edge® Conductivity/TDS/Salinity is packed with many cutting-edge features to ensure accuracy and usability.
Digital EC Electrode
edge® EC electrode is highly advanced, featuring a built-in microchip that stores calibration information that is automatically retrieved by edge® once the electrode is plugged in. Information stored in the electrode includes model number, serial number and calibration information including the standards used and the date and time the last calibration was performed.
Four Ring Probe
The edge® EC/TDS/Salinity meter is supplied with the HI763100 four ring platinum conductivity probe that has a built-in temperature sensor for automatic temperature compensated measurements. The four ring technology allows for a wide range of measurement with a single probe as compared to amperometric two pole probes that have a limited range and can suffer from polarization effects. The HI763100 probe has a glass and PVDF body with a PEI (polyetherimide) sleeve. Both materials have excellent resistance against many aggressive chemicals.
3.5 mm Probe Input
Plugging an electrode in has never been simpler; no alignments, no broken pins, just connect the 3.5 mm plug and get started.
edge® is incredibly versatile. It can be used in a variety of ways and in a variety of environments without taking up the space of a traditional benchtop meter.
Using the wall mount cradle (included), edge can be placed on a wall, leaving zero footprint on the benchtop space. The cradle has a built in connector to power edge and charge its batteries. edge's zero footprint design saves you valuable benchtop space.
Cradle and Electrode Holder
edge® is equipped with a benchtop cradle featuring an adjustable swivel electrode holder to charge and hold the meter securely in place at the optimum viewing angle.
edge® is incredibly thin and weighs only 8.8 oz., has an 8-hour battery life, and dual USB inputs.
Two USB Ports
edge® includes one standard USB for exporting data with a flash drive and a second micro-USB port for you to connect to a computer for file export and for charging your edge when the cradle is not available.
edge® allows you to store up to 1000 log records of data. Data sets include readings, GLP data, date and time.
Two Operating Modes
edge® offers both Basic and Standard Modes. In Basic Mode, the edge as an EC meter reduces features to simplify operation. In Basic Mode, the meter will only allow for automatic temperature compensation, auto ranging of readings, and automatic cell factor correction while calibrating. The temperature correction coefficient is fixed to 1.9% / °C and interval logging is not available. In Standard Mode, the user has options to change these settings.
