MoDeL H-3553Bubbler/Pressure Sensor
The WaterLoG® Model H-3553 is a combined Bubbler with built in Pressure Sensor. The Pressure sensor is a NIST traceable pressure sensor. The sensor directly measures dry gas with accuracy better than 0.02% FSo.
Combining high accuracy and low cost. The H-3553 provides the highest purge pressure in the industry at 90 psi.
