HGC – Humidity Generator and Controller

Part Number: HGC

The HGC Series offers standalone humidity generation and precision control (5 %–90 % RH) for small to mid-sized environmental chambers, including those used in DataPhysics OCA and other systems. Equipped with an integrated pump, desiccant system, heated reservoir, and touchscreen interface—or controllable via SCH 20 software—the HGC ensures reliable humidity delivery without needing compressed gas. These units support research, quality control, and humidity-dependent testing across a variety of scientific and industrial applications .

                                                
                                                    Compact and Fully Stand-Alone Humidity Control                                                
                                            
                                                Generates precise relative humidity (5 %–90 % RH) using only ambient air—no external gas or dry-air supply needed. Features heated reservoir and gas line to prevent condensation .
