HI-2620 enables fast, accurate pH and ORP measurements utilising the Hanna Instruments HI-11310 digital pH electrode and HI-36180 digital ORP probe. Each digital electrode / probe has a unique serial number and the parameter that it measures is automatically identified by the meter.
Once connected, the single sensor or sensors are ready to measure the parameter along with temperature.
The intuitive design simplifies configuration, calibration, and measurement.
The compact meter (and probe) can be used as a portable device for out in the field (using its rechargeable battery) or used as laboratory instrumentation.
The meter has a large display with capacitive keys which features a 5.5” (14 cm) LCD. The large display provides a 130 ° wide viewing angle.
Main feature points
- Automatic parameter recognition
- pH/ORP choice of measurement units: pH, mV;
- CAL Check indicators
- Sensor Check indicators
- Simplified operation for routine measurements
- Dedicated GLP key
- Internal clock and date
Digital probe input - simply connect each probe via the 3.5 mm jack, Digital Smart Electrodes are automatically recognised.
Clear, full text readout- The HI-2620 presents clear, detailed text prompts at the bottom section of the screen.
GLP - The sensor retains data from the most recent calibration, including date, time, and buffers utilised.
CAL Check - Hanna’s exclusive CAL Check feature analyses the pH electrode’s response in calibration buffers to detect potential issues such as contaminated solutions or dirty electrodes. Upon completing calibration, indicators reflecting the probe’s condition—based on its offset and slope characteristics—are displayed on the measurement screen.
Sensor Check (using HI-11311 and HI-12301 pH probes) - When paired with compatible Hanna electrodes featuring a matching pin, HI-2620 continuously monitors the impedance of the pH measuring electrode, providing real-time alerts in case of glass breakage. During calibration, Sensor Check displays the junction condition, by evaluating the reference junction resistance.
ORP measurement - Measure ORP (REDOX) in mV units by using a compatible ORP sensor.
Capacitive touch keypad - HI-2620 features sensitive capacitive touch buttons for accurate keystrokes for navigating menus and screens. Since they are part of the screen, the buttons can never get clogged with sample residue.
Easy to read LCD - HI-2620 features a 5.5” (14 cm) LCD display that you can clearly view from over 5 m (16.4’). The large display, with its wide 130° viewing angle, provides one of the easiest to read LCDs in the industry.
