Clean room environmental monitoring that keeps your cleanroom in control
Certification shows a cleanroom met its class on the day of testing. Environmental monitoring shows it stays in control every day in between. We help you set up, verify and support the monitoring that protects your process.
Monitoring between certifications
A cleanroom can drift out of control between annual certifications without anyone noticing. A filter may begin to leak, a door closer may weaken, or HVAC changes may alter room pressures. Environmental monitoring catches these changes early through regular, planned measurements.
A typical programme defines what is measured, where, how often and against which alert and action limits. Physical parameters such as non-viable particle counts, differential pressure, temperature and humidity are monitored alongside any microbiological sampling carried out by your own quality team.
Many facilities use fixed sensors connected to a monitoring system, supported by periodic portable measurements. The fixed sensors themselves need regular calibration, otherwise the system may show reassuring readings that are simply wrong.
Monitoring works hand in hand with formal ISO 14644 cleanroom classification and clean room certification, which set the baseline that monitoring protects.
Catch drift before it becomes a failure
Continuous assurance
Routine data shows the room stays in control, not just on certification day.
Faster investigations
Trend data helps teams find the cause of excursions quickly.
Audit evidence
Inspectors expect documented monitoring with defined limits and reviewed results.

Where monitoring matters
Choosing where to monitor
Monitoring locations should reflect risk. Points close to exposed product, critical work zones, doorways between classes and areas where air may stagnate are usually given priority. Classification data and airflow visualization studies help identify these positions objectively.
Locations should be documented with drawings so the same points are sampled each time. Consistent locations make trends meaningful and help teams see real changes rather than differences caused by moving the sampling point.
Setting limits that work
Alert limits give an early warning that conditions are moving away from normal. Action limits trigger investigation and corrective action. Limits are often based on the room's class, historical data and the risk to the process.
Reviewing limits periodically keeps them meaningful. Limits that are never reached may be too loose; limits that are reached constantly may be unrealistic or point to a genuine problem that needs fixing.
Calibrating your monitoring sensors
Fixed particle counters, pressure transmitters and temperature and humidity probes form the backbone of most monitoring systems. Each should be calibrated on a defined schedule, with as-found and as-left results recorded, so the data your team reviews every day reflects real conditions.
