    REVIEWS

    “Bob is more interested in the subject matter and the science behind his products than in making a sale. He wants to make sure that a solution will work for us. Beyond their products, RH Systems will continue to innovate and amaze the humidity community with new systems and instruments that will advance the metrological community.”

    Tee Yee Zheng Supertron Sensing

    RH Systems helped me understand the systems better. That makes me ask better questions and ultimately become a better technologist. They show that their customers are clearly everything. From the way they treat us, you can tell that people must absolutely love working there.

    Paul Gomez Sandia National Labs

    “Bob and the staff at RH Systems are the greatest and their undying devotion to supporting the community is greatly appreciated. They are prepping the next generation of professionals in our community for a continuation of support unparalleled in temp and humidity and should be a beacon for all metrology.”

    Joseph Rindone Metrologist at Paladin Metrology Advocates

    “RH Systems goes the extra mile, without fail. And they stand behind what they do. Customer service is a dying art. RH Systems still gives you one-on-one attention and they always pick up the phone. In our industry, we have a lot of red tape. Bob helps us navigate this and wants to take on the challenge of forming a custom solution. He is invested in what his customers need. That speaks volumes.”

    Roger Free Calibration Technician at Haleon

    “RH Systems has created the best frost point generator in the world. The G3 is very fast, has high precision and is still very easy to use. The three separately flow-controlled outputs give you maximum flexibility when connecting measuring devices.”

    Helmut Hager CEO, Techmetrics

    “I’ve never met anyone who wants to do more than what his customers expect than Bob. I respect and admire that philosophy so much! You will never regret doing business with Bob Hardy!”
