Specifically designed for wastewater process control applications to determine solids concentration in percent volume. Measures sludge concentration in 15 minutes. Powered by a 1/8 HP motor, the trunnion head spins 6 test tubes 3000 fixed RPM at a full right angle to the axis of rotation, giving a straight line reading on the tubes. A 15 minute timer provides a reliable spin test for solids concentration. An on/off switch overrides the timer for shut-off anytime during operation. Stainless steel and aluminum construction. Includes 6 polycarbonate 19mm tubes clearly marked for solids concentration in % volume, reading to 50%. Eliminates the need for expensive shields and cushions. 110V
