Features & Applications:

This Hanna portable low range EC / TDS tester is designed for quick and easy use with high accuracy EC, TDS and temperature measurements. This waterproof instrument features a dual-level LCD that displays EC or TDS and temperature in °C or °F, simultaneously. This microprocessor-based meter has been developed in direct response to users' requests in water treatment, boilers and cooling towers, reverse osmosis and agricultural applications. Rugged and easy-to-use the DiST® 7 features an on-board sample cell with built-in funnel, digital readout, push button automatic calibration and automatic temperature compensations. The EC/TDS conversion factor and temperature coefficient (ß) are user-adjustable for application-specific measurements. At startup the DiST® 7 performs a self-check and then displays the battery level to assure proper working conditions. Each unit has a stability indicator and hold feature to prompt the user when to freeze the display and take a reading for easy and accurate recording.
