Milwaukee pH Probe

The Milwaukee pH Probe is a high-quality pH probe that is filled with gel and designed for use with select monitors and controllers. The probe features a double-junction design that reduces the risk of clogging, and a spherical glass tip that provides the largest possible surface area for faster and more accurate results. The resin body is tough and can withstand accidental knocks, while also protecting the glass sensing bulb. Additionally, the probe comes with a 6.6-foot cable that provides increased flexibility when measuring. Specifications: Body: Polypropylene Resin Reference: Double, Ag/AgCl Junction: Cloth, Single Electrolyte: Gel pH Range: 0-14 pH Tip Shape: Sphere Diameter: 0.5 inches Dimensions: 4.7 inches / 6.4 inches Operating Temperature: -5 to 70°C (23 to 158°F) Cable length: 6.6 feet Connection: BNC Use and Care The pH meters typically start performing poorly because of problems with the probe. The glass sensing bulb and the reference junction are two parts of the pH probe that cause problems. Sensing Bulb - The sensitivity of the glass bulb in pH probes decreases with use and will eventually lead to failure. Reference Junction - The reference junction is a tiny aperture that enables the pH meter to compare the sample with a reference. The reading is produced by evaluating the electrical disparity between the sample and the reference. If the junction hole is obstructed, the pH probe will cease functioning. To prolong the life of your pH electrode, you can follow the tips below. Storage It is essential to keep the pH probe hydrated to maintain its sensitivity. If the probe is stored in a dry environment for a long time, it can damage its sensitivity and clog the junction hole. To avoid this, it is recommended to store the probe in pH probe storage solution or pH calibration buffers. Do not store the probe in tap or DI water, as it can damage its sensitivity. The best way to store the probe is to fill the probe's cap with storage solution or calibration buffer and tighten the cap to prevent leakage. It is also recommended to store the electrode upright to reduce the potential for leakage further. Cleaning Regularly soaking your electrode in a cleaning solution can prevent residue buildup and blockage of the junction, especially when dealing with samples containing organic material. Calibration The sensitivity of pH-sensing bulbs decreases over time. Therefore, it is essential to calibrate your PRO pH meter regularly. Additionally, calibrate it after cleaning or storing it for an extended period.
