Hoestar Inspection International Pte Ltd was established in 1992 and incorporated in 1999 providing general engineering services before diverting into inspection related services from 1993 onwards.

In the early days, the only inspection services that we provide was Infrared Thermography. Business was tough at that time because awareness of such technology was little known.

When the awareness of Infrared Thermography began to rise in 1997, we faced prices pressures from the new entrants in the market. Fortunately, as we had started in this business early, we had developed  very good rapport with our customers and had provided quality inspections at competitive prices so much so that our client base had begun to expand. At the present time we have more than 500 customers who are using our services in Singapore, China and Malaysia.

With our goal of providing a one stop condition inspection service to our clients, we had started to develop new capabilities in Motor Current Analysis, Partial Discharge Testing, Power Quality Monitoring and recently, in PD Fibre Online Monitoring Technology for on-line continuous monitoring. With our emphasis on service reliability and quality, we hope to become one of the top condition inspection company in the Asian region in the next 5 years. All these could not have been achieved without the support of our partners and staff who have over 20 years of inspection experience.
