Year Founded:


In 1976, Chester McKee fulfilled a lifelong dream and founded In-Situ Inc. from the basement of his Laramie, WY, home. Now headquartered in a modern manufacturing facility in Fort Collins, CO, In-Situ has become an international company with more than 130 employees specializing in the design, manufacture, and worldwide sale and rental of scientific equipment for the environmental and water-monitoring markets.

Throughout the years, In-Situ Inc. has become known for innovation, quality and customer service. In 1984, the HERMIT (Hydrologic, Environmental, Remediation and Monitoring InstrumenT) was the first datalogger in the industry to combine field ruggedness with ease of use and high accuracy for pump tests and long-term monitoring. It led to the development of the HERMIT 2000 and 3000 dataloggers. In 1989, In-Situ introduced the world’s first in-well water-level data logger. The TROLL 4000, released in 1995, was the company’s first all-in-one datalogger/transducer/temperature sensor and became the industry standard for a complete, self-contained, long-term monitoring solution for groundwater. The name TROLL was chosen because like a HERMIT, it lives isolated in the environment for long periods.

During the early years, much of In-Situ's business entailed consulting for and selling monitoring equipment to the in-situ uranium mining industry.When the mining industry fell on hard times, In-Situ began selling its instruments to companies that were cleaning up hazardous waste sites. Early on, the company developed the practice of closely working with its customers. It is a practice that continues today and is key to In-Situ's ability to move into new markets and design products that efficiently solve real-world problems. Today In-Situ instruments monitor groundwater, surface water and coastal waters in applications that include aquaculture, mining, flood warning, stormwater monitoring and more. In-Situ will continue to  meet the ever-changing needs of our loyal and valued customers with innovative instrumentation and software solutions.
