HI-2600 pH EC and DO Benchtop Meter

HI-2600 pH EC and DO Benchtop Meter

HI-2600 benchtop meter enables fast, accurate measurements utilising the Hanna Instruments digital electrode / probes for pH (HI-11310), ORP (HI-36180), conductivity (HI-763100), or dissolved oxygen (HI-764080). 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, measurement, data logging and transfer of data to a USB thumb drive or computer. The benchtop meter offers a Basic Mode that streamlines measurement configuration and is useful for routine applications.

The compact meter (and probe) can be used as a portable device (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.

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-2600 presents clear, detailed text prompts at the bottom section of the screen.

Two operating modes - HI-2600 can be used in Standard or Basic Operating Modes (pH and EC only). Standard Mode enables all features while Basic Mode displays a simplified screen and features —ideal for routine measurements.

Data logging - The HI-2600 provides ample data storage capacity, allowing you to save up to 1000 log records. Each data set comprehensively includes readings, GLP information, as well as date and time stamps.

GLP - The sensor retains data from the most recent calibration, including date, time, and buffers utilised. When connected to the HI-2600, this GLP information is automatically transferred.

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 only) - When paired with compatible Hanna electrodes featuring a matching pin, HI-2600 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-2600 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-2600 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.

Rechargeable battery - The integrated rechargeable battery offers maximum portability with a long 8-hour battery life.

USB-C port for charging and data transfer - The HI-2600 features a streamlined USB-C port that facilitates charging the integrated rechargeable battery, transferring data to your computer, and exporting files directly to a flash drive.
