H2scan is the first and only company to receive FM Approval for a H₂ sensor with its GRIDSCAN 5000 product.

Utilized in transformer health monitoring, the GRIDSCAN 5000 H₂ sensor uses H2scan’s field-proven solid-state H₂ sensor adopted by most dissolved gas analysis transformer health monitoring solutions. This patented technology provides precision H₂ concentration measurement directly in the oil, providing transformer owners including municipalities, utilities, and others with real-time indications of potential faults and issues within their transformer fleet. The sensor’s unique auto-calibration feature means no maintenance needed for over 10 years, making the GRIDSCAN 5000 the lowest total cost of ownership sensor on the market.

FM Approvals is the independent testing arm of international insurance carrier, FM Global. FM Approvals uses scientific research and testing to ensure products conform to the highest standards for safety and property loss prevention. Products that pass this stringent testing receive the FM APPROVED mark.

“The recognition of being the first company to receive FM Approvals is a strong, independent acknowledgment of the value our GRIDSCAN 5000 brings to the market,” said Dave Meyers, CEO and President of H2scan. “It is H2scan’s mission to equip transformers with safe, affordable, and effective H₂ sensing technology, and the GRIDSCAN 5000 is an integral part of that vision. Having a FM Approved monitoring sensor helps asset managers accelerate their decision-making process when tasked to select the right H₂ monitor.”

Proven performance for critical industrial applications

The FM Approval process includes a comprehensive set of tests including temperature, vibration, repeatability, high concentration, and voltage variation tests – all of which are specified in FM Approvals FM6250 standard. They also include low-range and full-range accuracy tests, in transformer oil in H₂ concentrations of 25 ppm, 100 ppm, 200 ppm, and 250 ppm, as well as 0%, 25%, 50%, 75%, and 90% of the full range, respectively.

This approval demonstrates H2scan’s leadership and continued innovation in the transformer market as the need for reliability and resiliency becomes more important for the power industry. Additionally, as the H₂ economy evolves, the company’s mission is to positively impact the future of H₂ safety and reliability globally as the world decarbonizes. As energy needs shift around the world towards H₂ solutions, H2scan aims to equip its customer with safe and cost-effective sensing technology to improve the operations of transformers, battery rooms, electrolyzers, fuel cells and much more.
