Product code: HI-6221-02
The HI-6221 Advanced Benchtop Meter for pH and ORP is a laboratory-grade solution for accurately measuring key parameters in a wide range of samples. This laboratory pH meter includes WiFi and ethernet connectivity, on-screen tutorials and five different viewing modes during measurement for flexibility and efficiency in testing pH and ORP.
The HI-6221 pH and ORP Meter from Hanna Instruments is a modern, efficient solution for benchtop measurements within laboratories. This sleek, practical laboratory-grade meter includes multiple time-saving features, including on-screen tutorials, practical data transfer over WiFi and ethernet and a user-friendly interface for ease of use.
This research-grade pH and ORP meter is supplied with the Hanna HI-1131B double junction combination pH electrode, a glass-bodied refillable pH electrode that is made from high-temperature glass to provide accurate, reliable pH measurement across a wide range of samples, including metals and samples that have elevated temperatures.
The HI-7662-TW temperature probe is also supplied with the HI-6221 ORP and pH meter, allowing for the automatic compensation of pH measurements for exceptional accuracy and repeatability.
