Velp Scientifica OHS 200 Advance Overhead Stirrer

The OHS 200 Advance is the ideal solution for demanding applications operating with viscosities up to 100.000 mPa. The electronically controlled brushless motor of the OHS 200 Advance stirs up to 100 l with a maximum torque of 200 Ncm and ensures the longest lifespan.

Safety and Resistance in the Lab

• Resistant sealed housing with IP 54 Protection Rating guarantees durability even in the most aggressive environments
• Integrated overload, over-temperature, and over-current safety alarms preserve performance over time by stopping the stirring
• Safe start and stop knob operation with lock key prevents unintended start-up and changes in the working conditions
• Integrated vibration sensors with different levels of sensitivity will stop the operation and inform users when OHS is stable and properly fixed

Best-in-Class Stirring Power

• Ideal for demanding applications operating with a range of viscosities
• Electronic-controlled, brushless motor stirs with a maximum torque
• SpeedServo™ torque compensation technology keeps the speed constant automatically adjusting to viscosity changes
• Two-speed gears provide the best performance for both high torque and high volume operations
• Electronic speed control can be manually set to desired rpm
• Torque remains stable throughout the whole speed range which is a crucial parameter for reproducibility

SmartChuck™ Simplifies Shaft Accommodation

• The shaft accommodation process can be carried out with one hand and does not require any tools
• With two simple operations, unlock the protection ring to drive the shaft in and out with maximum ease
• Opening the ring during the stirring process will automatically block the analysis and the instrument informs the user of maximum safety

Intuitive and Precise

• 3.5 in. TFT Display will guide users to precisely set working conditions and get reproducible results
• Displays main information at a glance together with torque measurement for real-time information on viscosity change with a resolution of 1 Ncm
• Interact with the OHS Advance from the real-time graph showing speed, torque, and temperature
• OHS Advance Stirrers work unattended thanks to a timer which can be set from 1 min. to 99.59 hr.
• Define and program operating methods that are ideal for demanding tasks where ramps and interval operations are required

OHS Advance Connectivity Advantages

• OHS Advance are the only overhead stirrers to offer the possibility of controlling and monitoring processes through a Wi-Fi connection
• VELP Ermes cloud platform allows to control the OHS Advance from PC, smartphone, and tablet through a simple and intuitive web interface
• Activate stirring, set a timer, set a method (among those saved on the device), or download and share reports with a click
• VELP Ermes can manage OHS Advance located in clean rooms or other controlled environments, without the need for long safety procedures
• OHS/CotrollerSoft™ software offers all labs a valid alternative with USB connectivity for those who cannot benefit from cloud services
