The HI6221 is a sleek benchtop meter featuring a large touchscreen display, combining compact housing with an integrated pH/ORP measurement module. Designed for ease of use, the meter comes with Hanna Instruments HI1131B double junction combination pH electrode and the HI7662-TW temperature probe.
The HI1131B electrode is constructed with a glass body and features a double junction, refillable design, and a high-temperature (HT) glass indicating sensor. This configuration allows the electrode to perform reliably across various applications, including those involving metals and high temperatures. It connects to the meter via a galvanically isolated BNC connection for secure attachment.
The HI7662-TW temperature probe, made of stainless steel, enables automatic temperature compensation (ATC) for pH measurements. This system addresses complex measurement and monitoring needs, ensuring accuracy, reproducibility, and reliability.
