Product Description

The HST30 series stir tester is available in direct-drive or geared models with a totally enclosed, reversible, 1/4 hp, permanent-magnet DC motor. This stir tester is available in both 120V and 240V versions. The digital readout displays speed in rpm's and torque in lb-in (kg-cm for geared motors). The front panel switch toggles between speed and torque.

Features include:

  • 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 switchable 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.

This system is furnished complete with a reversible drive motor and mounting bracket, controller, and the following accessories:

Stand sold separately (stir tester is shown here with the recommended item# 21058 stand). The controller lab bench case measures 8" w x 8" d x 4.75" h. The motor bracket is 5.0" x 5.5" d x 10" h with an 8.5" rod. Foxtip gray and charcoal finish.  Product weight: 20 lb (9.07 kg) for the direct drive and 24 lb (10.89 kg) for the geared models.
