Spesifikasi Koehler K48290 Hydrogen Sulfide Apparatus

Test Method


For the detection of hydrogen sulfide in liquefied petroleum (LP) gases. The sensitivity of the test is about 4 mg/m3 (0.15 to 0.2 grain of hydrogen sulfide per 100 ft3) of gas.


Specifications


Conforms to the specifications of: 


ASTM D2420, ISO 8819 


Temperature Range: +5 to 150°C


Temperature Control Stability: ± 0.05°C


Temperature Readout Accuracy: ± 0.5°C


Bath Capacity: 28L (7.3gal)


LPG Cylinder Capacity: 500mL


Flow Meter Range: 2 – 3 L/min


Thermometer Range: -5 to +110°C


DescriptionVaporized LP gas is passed over moist lead acetate paper under controlled conditions. Hydrogen sulfide reacts with lead acetate to form lead sulfide which produces a coloration on the paper varying from yellow to black, depending upon the amount of hydrogen sulfide present. Liquefied petroleum gases and their products of combustion must not be unduly corrosive to the materials with which they come in contact. The potential personnel exposure hazards of H2S also make the detection and measurement of hydrogen sulfide important, even in low concentrations. In addition, in some cases the odor of the gases must not be objectionable.
