Plantower laser counters may need replacing for various reasons including age, contamination inside the device or simply failing after a long time in service.

simple and well-guided operation

I have installed 5 PurpleAir sensor stations in the municipality of Pignataro Maggiore (Italy) and over the years, I have had to replace 4 pairs of sensors, following the provided video guide. The operation is simple and very well-guided!
