Building Trust Through Excellence: What Our ISO Audit Success Means for You

At OTT HydroMet, quality, safety, and sustainability are more than internal goals – they are promises we make to our customers every day. That’s why we’re proud to share a major milestone: the successful completion of our ISO 9001 surveillance audit and our first ISO 14001 multi-site certification audit – both with zero findings.

“The fact that our Lufft brand has been ISO 9001 certified for 30 years now is a strong testament to our enduring commitment to quality and customer satisfaction,” says Nadia Iannuzzi, Managing Director at OTT HydroMet. “With the addition of ISO 14001, we’re taking the next step: We are proving that we not only meet the highest standards in quality but also take responsibility for a more sustainable future.”

Confidence in Quality: ISO 9001 Multi-Site Certification

OTT HydroMet has been ISO 9001 certified since 1995, starting with our Lufft site in Fellbach. Since 2021, we’ve held a multi-site certification that includes our locations in Fellbach, Sterling, Kempten, and Delft. This long-standing commitment to quality management ensures that our processes are designed to deliver consistent, reliable results across all sites.

The ISO 9001 standard is based on key principles such as:

• Customer focus
• Leadership
• Engagement of people
• Process approach
• Continuous improvement
• Evidence-based decision making
• Relationship management

Our certification, audited by NSAI (National Standards Authority of Ireland), confirms that we:

• Operate a structured and effective Quality Management System (QMS)
• Consistently meet customer and regulatory requirements
• Continuously improving our processes and performance

A zero-finding audit means our systems are not only compliant but also robust and proactively managed – reducing risk for our customers and partners. It’s a clear signal that when you work with OTT HydroMet, you’re choosing a partner who delivers quality you can count on.

Commitment to Sustainability: ISO 14001 Multi-Site Certification

This year, OTT HydroMet also successfully passed the multi-site ISO 14001 audit for the first time. This is a major milestone, especially for a company whose mission is to monitor and protect the environment.

ISO 14001 is the leading international standard for Environmental Management Systems (EMS). It provides a framework for:

• Reducing environmental impact
• Complying with environmental laws and regulations
• Continuously improving environmental performance

For us, this certification is more than a badge – it’s a proof point that we live our mission:

To provide decision-makers with vital, trusted data through innovative hardware, software, and services – to protect lives, the environment, and infrastructure.

In our industry, credibility and sustainability go hand in hand. With ISO 14001, we demonstrate that:

• We actively manage and reduce our environmental footprint
• We are committed to continuous improvement in sustainability
• Our customers can trust not only in our products and services, but also in our responsibility for a better future

“One example of our commitment to a greener future is that all sites are now running on renewable energy sources,” says Tamara Poessnecker, Global Quality & EHS Director at OTT HydroMet. “We’ve also redesigned the packaging of some products to be recyclable – a small but meaningful step toward reducing our environmental impact.”

This certification reinforces our role as a responsible leader in environmental monitoring—and strengthens the trust our partners and customers place in us every day.

What This Means for You

In today’s business landscape, certifications like ISO 9001 and ISO 14001 aren’t just checkboxes – they’re strategic assets. They show that we’re not only compliant, but also committed to building a resilient, future-ready supply chain that aligns with your values.

Whether you’re a long-time partner or exploring new collaborations, we want you to know:
Your success is our priority.

These certifications are just one way we prove it.
