Level probe (stainless steel)
Item number: LMK 387H Price on request
Delivery time:Delivery time on request
The LMK 387 stainless steel submersible probe was designed for level and gauge measurement in wastewater, sludge or riverbeds. The mechanical robustness of the flush ceramic diaphragm facilitates easy disassembly and cleaning of the probe. The outer diameter is only 22 mm, which means that installation or retrofitting in 1\" pipes or in confined installation conditions can be carried out without any problems. An intrinsically safe version (zone 0) is also available.
