Multi-parameter liquid analyzer: pH, conductivity, ORP
APT4000PH/APT2000PH Honeywell Process Solutions

The Honeywell Analytical Process Analyzer (APT) 4000 Series offers the widest available selection of advanced features in a reliable and economical instrument. The advanced features of the APT4000 analyzer guarantee complete reliability. The APT4000 continuously monitors sensor and analyzer electronics and immediately displays diagnostic information at the onset of a problem. If an error is found, the analyzer will indicate the appropriate error code or pictograph, blink a red LED and adjust the error current to 22 mA if desired. A manual loop-back check is available to test the integrity of the 4-20 mA output.

APT4000 has a large front display for quick recognition of process parameters and diagnostics even at a distance. Only the APT4000 employs visual feedback to quicken setup and maintenance times and to minimize errors made during calibrations. Visual feedback refers to pictograph type characters that appear on the display both to prompt and respond to operator and process changes. Pictograph type characters also appear during problem conditions to report diagnostics for easy troubleshooting. The Sensoface pictograph provides constant feedback to the operator on whether or not there is a problem with the cell. These easily learned and recognized symbols make the APT4000 an easy-to-use instrument in any language.
