More About this Item
The Testo refrigeration system analyzers introduce the use of digital measurement technology with highly accurate sensors, to set new standards in precision and assurance of measurement. The digital display guarantees that readout errors are eliminated in the future. The risk of inaccuracy in reading analog displays is always present, caused by the so-called parallax error, i.e., the respective angle sight has an effect on the result read. Frequent vibrations can also make reading the display additionally difficult. Vibration tests according to DIN/EN 50379 guarantee the functionality of the construction of these analyzers far beyond the demands of day-to-day use, and the analyzers have IP54 protection for water resistance.
