Rod stirrer OHS 40 Digital VELP

OHS are designed to ensure the highest safety standards. The resistant sealed case and the IP 54 degree of protection guarantee durability over time even in the most aggressive environments.
Continuous trouble-free operation in your lab, backed by a 3-year extended warranty.

Constant torque at any speed
The powerful brushless motor and microprocessor control ensure unprecedented performance, highlighting the difference between a conventional shaft stirrer and VELP OHS Series shaft stirrers.
Thanks to the SpeedServo feedback system, the torque remains constant at any speed, even at maximum. Always having a constant torque is a very important parameter for the reproducibility of the analyses.

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 drop into the liquid?
SmartChuck™ technology makes this activity quick and easy with just one hand and no special accessories.
Two simple movements allow you to unlock the protective ring and remove or replace the stirring rod.
If the protection ring is opened during the analysis, the instrument interrupts the stirring, showing a safety message on the display.

Maximum Protection and Security
OHS Advances guarantee the highest safety standards.
The IP54 degree of protection ensures maximum protection of the instrument from corrosion and high performance in challenging work environments.
The stirring is activated through pressure, avoiding involuntary start-ups and the set speed is reached gradually.
The large number of sensors and safety controls deactivate the stirring in case of overload, overheating or short circuit.

Integrated Timer to Schedule Your Activities
The OHS Digitals are equipped with timers that allow you to program the stirrer according to your needs and to carry out the reactions independently.
Setting the timer is quick and easy, just press the dedicated button and select a time interval between 1 min and 99:59 hours.
