WT300S(New) Large Torque Speed-Variable Peristaltic Pump

WT300S Speed Variable Peristaltic Pump is an upgraded new product launched by Lead Fluid based on the original WT300S according to market demand. The product uses a Cortex M3 core processor, runs faster, and has higher speed accuracy of the device. The display is upgraded from digital tube to LCD display, Chinese and English display, more intuitive. The new deceleration function makes the device run more reliably, and the RS485 communication adds more settings to the MODBUS to meet the requirements of different communication devices. The WT300S Speed Variable Peristaltic Pump can also be connected to a thermal printer to print the running parameters of the device. It can also automatically switch the external analog speed signal type (voltage or current) from the control panel, which is more convenient and fast.
