Advanced pH/ORP Benchtop Meter - HI6221
HI6221 is a streamlined benchtop meter with a large touchscreen display, comprised of a housing and an integrated pH / ORP measurement module.
Compact and easy to operate, the benchtop meter is delivered with Hanna Instruments HI1131B double junction combination pH electrode, together with HI7662-TW temperature probe.
This system responds to a complex range of measurement and monitoring requirements, providing accuracy, reproducibility, and reliability.
HI6221 is supplied with an electrode holder that has a flexible arm. The holder can be mounted quickly and provides secure support for electrodes while taking measurements in sample containers.
User interface
- 7-inch capacitive touch screen with multi-touch support
