Microammeter map to fix from -50 to 50µa

The MAP microammeter measures the very low intensity of the flame sensing and UV cell current in gas burners, fuel burners, blue flame, with flame sensing probe. Checks functionning state of flame detection device. By flame sensing (burner with electrode). By UV cell. Range of -50?A/0?A/+50?A, Its zero allows measurement even if the connection of wire is reversed. The wire line up in the case. A microammeter is installed in series that is on the same line as the probe or the cell to be measured. Device to embed in a cabinet. Dimensions : Width 61mm Height 48mm Deepth 45mm Embedding 38mm Electrical connections screw 4mm Supplied with fixing screw and nut.
