Dedicated EC Meter and TDS/Salinity Meter edge® - HI2003
edge®EC—Innovation in a Single Parameter
edge EC’s groundbreaking design is the culmination of Hanna’s vision, design capabilities, integrated production and world class R&D. edge EC is a single meter that can measure EC, TDS, and salinity.
Additional feature information • Digital four-ring conductivity probe Covers all ranges from 0.00 μS/ cm to 500 mS/cm (absolute EC) • Accuracy ± 1% of the reading (±0.05 μS/cm or 1 digit, whichever is greater) • Calibration Offset (0 µS/cm) and cell factor calibration Choice of 5 standards (auto-recognition) • Data logging Manual log-on-demand Manual log-on-stability Interval logging • GLP data Records date, time, offset and cell factor. Data of the last performed calibration is stored in the probe: date, time, cell constant, temperature coefficient, reference temperature and battery status. When the probe is connected to edge®EC, GLP data is automatically transferred • Auto-ranging or manual range selection • EC, TDS and salinity reading modes • Temperature compensation Automatic NoTC (absolute) • Adjustable EC to TDS conversion factor • Adjustable temperature correction coefficient • Seawater salinity units % NaCl PSU g/L
edge®EC technical features
Rechargeable Battery edge EC has a built in rechargeable battery that is charged when the meter is in the plugged in benchtop or wall mount cradle. The battery can also be recharged through the micro USB port with either a USB port from a computer or directly to the power supply
Two USB ports
edge EC includes one standard USB for exporting data to a flash drive. edge EC also includes one micro USB port for exporting files to your computer as well as for charging when the cradle is not available.
Clear, full text readout
edge features clear, full text guides displayed on the bottom of the screen. There is no need to decipher scrambled abbreviations or symbols; these helpful messages guide you through every process quickly and easily.
Sleek design
Incredibly thin and lightweight, edge measures just 1/2” (12 mm) thick and weighs just 8.8 ounces (250 g).
Data logging
edge EC allows you to store up to 1000 log records of data. Logging data sets include readings, GLP data, date and time.
GLP
Data of the last calibration you perform is stored in the sensor including the date, time, and buffers used. When the sensor is connected to edge EC, GLP data is automatically transferred.
Two Operating Modes
Extended Mode enables
all edge features while
Basic Mode reduces
features—ideal for routine measurements by displaying a simplified screen and features.
Capacitive touch keypad
edge EC features sensitive capacitive touch buttons for accurate keystrokes when navigating edge’s menus and screens. Since they are part of the screen, the buttons can never get clogged with sample residue.
Easy to read LCD
edge EC 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 150° viewing angle, provides one of the easiest to read LCDs in the industry
Zero footprint
Using the wall mount cradle (included), edge EC can be placed on a wall, leaving zero footprint on the benchtop space. The cradle has a built-in connector to power and charge the batteries
3.5 mm probe input
Plugging an electrode in has never been simpler; no alignments or broken pins, simply connect the 3.5 mm plug and begin. Digital electrodes are automatically recognized.
A hybrid meter that can be used in portable, wall-mount and benchtop configurations
The versatile design of edge®EC enables it to be used as a portable, wall-mount or benchtop meter. edge EC simplifies measurement, configuration, calibration, diagnostics, logging and transferring data directly to a computer or USB drive.
Portable field unit
edge EC is ideal for field use due to its light weight, large screen, and thin design. It can easily be slipped into a backpack or messenger bag. The battery life lasts up to 8 hours when used as a portable device.
Wall–mount cradle
The included wall–mount cradle makes it easy to conserve space on the benchtop while also charging edge EC with the AC adapter. The cradle is ideal for continuous monitoring applications. 
Digital electrodes
edge®EC performs measurements through its unique digital electrodes. These digital electrodes are auto-recognized, providing sensor type, calibration data and a serial number when connected to edge EC by an easy to plug-in 3.5 mm connector.
Electrode holder with built-in cradle
The electrode holder features a swivel, adjustable arm with a built-in cradle to hold edge EC securely in place at the optimum viewing angle.
