Headquartered in Wheat Ridge, Colorado USA, Olson Instruments, Inc. is an industry leader in the manufacturing of Nondestructive Testing and Evaluation (NDT&E) Instrumentation widely used in the construction field. We design and engineer NDT systems that are first used by our sister company, Olson Engineering, Inc. (www.OlsonEngineering.com) before selling field-proven instruments worldwide that provide the quality, ruggedness and performance demanded by industry standards. The systems are assembled in-house so you can be assured that we have the bench strength to provide assistance for years to come. If you call in for Tech Support, more often than not you will be speaking with an engineer who has actually designed and used the equipment and/or written the software!

With Olson’s broad knowledge and experience, we provide personalized service for all of your NDT instrumentation needs. We do not outsource any tech support questions, and should you require software and/or hardware support, we welcome your questions and comments. If you don't find a product on our website that suites your needs, let us know. Purchase the instruments to do-it-yourself, or hire one of expert consulting engineers to find, characterize and assess the condition of structures—nondestructively.

Since 1993, Olson has been an established manufacturer of sensors and data collection systems. Our products are designed to address the requirements of the civil engineering industry for condition assessment. This focus has resulted in professional Nondestructive Testing & Evaluation, Geophysical and Laboratory test systems that are recognized world-wide for their durability, versatility, and superior quality.

In addition to optional add-on NDT test method systems for ultrasonic, sonic, seismic, vibration, structural health monitoring as well as custom systems, we develop and manufacture five main product platforms:

The Freedom DATA PC, the ultimate in a professional, field ruggedized NDT and Seismic Geophysical Testing Platform with over a dozen optional add-on test method capabilities

The NDE 360, a versatile, robust, ruggedized handheld NDT Platform. Includes up to a dozen optional add-on NDT and simple Seismic Geophysical test/software system options in one platform, making it a complete suite for nondestructive evaluation of civil structures at a very affordable price.

The "CTG’s—Impact Echo based Concrete Thickness/Flaw Gauges"

Verify concrete thickness and even detect internal flaws in one easy step without the need to drill, core or excavate. Requires no special knowledge or training to obtain thickness measurements.

The Freedom DAS PC for structural health monitoring, general purpose testing and data acquisition on up to 32 channels with easily switchable, flexible support of strain, potentiometer, accelerometer, thermocouple and other sensors for performance monitoring and load testing.

The Resonance Tester (RT-1) for determination of elastic moduli of concrete specimens and rock cores. A lab instrument with just 3 simple components that provides accurate results in less than a minute — simple to use, simple to learn!
