Chemical-Compatible Micro Liquid Level Sensor for Harsh Environments¹

Product Description Product DescriptionLLD-Liquid Level SensorLLD primarily tackles empty aspiration and needle collision issues. It measures liquid level height by calculating capacitance, enabling users to determine pipette tip descent height and track liquid levels. It can also connect to an external optocoupler to trigger alarms upon needle collision, preventing tip damage and ensuring precise liquid handling.LLD can effectively solve the problems of empty suction and probe collision during automated pipetting.  Product ParametersLLD LIQUID SENSOR SPECIFICATIONMeasuring Range+16pFMin.
