Competitive advantages to mapping service provider
Since 1988, Performance Validation (PV) has provided validation, commissioning, and quality services to pharmaceutical, biotechnology and medical device manufacturing and distribution. For over 30 years, the company has operated under its mission to provide peace of mind for their clients in life science industries.
If you take into account the life of the sensors, the lifetime system cost is excellent. Certainly, there are the costs of the loggers and annual calibrations, which requires a sizeable up-front investment. But, those costs stretched out over the life of the system are more than reasonable compared to almost any other system we have looked at.
