Particle Measuring Systems is proud to be a sustainable business. As part of the Spectris group we have set a leading ambition to achieve Net Zero across our value chain, including all Scope 1, 2 and 3 emissions. In support of this ambition, we have set the following targets:
- Our Operations - We commit to reducing absolute Scope 1 and 2 emissions by 85% by 2030 from 2020 and achieving Net Zero by 2030: and
- our Value Chain - We commit to reducing absolute Scope 3 emissions by 42% by 2030 from 2020 and achieving Net Zero by 2040.
Both targets are aligned with latest climate science and the Paris Agreement’s goal to limit global warming to 1.5oC above pre-industrial levels.
We have submitted both targets to the Science Based Targets Initiative for validation.
In support of these targets, we are:
- Aligning with the RE 100 initiative and committing to sourcing 100% of our global electricity from renewable sources by 2030;
- Aligning with the EV 100 initiative and committing to a 100% electric global fleet by 2030;
- committing to zero waste to landfill by 2030 across our global operations; and
- Accelerating our focus on product efficiency and product circularity.
A full roadmap of our Net Zero ambition can be viewed here.

Why Choose Particle Measuring Systems
Particle Counter Experts
Experts in Particle Counting Contamination Monitoring Solutions Since 1972 with presence around the globe
Superior Particle Counting Knowledge
Particle Measuring Systems (PMS) is the inventor of laser based-particle counting, and we continue to lead the field with our dedication to hiring and training industry professionals. Our experts are recognized as thought leaders, evidenced through our speaking requests, webinars, authored papers and high education levels.
Our technology experts actively participate with customers and industry standards committees to understand the evolving needs and challenges faced by our broad customer base. Our renowned Particle College® program includes a two-day series of lectures and hands-on labs covering basic particle measuring concepts to advanced applications of contamination monitoring and control.
Superior Particle Counting Technology
A core investment in research, engineering and product manufacturing has resulted in more than 60 patents related to our products and applications. We create the technology that enables you to make fact-based decisions, improve yield process, and comply with changing regulatory requirements such as Annex 1, ISO 14644-1, USP 788, USP 797, 21CFR Part 11, and more. Our technology can measure particle sizes as small as 20 nm in water and chemicals, 10 um in air, and molecular contamination concentrations in parts per trillion. We are also leaders in microbial monitoring developing traditional techniques that reduce false positives.
Superior Particle Counter Quality
Particle Measuring Systems sets the standard for contamination monitoring by first designing reliability into our particle counters and then backing the technology with an unmatched Quality Management System.
Our service technicians are well trained to calibrate your instruments to the highest standards, and our software-controlled approach automates critical steps that drive consistency in each calibration. This ensures the same calibration results and performance, consistent with factory calibration, regardless of where the calibration is performed- anywhere in the world.
All calibrations are completed in strict accordance with ISO guidelines. PMS provides an unequaled counting efficiency test for first-channel sensitivity. For pharmaceutical applications, particle counters must be calibrated to the exacting standard of ISO 21501-4:2007, which includes measurements to verify and set flow rate, counting efficiency, particle sizing, resolution, signal ratios and zero count. Each calibration is also completed using NIST-traceable standards, and a certificate is provided with each calibration
At Particle Measuring Systems (PMS), as a global leader in contamination monitoring, we have been actively monitoring and reducing our environmental contamination over the last few years.
As part of our Corporate Social Responsibility (CSR) approach we have installed electric car charging stations on site, put in an ultra pure water (UPW) recycling system (that saves approximately 40% of UPW water use), and actively participate in Boulder’s zero waste program including implementing a composting program and training all Boulder employees.
Past CSR initiatives have included installing new lighting that reduces wattage used, eliminating white room air handles, and implementing a comprehensive recycling program that includes electronics. Areas where lighting has been changed have had a 41% reduction in watts used. The change was made my removing T-12 lighting and replacing it with T-8 high efficiency lighting.
The white room air handlers that PMS used in the past accounted for 17% of the building’s total electric bill. PMS was able to remove them and retrofit the space to deliver tempered air without them, with no additional energy consumption.
Since January 2013, Particle Measuring Systems has sent 21,550 pounds of electronics and parts/materials to a responsible electronics recycling company that de-manufactures electronics, and separates the components by category. The items are then recycled and kept out of the land fills. PMS also recycles office paper on an individual basis as well as cardboard.
“We are participating in all these programs for several reasons,” said John Mitchell, President of Particle Measuring Systems, “it is the right thing to do, it saves us money, and it supports our employees and the environment”.
