OHS 100 Advance Overhead Stirrer Velp Scientifica

OHS 100 Advance Overhead Stirrer Velp Scientifica

Product Description

The OHS 100 Advance is a premium overhead stirrer from VELP designed to provide excellent performance and the highest safety standards for laboratory mixing operations. With a sealed housing and IP 54 protection rating, it is built for durability and reliable operation even in harsh environments.

The system integrates multiple safety features, including overload, overtemperature, and overcurrent alarms that protect both the instrument and samples by automatically stopping operation when necessary. The safe start and stop knob, together with the locking function, prevents accidental start-up or changes in working conditions.

For enhanced stability, the OHS 100 Advance is equipped with an integrated vibration sensor with adjustable sensitivity, which halts operation if improper setup or instability is detected.
