Mescomp offers only extended scale logarithmic gauges from the renowned Italmanometri and Wika companys. Each package has a certificate of quality control and confirmation of the accuracy of the supplied pressure gauges. We import special pressure gauges. The thread and the entire internal measuring device is made of stainless steel AISI 316 and resistant against fertilizers and other aggressive pesticides. Manometers made of AISI 316 can be easily distinguished from those that are damaged after contact with the fertilizers. In our pressure gauges, the connector visible on the outside is steel color.
