Accurate and easy to use, the HI9810462 HALO2 Wireless Refillable pH Tester is ideal for laboratory pH measurements in samples that would be a challenge for standard design pH electrodes. This HALO2 can be used as a stand-alone pH tester or can be connected to a smart device with the Hanna Lab App. The Hanna Lab App turns the device into a full-featured pH meter that features live-readings, data sharing, manual temperature compensation, calibration reminder, pH (mV) and temperature alarms. The Hanna Lab App also features Hanna Cloud compatibility.
The HI9810462 features a non-porous, glass body that is easy to clean and withstands harsh chemicals. The double junction reference design presents a silver-free electrolyte solution interacting with the sample, making the electrode less susceptible to clogging and guaranteeing a fast response and stable reading.
The triple ceramic inner junction allows a higher flow rate of electrolyte from the reference cell into the measurement sample. A typical pH electrode will have a single ceramic junction that provides a flow rate of 15 to 20 μL/hour. The HI9810462 has three ceramic junctions in contact with the sample providing for a flow rate of 40 to 50 μL/hour. The increased flow provides a greater continuity between the reference electrode and the indicating electrode, making it suitable for non-homogenous solutions and samples with highly alkaline pH values. Built-in temperature sensor at the tip of the pH electrode allows for rapid determination of the sample temperature and a high-accuracy temperature reading.
