Ease of use

This is excellent. I had previous assumed that most bad air is generated locally but this device indicates that even in very rural areas the air can be v bad, depending on drifts from the continent. Helps me determine when to exercise and when not

This was the perfect unit. It could easily be set up, and re-set to factory settings. The results were clear to see. The results led to a theory that air pollution is to be found in enclosed places where human carry out their modern lifestyles. Its a bit worrying to find my office needs the window opening more. Great unit, good price

Excelente medidor. Funciona muy bien y fácil de usar. Si requieres exportar los datos de las lecturas a una computadora, es necesario comprar la versión con data exported function. La batería dura solo 4 horas pero se puede conectar directamente a la corriente.

I have air problems at my place of God, lots of people coughing when a/c unit comes on. I install a/c for a living,
over 38 years. I tell the elders there is a problem with the a/c, this goes on for about 3 months. So I buy this meter and test it at home, than a large hall. The meter show how air went from ok to very bad on all levels. Now they can see it, co2 levels high, particles high and turning on the a/c did not help. The unit had major problems with. I would buy meter again
