OHS 40 Digital Overhead Stirrer Velp Scientifica

OHS 40 Digital Overhead Stirrer Velp Scientifica

Product Description

The OHS 40 Digital overhead stirrer is designed for laboratories that require reliability, safety, and efficiency in their stirring applications. Built with a sealed housing and rated IP 54, the instrument ensures durability even in demanding and aggressive working environments.

To guarantee maximum safety, the OHS 40 Digital is equipped with integrated overload, overtemperature, and overcurrent protection alarms that automatically stop stirring when necessary. The safe start/stop knob and lock function further reduce the risk of unintended operation or accidental setting changes.

Delivering up to 40 Ncm torque with a stirring capacity of 25 liters, the OHS 40 Digital is perfectly suited for low to medium viscosity applications with precision and stability.
