Our pressostats, manometers and differential pressure transmitters keep a watchful eye on the clogging and fouling of AHU filters. Continuous monitoring of these filters ensures preventive maintenance of air handling systems.

Our electronic transmitters designed to monitor filters are versatile and ultra-reliable. They can trigger visual and audible alarms, and send their measurements to the building management system. In addition, some have an auto-zero mechanism for constant accuracy over time.

Our portable differential pressure measurement instruments can be used to carry out the frequent checks required on filtration systems. Certain models with modular probes allow other types of measurement (flow, temperature, etc.).

Portable and reliable, our instruments are there to meet all the needs of technicians performing air handling unit checks, inspections and commissioning. From the pocket micromanometer to the multifunction instrument, all variants are available to meet every type of task.

Compact and fully autonomous, our differential pressure data loggers continuously monitor filter clogging. The real-time display allows visual inspection of the measured values, optimising maintenance operations.

Easy to install and secure, our lithium battery-powered units record differential pressure for several years - so you can rationalise filter replacement by analysing the way they clog up. The Tracklog version communicates over long distances and can send alerts by SMS/email (LoRa).

Backed by 45 years of expertise in metrology, our metrological technicians come to your site (France only) to calibrate your instruments without service disruption for the majority of air parameters, whatever the brand of your sensors.

For more specific requirements, our twenty metrology experts calibrate all brands of equipment in our French laboratories for all air parameters (Cofrac ISO 17025 accreditation for temperature and hygrometry in Montpon).
