COMBINED INDOOR/OUTDOOR MONITOR


High quality particle monitor PMX for ventilation and air purification systems.
The combined indoor/outdoor PMX Particle Counter is designed for environmental monitoring in industrial, commercial and institutional buildings.

The unit provides accurate readings of particle counts in two important sizes, 2.5μm and 10μm. The sensor uses the laser light scattering method which is not subject to drift or sensor contamination.

A fixed volume of air is pumped through the sensor and suspended particulate matter in a given unit volume of air is totalized into two bins, one for particles of 2.5μm and another for larger 10 micron sizes.

The results are reported in μg/ m3 of air with all data available over the RS485 port for integration into large systems using either the BACnet MS/TP or the Modbus RTU protocols,with an Ethernet port.

Analog outputs, one for each of the two particle size bins.

The World Health Organization and the European Union aim to decrease particle loads to less than 50μg/m3 as an average over 24 hours.

There are workplaces today where the average reaches 200-500μg/m3.

The Indoor Monitor converts measurements of particles to mass per cubic meter by assuming the particle intensity.

PMX is used to indicate the amount of particles or dust.

For increased security monitoring, you can if necessary, install a separate ozone detector in the room to get a better overall overview.
