One Instrument LTD was founded and started in 2001 with the idea of aggregating engineering, surveying, drafting, and construction tools and supplies into one combined catalog.

The Internet has helped the company grow into a tool and supply destination for many Professionals. Internet technology allows a company like On Survyeing Pte Ltd to keep its' catalog updated, but that alone is not enough. We remain highly competitive with our competition based on one sole premise, intense and personal customer service. With a slow-growth strategy combined with our high level of customer service, it's proving to be successful. While we cut prices, we do not cut customer service.

With the knowledge and use of the products we represent, along with the desire and ability to reach higher than expectations as a supplier, it is our goal to continue building On Survyeing Pte Ltd to maintain its status as a company that puts its customers first and foremost. We plan to have a continual process of building and refining the people and process that defines One Instrument LTD as a company.
