The HST20 lets you maintain stirring speed with a 1/8 hp, totally enclosed, permanent-magnet DC motor. Digital readout displays speed in rpm’s and torque in oz-in. Front panel switch toggles between speed and torque. Actual speeds are displayed and maintained by a synthetic tachogenerator. (Speed is kept within less than 1% of the base speed from no-load to more than 100% of full-load regardless of AC line voltage fluctuations of 10%.) Viscosity measurement is easier … Read more

The HST20 lets you maintain stirring speed with a 1/8 hp, totally enclosed, permanent-magnet DC motor. Digital readout displays speed in rpm’s and torque in oz-in. Front panel switch toggles between speed and torque.

Actual speeds are displayed and maintained by a synthetic tachogenerator. (Speed is kept within less than 1% of the base speed from no-load to more than 100% of full-load regardless of AC line voltage fluctuations of 10%.)
Viscosity measurement is easier thanks to a controller with a digital readout switch able between speed and torque.
Data on shear stress, shear rate, velocity gradients, and viscosity is accumulated easily with external DC multi-volt signals for speed and torque (for strip or X-Y recorders) available through an output port on the rear of the control.
Operator convenience and safety is increased with cord connections between drive motors and controls to allow control placement away from hostile environments.

Specifications: The HST20 includes a reversible drive motor with mounting bracket, controller, and the following accessories:

099D A260100 – 3-jaw, keyless chuck and arbor (HST20N & HST220N only)

100D LC300 – heavy-duty 90 clamp
099D A260200 – 3-jaw, keyless chuck and arbor (for HST20 geared motors).
Lab stand 099D A130150 is recommended to mount the HST20.

Lab bench case: 8″w x 8″d x 4.75″h
Motor bracket: 4.5″w x 4.5″d x 9.5″h, with 8.5″ rod
Finish: Foxtip gray and charcoal.

Note: Lab Stand sold separately (see accessories)
