Compact Magnetic Stirrer HI190M-2

Producer: HANNA Instruments

SKU: HANNA-HI190M-2 Category: Hanna experimental measuring equipment

The HI190M is a compact and lightweight magnetic stirrer. The stirrer is constructed with an ABS plastic casing and is resistant to a wide range of harsh chemicals. Stirring speed is adjustable from 100-1000 RPM. The HI190M magnetic stirrer is an ideal space saver in the laboratory.

Ideally, when performing electrochemical measurements, the samples to be measured should be stirred. The use of a magnetic stirrer allows for proper mixing and the samples are homogenous in consistency and temperature. Sample agitation also speeds up the response time for a sensor to achieve stable measurement values.

Compact & Cost Effective

The HI190M mini-stirrer is compact and lightweight, allowing for easy use in the laboratory environment. Limited space on the laboratory bench is no longer a concern with this durable, space-saving magnetic stirrer. Power-indicating LED lights help users to know at a distance when the stirrer is in operation. The durable plastic casing will resist the harmful effects of accidentally spilled chemicals. The advanced design incorporates electronic controls that allow the user to easily adjust the speed with excellent precision.

Speedsafe™

Often in the laboratory a sample is removed from a stirrer before the speed has been reduced properly, causing the motor to accelerate further and this can cause damage to the internal motor. To control speed from changes in viscosity or when the load is reduced, the HI190M mini-stirrer incorporates the Speedsafe™ mechanism. With Speedsafe, a speed sensing device (optical sensor) is combined with an FVC (frequency voltage converter) to monitor the stirring speed. When the speed reaches a preset maximum level, the speed limiter turns off the VCO (voltage controlled oscillator) to slow the motor speed. This ensures that when the sample is suddenly removed from the stirrer, the motor will not accelerate and there will be no danger to the user or the stirrer; a feature not commonly found in conventional stirrers.
