HST30 Series Stir Testers

The HST30 Series Stir Testers deliver precise control for demanding laboratory mixing and testing applications. Equipped with a fully enclosed 1/4 hp permanent-magnet DC motor, these testers maintain stirring speed accurately while providing digital readouts for both speed (rpm) and torque (oz-in). A front panel switch allows easy toggling between speed and torque, simplifying viscosity measurements and process monitoring.

Features:

• Fully enclosed 1/4 hp permanent-magnet DC motor for consistent, reliable operation
• Digital readout displays speed and torque, switchable via front panel control
• Actual speeds maintained within 1% of base speed by a synthetic tachogenerator, even with ±10% AC line fluctuations
• Viscosity measurements simplified with the ability to toggle between speed and torque
• External DC multi-volt outputs provide data for shear stress, shear rate, velocity gradients, and viscosity for strip or X-Y recorders
• Cord-connected drive motors allow remote control placement for improved safety and operator convenience
• Lab bench case: 8.00 in x 8.00 in x 4.75 in
• Motor bracket: 5.00 in x 5.50 in x 10.00 in, with 8.50 in rod
