Features:
- The resistant sealed housing and the IP 54 Protection Rating guarantee durability even in the most aggressive environments.
- Integrated overload, overtemperature, and overcurrent safety alarms will preserve the performance over time by stopping the stirring
- Safe start and stop knob operation and lock key avoid unintended start up and changes of the working conditions.
- Integrated vibration sensor with different levels of sensitivity will stop the operation and inform to be sure that OHS is stable and properly fixed.
Best-in-class Stirring Power
The OHS 200 Advance is the ideal solution for demanding applications operating with viscosities up to 100.000 mPa. The electronic 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.
SpeedServo torque compensation technology keeps the speed constant automatically adjusting to viscosity changes.
Thanks to the two speed gears it provides the best performance for both high torque and high volume operations:
- Speed gear 1: 6-400 rpm
- Speed gear 2: 30-2000 rpm
Constant torque at any speed
The brushless motor and the microprocessor guarantee excellent performance.
The torque is stable at throughout the whole speed range, ensuring stirring at maximum torque even at the highest speed. This is a very important parameter for the reproducibility of tests.
Precise torque measurement in the dedicated section of the display and can a monitor in the real-time graph the evolution of the torque power during test.
SmartChuck: shaft accommodation has never been so easy
The OHS 200 Advance SmartChuck technology simplifies the shaft accommodation process that can be carried out even with one hand and does not require any tool, making life easier.
With two simple operations, can unlock the protection ring to drive the shaft in and out with maximum ease.
The opening of the ring during the stirring process will automatically block the analysis and the instrument informs for maximum safety.
Intuitive and precise
The OHS 200 Advance intuitive 3,5" TFT Display will guide to precisely set working conditions and get reproducible results. It shows the main information at a glance together with torque measurement on display for real-time information on viscosity change with a resolution of 1 Ncm.
Interact with the OHS 200 Advance from the real-time graph showing speed, torque and temperature of test.
The OHS 200 Advance works unattended thanks to the timer settable from 1min to 99.59h. Define and program operating methods that are ideal for demanding tasks where ramps and interval operation are required.
Keep Temperature Under Control
Constantly monitor the temperature of reaction and set the instrument to reduce speed or interrupt the task if the temperature reaches a defined value. This is important when want to avoid that exothermic reactions will interfere with analysis.
The advantages of OHS 200 Advance connectivity
The OHS 200 Advance is the only overhead stirrers to offer the possibility of controlling and monitoring processes through Wi-Fi connection to VELP Ermes and through USB.
VELP Ermes cloud platform allows to control the OHS 200 Advance from PC, smartphone and tablet through a simple and intuitive web interface. With this platform designed by VELP , it is possible to activate the stirring, set a timer, set a method (among those saved on the device), download and share reports with a click.
For the applications in the pharmaceutical, biotechnology and life science sectors, VELP Ermes can manage OHS 200 Advance located in clean-rooms or other controlled environments, without the need of long safety procedures.
With the OHS/CotrollerSoftTM software, VELP offers the possibility to all laboratories that can't benefit from cloud services, a valid alternative with USB connectivity.
