Product information "Milwaukee PH58 waterproof pH / ORP / Temperature Tester with automatic temperature compensation (ATC) and replaceable probe"

Waterproof meter for the simultaneous measurement of pH, redox potential, and temperature. The Milwaukee PH58 features automatic temperature compensation and a replaceable electrode.

Milwaukee PH58 waterproof pH, redox, and temperature meter with automatic temperature compensation and replaceable electrode

The Milwaukee PH58 is a versatile meter for the simultaneous determination of pH, redox potential (ORP), and temperature. By combining these three key parameters, the device is ideally suited for applications requiring a comprehensive assessment of water quality. Whether in aquaculture, water treatment, environmental analysis, or the laboratory, the PH58 enables reliable and convenient monitoring of various readings using a single device.

A key advantage of the Milwaukee PH58 is its redox measurement capability. In addition to pH and temperature, it measures the oxidation-reduction potential of a solution. This provides users with a more complete picture of water quality, allowing for better monitoring and documentation of critical processes.

To ensure precise results, the device features automatic temperature compensation (ATC). Temperature fluctuations are automatically accounted for during pH measurement, ensuring stable and reliable readings. The integrated temperature sensor also allows for direct monitoring of the sample temperature.

The replaceable electrode ensures a long service life for the meter. Should the electrode wear out or its performance decline, it can be replaced without needing to discard the entire unit. This significantly reduces ongoing costs and simplifies maintenance.

pH calibration is performed automatically via a one- or two-point process using standard buffer solutions. The redox sensor comes factory-calibrated and is ready for immediate use, enabling quick setup and reducing the workload for the user.

The waterproof housing protects the device during work in damp environments, making the PH58 a reliable solution for both mobile and stationary use. Its robust design, ease of use, and versatile measurement capabilities make this model an ideal companion for professional users and demanding measurement tasks.

Frequently Asked Questions Why do I need a buffer or calibration solution? It allows you to set up your measuring device correctly and ensures reliable readings. How often should I calibrate my measuring device? That depends on how often you use it. If used frequently, regular calibration is recommended. Is the Milwaukee calibration solution also suitable for other measuring devices? In many cases, yes, provided the same measurement range is used. Can I use an opened solution more than once? Yes, as long as it remains clean and is stored correctly. How do I store buffer and calibration solutions correctly? It is best to store them in a cool, dry place and keep them tightly sealed. How do I know when I should recalibrate? If the readings seem unusual or change significantly.
