Introduction
The HI6221 is a streamlined desktop instrument with a large touch screen display, consisting of an instrument housing and an integrated pH/ORP measurement module. The benchtop meter is compact and easy to operate and features a Hanna Instruments HI1131B dual-junction combination pH electrode and HI7662-TW temperature probe.
The HI1131B is a glass body, double junction, refillable pH electrode with an indicator sensor made of high temperature (HT) glass. The dual junction reference and HT glass design allows the HI1131B to be used in a variety of applications, including samples with metals and high temperatures. The connection of the electrodes to the device is secured via galvanically isolated BNC connections. The HI7662-TW stainless steel temperature probe allows the meter to perform automatic temperature compensated (ATC) pH measurements.
HI6221 is equipped with an electrode holder with flexible arms. The holder installs quickly and provides secure support for the electrode when measurements are taken in the sample container.
