Safety and resistance for your laboratory

OHS 200 Digital is designed to guarantee the highest safety standards. The durable watertight housing and IP 54 degree of protection ensure durability even in the most aggressive environments.

Built-in safety alarms for overload, overtemperature and overcurrent will preserve performance over time and stop fidgeting for maximum safety in your lab.
The safe operation of the start and stop knobs and the lock key prevent unintentional ignition and changes in working conditions.

OHS 200 Digital guarantees continuous operation and is backed by a 3-year warranty extension.

Intuitive Interface for Easy Use

The OHS Digital are equipped with a digital display for easy reading of the speed and a 4-segment LED display for torque monitoring, informing you about viscosity variations, guaranteeing any type of analysis, even the most challenging.
It is possible to lock the instrument through the Lock function, preventing inadvertent changes to the settings, and set the timer through the dedicated button for unattended operations, from 1min to 99.59h.
The USB interface facilitates software updates as needed.




Constant Torque at Any Speed

The powerful brushless motor and microprocessor control ensure unprecedented performance, highlighting the difference between a conventional rod stirrer and VELP OHS Series rod stirrers.
The torque remains constant at any speed, even at maximum. Having a constant torque is a very important parameter for the reproducibility of the analyzes.

OHS 200, thanks to its two-speed gears, provides the best performance for both high-torque and high-volume operations:

Gear speed 1: 6-400 rpm
Gear speed 2: 30-2000 rpm

SmartChuck Technology: Inserting or Removing an Auction Has Never Been So Simple!

How often do you have to remove or replace the stirring rod using two hands and see the rod fall into the liquid?
SmartChuck ™ technology makes this activity quick and easy with the use of one hand and without special accessories.
Two simple movements allow you to unlock the protection ring and remove or replace the stirring rod.
In the event that the protection ring is opened during the analysis, the instrument stops shaking, showing a safety message on the display.
