1. The density era is divided into meaningful ranges: 600 – 950 // 900 – 1200 // 1100 – 1500

   The viscosity era is divided into meaningful ranges: 0.3 – 10 // 3 – 80 // 10 – 200

2. Indicated performances have been obtained in controlled laboratory conditions using sensor’s digital output. In practice, additional inaccuracy might arise due to application’s conditions, use of the analog mode, fluid characteristics…
