As well as gauges with the two-chamber system, EPHY-MESS offers oil level gauges with one window in brass, aluminium and stainless steel housing. The special protection glass used is guaranteed fully leak-proof and has a high resistance to any kind of oil. The oil level gauges made of aluminium provide a cost effective alternative and are ideal for use in applications, where weight limits are important. Stainless steel oil level gauges are common in industrial applications because of their corrosion resistance and mechanical stability. All versions are available with various threads (see the table).
