establish the highest degree of performance and reliability we can achieve for each our instruments. Our rigorous testing regimes include extensive water resistance and thermal shock tests, and most recently with our ML3 ThetaProbe – Highly Accelerated Life Testing (HALT).

HALT is a way of effectively simulating rigorous usage over a long period of time – by subjecting an instrument to sustained high temperatures over a relatively short period of time. Not only does this form of testing assess longevity and sustained consistency of accuracy, it also demonstrates an instrument’s ability to function beyond its stated specifications.

Multiple ML3 ThetaProbes were HALT tested for 149 days at 90°C which is the equivalent of 10 years usage at 30°C*. After electrical testing, all of the ML3’s were still in calibration and functioning perfectly. Label discoloration was the only sign of degradation, as you can see in the picture below.

When Delta-T develop products for use in the field, we not only aim to meet the requirements of all relevant IP standards, but, where possible, to surpass them. All of Delta-T’s scientific instruments undergo comprehensive testing and benefit from attentive, on-going after-sales technical support.
