1.2 ISA-44RAH-OD

The ISA-44RAH-OD is designed to monitor breathing air from cylinders at pressures up to 5000 psi. The

equipment consists of an ISA-44RAL-OD with the addition of a high pressure regulator at the sample air input as

shown in Figure 1a. The high pressure regulator must be plugged into the high pressure line with an appropriate

fitting; the output is connected to the ISA-44RAH-OD by means of a quick release pneumatic fitting. The

operation of the ISA-44RAH-OD is identical with that of the ISA-44RAL-OD, and calibration is also identical; the

high pressure regulator is removed from the sample input and the calibration procedures given in this manual are

employed.
