HI-2631 benchtop meter enables fast, accurate measurements utilising the Hanna Instruments digital electrode for conductivity (HI-763100) which includes an integral temperature sensor. Each digital electrode has a unique serial number and the parameter that it measures is automatically identified by the meter.
The 2631 measures conductivity and TDS while adding salinity measurement and calibration along with data logging capabilities.
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. Additionally, the HI-2631 can be used in Standard Operating Mode, where all features and capabilities are enabled.
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-2631 presents clear, detailed text prompts at the bottom section of the screen.
Two operating modes - HI-2631 can be used in Standard or Basic Operating Modes. Standard Mode enables all features while Basic Mode displays a simplified screen and features which is ideal for routine measurements.
Data logging - The HI-2631 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-2631, this GLP information is automatically transferred.
Capacitive touch keypad - HI-2631 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-2631 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.
USB-C port for charging and data transfer - The HI-2631 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.
