Keystone Industrial Trading Corporation was established in 1966.  It is a small family business capitalized at five million pesos. It has 10 employees.  Its office and warehouse is located in Pasay City. 

The company maintains stocks of analog measuring instruments from the U.S.A based H.O. TRERICE CO., and Canadian based WINTERS Instruments.  

In 1983, we began marketing TESTO hand-held digital measuring instruments. Additional services include repair and certification.

Our market is focused towards food processing, pharmaceutical, industrial, and air conditioning.  

Clients range from individuals, contractors, and small companies to large multinationals. We maintain dealers on specific products in selected markets.  

Occasionally we set up exhibits at trade fairs showcasing the latest offerings of distributed products. At times, seminars are held to introduce new products lines.

We offer the customer the appropriate solution to their measurement, data-logging requirement, and the necessary auxiliary infrastructure to carry them out.

Additionally, we offer instruments that are required to meet with government regulatory emission standard in industrial flue gas monitoring and indoor air quality standard, for a better workplace environment. 

Years of serving the customer with a high degree of customer satisfaction had helped grow our customer base. We intend to improve further as partners in quality measurement.
