The LHA-01 single-channel high-pressure syringe pump is designed for precise and high-force fluid delivery, accommodating syringes ranging from 0.5 μL to 140 mL with a flow range of 3.06 pL/min to 215 mL/min. Its high-definition LCD touchscreen enables intuitive parameter configuration, precise monitoring, and easy selection of five operational modes, including injection and withdrawal. The pump ensures reliable high-precision performance and incorporates protective features and an integrated alarm system. External signals can control the pump’s start/stop functions via the built-in RS485 communication, supporting the MODBUS protocol, making it versatile and easily integrated into various liquid transfer applications.
