DiST 7 & DiST 8 portable meters from HANNA® are designed for quick and easy use with high accuracy EC, TDS and temperature measurements. These waterproof instruments feature a dual-level LCD that displays EC or TDS and temperature in °C or °F, simultaneously. These microprocessor meters have 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 DiST 7 & DiST 8 each feature 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 DiST 7 & DiST 8 perform a self-check and then display 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.
