We’ve been pioneers of sensing innovation for
over 55 years

What began as a bold idea in 1969 has grown into a global enterprise, transforming pressure signals into an immeasurable impact on MedTech.

Turning Clinical Insights into Life-Saving Innovations

It only takes one breakthrough to save a life. For over 55 years, Millar has empowered clinical trials and OEM innovation with precision pressure sensors that deliver intelligent insights — driving smarter devices, better outcomes and life-saving impact.

Revolutionizing Agriculture Management with Advanced pH Sensors

Millar’s ISFET pH sensors deliver accurate, real-time data to optimize agricultural monitoring and decision-making. Engineered for reliability in harsh environments, they help improve efficiency, increase yields and support sustainable agriculture through precise, durable measurement solutions.

Optimizing Production with High-Precision Sensors for Food and Beverage

Millar’s advanced sensor technology delivers accurate, real-time pH data for brewing, dairy and food safety. Our durable, glass-free ISFET sensors perform reliably in tough conditions, helping manufacturers optimize production and maintain consistent product quality and safety standards.

Real-Time Water Quality Data for Environmental Monitoring

Our integrated ISFET pH and EC sensors deliver precise, real-time measurements for wastewater and ocean monitoring devices. Built for harsh conditions, they reliably track key water parameters, including pH, conductivity, ORP and temperature, to help protect ecosystems and ensure compliance with environmental standards.

End-to-End Contract Design and Manufacturing (CDMO)

1

Discovery

Millar’s feasibility studies determine the best sensor integration solution for your device. Leveraging our extensive sensing technology expertise, this initial testing and analysis phase identifies potential issues early in the development process, eliminates unnecessary costs and delays, and gains insight into project scope and future manufacturing requirements.

2

Proof of Concept

The proof of concept phase involves product customization to test full sensor integration into one or more working designs. The Millar OEM team explores multiple design iterations before selecting and refining a final design, then develops initial documentation.

3

Prototyping Development

Millar supports early-stage prototyping in our ISO 13485-certified manufacturing facility and ISO Class 7 clean room. Our goal at this stage is to establish a stable design, complete key design control documentation, and define production volume requirements.

4

Manufacturing Development

Millar’s manufacturing development phase defines the critical processes that impact a device’s overall cost and successful production. Our manufacturing engineers will begin process validation work and review the designs and components to determine the product’s ease of fabrication, possibly suggesting modifications to maximize production yields.

5

Design Validation

Our engineering and production teams work closely to develop pilot builds, perform design verification, and ensure systems are ready for testing. With full-scale manufacturing capabilities, including our ISO Class 7 clean room, we’re equipped to produce sensor-integrated components that meet the highest standards of quality and performance across all applications.

6

Clinical Trials (for Medical Devices)

Once your device is validated for performance and safety, it advances to clinical trials. Millar supports this critical phase with production-quality builds, thorough documentation and regulatory expertise — ensuring your device meets the stringent requirements for human use and is ready for real-world impact.

7

Device Commercialization

Millar is your CDMO partner every step of the way. Once your medical device is in commercial production, we provide sustaining engineering services to ensure production lines are optimized. Services include general maintenance, process improvements and a dedicated team to facilitate any future changes or challenges.
