Hydrogen concentration monitor HWMS-PSW series
A hydrogen concentration monitor is used to monitor dissolved hydrogen concentration in a hemodialysis system using dialysate containing hydrogen (H2) (developed product).
This device (hydrogen concentration monitor) is used to monitor the dissolved hydrogen concentration in a hemodialysis system that uses dialysate containing hydrogen (H2).
This hemodialysis system differs from conventional dialysis systems in that it uses electrolyzed dialysis water that contains a large amount of dissolved hydrogen in the dialysate. As a result, the dialysate produced by this system has a characteristic that a certain amount of hydrogen gas is dissolved. Pureron Japan is developing a monitor to measure the hydrogen concentration of this system.
*The development of this device (hydrogen concentration monitor) was supported by the Fukushima Medical and Welfare Equipment Development Project Subsidy.
The hydrogen sensor used in this monitor is a sensor manufactured by NAST Co., Ltd.

Features
Dissolved hydrogen concentration can be measured continuously by supplying hydrogen water at low pressure (with a built-in pump, measurement is possible even with no-pressure water supply). After measurement, the wastewater is discharged without pressure.
