FAQ

Sciemetric Technologies India Private Limited (TASI India) is the concerned company involved in installation, services and repair for all the Cincinnati Test Systems (CTS) test instruments and machines.

An acceptable leak rate refers to the maximum quantity of fluid that can escape from a product or system within a specified time frame, while still ensuring the product remains functional and safe. This threshold is determined by either the manufacturer's internal quality standards or by external regulatory requirements applicable to the specific industry.
