Features of EHN-YN series

High resolution
Like EHN-R series, thanks to digitized controller, stroke speed can be adjusted 1 spm step from 1 – 360 spm. Combined with stroke length adjustment, you can do the fine adjustment from very small flow to maximum flow rate.
Multi-voltage power source
Multi-voltage power source from AC100 – 240V for al model. You are now free from worrying about power voltage.
Air vent valve
Small flow capacity models (EHN-10, 15, 20) are equipped with air vent valve. Air in the pump chamber can be easily released by simply turning the knob.
Flow checker support feature
Flow checker FCM support feature was added to the features of conventional EHN-Y series. Because of this, models equipped with flow checker FCM support type are added to the line up.
