  ULTRAPEN PT3 ORP/REDOX and Temperature Pen. Save 10% NOW - Now In Stock. Advanced features include highly stable microprocessor-based circuitry; automatic temperature compensation from 15�_C to 30�_C while in calibration mode; user-intuitive design; and waterproof housing. A true one-handed instrument, the PT3 is easy to calibrate and easy to use. To take a measurement, you simply push a button then dip the PT3 in solution. Results display in seconds.This instrument is designed to be extremely accurate, fast and simple to use in diverse water quality applications.Standard Solutions for calibration:The ULTRAPEN_�� PT3 requires Myron L® Company 80mV Quinhydrone, 260mV Quinhydrone, or 470mV MLC Light_��s ORP Calibration Solution for wet calibration and Sensor Storage Solution for proper storage.Replacement ORP Sensor: The ULTRAPEN_�� PT3 features a user replaceable ORP sensor. Installation instructions included with sensor.Order model#: RPT3 ORP Electrode Cleaning Paper: Routinely cleaning the electrode will keep the sensor free of build-up that can affect the speed and accuracy of ORP readings. Instructions for use are included with the paper.Order model#s: OECP-25 for QTY 25 or OECP-100 for QTY 100

To remove, twist soaker cap while pulling off. To replace, fill soaker cap with storage solution just until sponge is covered. Squeeze and release tip of soaker cap so sponge will saturate with solution, then pour out any excess solution. Twist soaker cap while pushing back on. CAUTION: Do NOT overfill the soaker cap as solution can squirt out while you are pushing the cap back onScoop _�� used to hold sample solution when dipping is not possible. To install, push scoop onto sensor while shifting side-to-side. To remove, pull scoop off while shifting side-to-side. Verify ORP sensor remained fully inserted into PT3.

If this occurs, the PT3 will turn off.* Temperature compensation in calibration mode: Temperature affects the reaction potentials for all chemicals differently. True ORP is the direct measurement of electron activity during an oxidation-reduction reaction, regardless of temperature. However, for maximum accuracy and ease of calibration, the Myron L® Company has developed three calibration solutions with known dissolved species. We derived the temperature compensation (from 15�_C to 30�_C) for those solutions, and embedded automatic temperature compensation into the calibration function of your PT3. Note: To verify calibration while in measurement mode, you must manually correct for any variation in temperature. Example: @25�_C, ORP2602OZ calibration solution will read 260mV, however @ 20.0�_C ORP2602OZ will read 265mV.
