OHS 200 Advance Overhead Stirrer Velp Scientifica

OHS 200 Advance Overhead Stirrer Velp Scientifica

Product Description

The OHS 200 Advance is VELP’s high-end overhead stirrer, engineered to deliver superior performance and maximum safety in demanding laboratory environments. Its robust sealed housing with an IP 54 protection rating ensures durability even under aggressive working conditions.

Safety is at the core of the OHS 200 Advance. Integrated overload, overtemperature, and overcurrent alarms protect the instrument and your samples by automatically stopping operation when necessary. The safe start and stop knob, combined with a locking function, prevents unintended operation or parameter changes.

Equipped with an innovative vibration sensor, the OHS 200 Advance detects improper setups and halts operation to ensure secure and stable stirring.
