PINPOINT ORP/REDOX Controller is an inexpensive yet rugged ORP controller interface device. This device will function as a full time visual ORP monitor and can also automate up to 2 additional electrical devices via the electrical plug inputs on the back of the controller. The device(s) attached via electrical plug to the controller must have a methodology to raise or lower the ORP value. One device could be a mechanism to raise the ORP measurement such as an Ozone Generator or ORP increasing solution like potassium permanganate or chlorine to raise the ORP measurement. Another electrical device to lower the ORP measurement can be added as well, if desired. The user would program an ORP value to energize the attached device to lower or raise the ORP to a preselected value at which time the controller will stop electricity. The user may attach one or both devices depending if ORP control is desired in only one direction or both up and down directions. The user will select an optimal ORP value and a range of acceptable ORP around this value. This full-featured controller will accommodate an electrical device up to 5 amps/50-60Hz at 210-240 VAC. Comes complete with PINPOINT ORP electrode with Ultrapure Platinum tip with 10 foot cable, Pre-mixed High Precision +400mV Calibration Fluid, Probe Storage Bottleand Adjusting Screwdriver.
