The pH ORP sensor is the wear item on an Ultrameter or TechPro II swapping it restores original accuracy at a fraction of instrument cost, and the job is done in the shop rather than at the factory. Application Replace the sensor when calibration no longer holds, response slows noticeably, or readings drift between buffers. In hot, high solids or chemically
