The Oakton WD-56717-37 pH 550 monitor with NIST calibration is used to measure pH/ORP and temperature values in applications such as water treatment and monitoring, chemical processing, or food processing. The monitors have user-friendly features like menu-driven programs and calibrations that are easily performed with the push-button keypad. All setup and calibration parameters are retained in the non-volatile memory to prevent data loss during power outages.
Measurements are compensated for temperature variations automatically when used with pH electrodes that have temperature elements. The WD5671737 also offers manual temperature compensation with independent settings for calibration and process temperature. One- or two-point calibrations can be performed with USA or NIST buffer sets. All values, operational, and error messages are indicated on the large, dual-line LCD. All setup and calibration parameters are retained in the nonvolatile memory to prevent data loss during power outages.
