Integrated applications: - Weighing: determines the weight of the objects on the pan in the selected unit of measurement. - Piece Counting: Counts the number of pieces on the pan using a uniform weight. - Percent Weighing: Measures the weight of a sample displayed as a percentage of a preset weight reference. - Weight check: compares the weight of a sample with respect to the target limits. - Dynamic Weighing: Weighs an unstable sample load. The scale takes an average of weights over a period of time. - Totalization: measures the cumulative weight of multiple objects. The cumulative total can exceed the capacity of the balance. - Density determination: determines the density of solids or liquids. With the integrated weigh below hook, specific gravity tests can be performed for objects that cannot be easily placed on the weighing pan. - Display Hold: Manually holds the last stable weight or the first highest stable weight value on the display. - Mole Weighing: Measures the weight of a sample and  calculate it into Moles automatically

Safety and resistance for your laboratory OHS advance is designed to guarantee the highest safety st (more)andards. - The durable watertight housing and IP 54 protection rating ensure durability even in the most aggressive environments. - Built-in safety alarms for overload, over temperature and over current will maintain performance over time by stopping agitation - The safe operation of the start and stop knob and the lock key prevent unintentional starts and changes in working conditions. - The built-in vibration sensor with different sensitivity levels will stop the operation and inform you to make sure your OHS is stable and properly fixed. Continuous operation guaranteed and supported by a 3 year extended warranty. First-class performance OHS 100 Advance is the ideal solution for demanding applications operating with viscosities up to 70,000 mPa. The electronically controlled brushless motor of the OHS 100 Advance agitates up to 100 l (H2O) with a maximum torque of 100 Ncm and guarantees maximum durability. SpeedServoTM torque compensation technology maintains constant speed by automatically adapting to changes in viscosity. Set the OHS 100 Advance electronic speed control from 30 to 1300 rpm. 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. 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. Intuitive and precise control panel The intuitive 3.5” OHS Advance TFT display will guide you to precisely set your working conditions and achieve reproducible results. Show key information at a glance. Real-time information on viscosity variation with a resolution of 1 Ncm. Interact with OHS Advance from the real-time graph showing speed, torque and temperature of your test. The OHS Advance works without surveillance thanks to the timer that can be set from 1min to 99.59h. Ideal operating methods can be defined and programmed for demanding tasks where ramps and interval operations are required. Temperature under control OHS Advance is supplied with a Pt100 temperature probe included in the package. Constantly monitor the temperature of your reaction and set the meter to slow down or stop activity if the temperature reaches a defined value. This is important when you want to prevent exothermic reactions from interfering with your analysis! THE BENEFITS OF OHS ADVANCE CONNECTIVITY The OHS Advance is the only rod stirrer to offer the ability to control and monitor processes via Wi-Fi connection to VELP Ermes and via USB. The VELP Ermes cloud platform allows you to control the OHS 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 shaking, set a timer, set a method (among those saved on the device), download and share reports with a click. For applications in the pharmaceutical, biotechnology and life science sectors, VELP Ermes can manage OHS Advance localized in clean rooms or other controlled environments, without the need for lengthy safety procedures. With the OHS / CotrollerSoftTM software, VELP offers the possibility to all laboratories that cannot benefit from cloud services, a valid alternative with USB connectivity. The OHS allow you to choose between two different control panels, Digital or Advanced, to better suit the needs of your laboratory. - Digital: precise speed settings; torque indicator; integrated timer. - Advanced: all information at a glance; intuitive; real-time graphs. Very easy to use and comfortable tools. Intuitive control panel equipped with Smartchuck: operations and rod change with one hand, effortlessly. - Mandrel opening: Ø from 1 to 13 mm - Stirring rod diameter for Pass-Through: up to 8.5mm Velp products guarantee you peace and security within your laboratory. - Safety button clearly visible from the front - IP54 protection - Integrated safety sensors CONTROL PANEL OF OHS ADVANCE MODELS A - LCD display B - Display keys C - Stirring speed kond D - Lock key E - Main switch F - Smart Chuck
