Safe Living Technologies

We Make The Invisible, Visible ®

As an Electronics Engineering Technologist, Rob Metzinger – SLT’s President and Founder – became extremely concerned about the interference of man-made electromagnetic fields (EMF) on the human body. Rob’s interest in EMF began in the year 2000, and Safe Living Technologies (SLT) was founded in 2006 – a time when wireless technology was beginning to boom, and without any caution or restraint.

Rob furthered his education to become certified as a Building Biology Environmental Consultant (BBEC) and an Electromagnetic Radiation Specialist (EMRS) through the Building Biology Institute. He has been an educator and course developer in the advanced studies of EMF/EMR since 2008. He strives to be a leader in the field of education and advocacy around this complex issue.

An alarming number of recent studies indicate that electrosmog has negative biological impacts. See our studies page and the Bio-Initiative Report for further details. It is in our best interest to minimize exposure to these invisible forces as much as possible.


Welcome to Safe Living Technologies (SLT). We are all about detection & mitigation of EMF. We offer top-of-the-line products to help you find EMF sources & intensities, along with tested & certified products to help you shield against them. We even have our own product line – the Safe and Sound series of RF meters and accessories – which are all tested and backed by scientific research. SLT firmly believes in the verifiable proof of measurements.

Our Safe and Sound Pro II RF Meter has been selected by world-renowned environmental toxicologist Dr. Magda Havas for her Global RF Project, launched in March 2021. Please check it out; volunteers are needed for community-based research.

Based in Guelph, ON, Canada (west of Toronto), we are committed to providing the highest standards of customer service, and will take the time to individually assist each one of our clients. We have successfully helped thousands of electrically sensitive people over the years.

We work hard to keep SLT positioned as a leader. Our team includes three EMR technicians, and partnerships with industry-leading suppliers & distributors. Not to mention our strong relationships with doctors, EMF/EMR organizations, scientific researchers, and other professionals in the field.

We are here to help.
