Features at a Glance Clear, full text readout These meters present clear, detailed text prompts at the bottom section of the screen. Two Operating Modes (HI2621) HI2621 can be used in Standard or Basic operating modes. Standard Mode enables all features while Basic Mode reduces features—ideal for routine measurements by displaying a simplied screen and features. HI2620 operates in Basic Mode only. Data Logging (HI2621 only) The HI2621 provides data storage capacity 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 the date, time, and buers utilized. This information is available in basic and standard modes. For HI2621, this information is also included with logged data. CAL Check™ Hanna’s exclusive CAL Check feature analyzes the pH electrode’s response in calibration buers to detect potential issues such as contaminated solutions or dirty electrodes. Upon completing calibration, indicators re±ecting the probe’s condition—based on its oset and slope characteristics—are displayed on the measurement screen. Sensor Check™ (using HI11311 and HI12301 pH probes only) When paired with compatible Hanna electrodes featuring a matching pin, these meters continuously monitor 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 Both the HI2620 and HI2621 feature 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. 5.5" Easy to Read LCD HI2620 and HI2621 feature a 5.5” (14 cm) LCD display that you can clearly view from over 5 m (16.4’). The large display, with its wide 150° viewing angle, provides one of the easiest to read LCDs in the industry. Small Footprint With dimensions of just 205 x 160 x 77 mm (8.0 x 6.2 x 3.0”) and a weight of only 850 g (1.87 lbs.), these meters oer exceptional portability and seamlessly integrates into the most crowded laboratory workspaces. 2 pH 2.21 www.hannainst.com | benchtop
