Is ALD/SoHaR MTBF Calculator free?
MTBF Calculator is a freeware. It is absolutely free - there is no time limit or installations count limit. There is no Ads. There is no commercial version of this product. There is no subscription to newsletters. Just install and use it.

Why is it free?
ALD .has been working in the field of reliability, safety and quality of the safety-critical and mission-critical equipment (mainly aerospace, defence, transportation and telecommunications) for more than 25 years.
We support the promotion of System Reliability and Safety and wish to make Reliability Prediction more accessible for reliability engineering practitioners and students.

Interested in a quick quote and time estimate for the  MTBF performed by our reliability engineering team?
We recognize that often organizations that do not perform reliability engineering tasks routinely may find it difficult to justify the cost of dedicating an otherwise busy engineer to learning a software tool (free or not) and taking the time to perform a task that he or she are not familiar with. Often in these cases it is cost effective for your organization to outsource these tasks to a team that specializes in this work and can provide the required results efficiently and at a low cost. SoHaR's reliability engineering team performs MTBF predictions daily and we would be glad to take on your tasks. Check out our quick, no strings attached, MTBF quote. It may be the solution you are looking for.

How to use the MTBF Calculator for reliability prediction?
ALD/SoHaR MTBF Calculator is Windows Desktop application. You should download and install it on your PC with MS Windows (XP, 2000, Vista).
For usage instructions, please see the MTBF Calculator User Manual - Reliability Prediction with ALD MTBF Calculator.
