The PT4 Agitator overcomes these problems. The device is designed so that a soft
bristle brush sweeps across the probe membrane or sensor tip. This sweeping
action of the brush provides the required water velocity as well as prevents the
membrane from becoming bio-fouled.
The optimum sweeping frequency depends upon the design of probe and type of
membrane used and water conditions. An ON-time of 0.25 seconds and OFF-time
of 5 seconds is suitable in most circumstances.
Agitator’s overall size: 7-1/8" x 3-1/4" diameter, 1-1/4 lb. (180mm x 83mm, 0.6 kg)
Supplied with 10 ft. (3 meters) cable.
Power required: 10.5 to 18 VDC at the agitator, 1.1 amps. Maximum ON-time is
3 seconds.
