PMS™ Service Repair & Calibration

PMS™ Repair & Calibration

Our service technicians are well trained to calibrate your PMS instruments* to the highest standards and our software-controlled approach automates critical steps that drive consistency in each calibration. This ensures the same calibration result and performance, consistent with the factory calibration, regardless of where the calibration is performed—anywhere in the world.

PMS Calibration Services include:

  • Calibration and verification/validation and adjustments back to
    factory standards

    • ISO 9001:2015
    • ISO 17025
  • Calibration certificate issued with each instrument
  • Preventative maintenance
  • Technical and software support
  • Instrument examination (as found and as left data available)
  • NIST traceable

We offer a broad range of services designed to reduce costly downtime. Please contact us for information regarding the following services:

  • On-site calibration at your facility
  • Dedicated Particle Measuring Systems technician year-round at your facility
  • Service contracts for on-site service and return to factory service

Aerosol particle counters must be calibrated to the exacting standard of ISO 21501-4:2018 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 of calibration is provided with each calibration.

We’re here to help; hear it from our customers:

We had an issue with our liquid particle counter last week and I couldn’t have asked for more
from PMS Customer Service. When troubleshooting, they realized this was not an issue they’ve
seen before. Rick H, who was on vacation at the time, took the time to accommodate not only the
issue at hand, but he worked around our availability. A big thank you goes out to Rick and the
entire Customer Service Department. Thanks again for your assistance!

I’m the Metrology Supervisor here at (confidential). Rob Carter is our Field Service Technician

last few years. He provides great communication prior to his arrival and daily while on-site. He
is very knowledgeable in answering any questions we have and also in calibrating/repairing
equipment. He is always on time and works efficiently to service our equipment in a timely
manner. It is a pleasure to work with Rob and I look forward to working together for years to
