NETHERLANDS
The Consilium Salwico ST400 H2S gas detector, art. no. 4462, measures hydrogen sulphide over a 0-30 ppm range and belongs to the toxic gas side of a ship’s gas detection system. Placed in areas where sour gas or decaying organic matter can build up, it acts as the sensing point that tells the gas detection plant how much H2S is present. The detector is of Butox type ST401EC, rated for -40°C to +60°C ambient, with input parameters of Ui=28 V, Li=93 mA, Ci=30 nF, Li=1 mH and Pi=0.75 W. It is supplied in used condition.
