The LHA-01 is a single-channel high-pressure syringe pump equipped with a high-definition LCD touchscreen for operation. It can deliver a linear thrust of >200 lbs (91 kg) within a broad flow rate range and supports five operational modes, including injection and withdrawal. It incorporates RS485 communication, supports the Modbus protocol, making it highly versatile and easy to integrate into a range of liquid transfer applications.
Functions and Features
- 4.3" color LCD displaying transfer volume, remaining volume, flow rate, direction of operation, syringe size, and more.
- Animated display of operating status.
- Compatible with a wide range of syringe sizes (0.5μl to 140ml)
- Linear speed from 1μm/min to 190mm/min for precise control over liquid transfer rates.
- Features snap-on stainless steel syringes for high-pressure or viscous liquid transfer.
- Ensures accurate and stable injection even for highly corrosive or viscous liquids.
- Power-down memory function for easy resumption after a power failure.
- Allows programming without the need for a PC.
- Equipped with RS485 communication and supports Modbus communication protocol.Â
