HACH HQ411D Laboratory pH Meter with PHC201 Electrode

The HACH HQ411D pH meter is a benchtop instrument used for measuring pH and ORP (oxidation-reduction potential) in laboratory water analysis, wastewater treatment, and environmental testing. It delivers selectable pH accuracy of 0.001/0.01/0.1 pH with automatic temperature compensation, making it suitable for precise quality control and research applications.

The HACH pH meter MPN 8507560 offers pH accuracy of 0.001/0.01/0.1 pH, automatic temperature compensation, and measures ORP. It includes the HQ411D Laboratory pH Meter, a PHC201 Std Gel Filled pH Electrode with 1 m cable, a universal electrode stand with electrode holder, and 500 mL pH electrode storage solution.

To maintain the HACH PHC201 gel-filled pH electrode, rinse it with deionized water after each use and store it in the supplied pH electrode storage solution (500 mL) to keep the glass bulb hydrated. Avoid letting the electrode dry out. For best accuracy, calibrate regularly with standard buffer solutions and replace the electrode when response becomes sluggish.
