The DiST®7 portable meter from HANNA instruments® is designed for quick and easy, high accuracy EC, TDS and temperature measurements. This new waterproof instrument features a dual-level LCD that displays EC or TDS and °C or °F. This microprocessor meter has been developed in direct response to the requests of users in water treatment, boilers and cooling towers, reverse osmosis and agriculture. The rugged, easy-to-use DiST®7 features an on board sample cell with built-in funnel, digital read out, push button automatic calibration and automatic temperature compensation. 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 condition. It also has a stability indicator and hold feature to prompt the user when to take the reading and freeze the display for easy and accurate recording. |
DiST®7 is supplied complete with calibration solution, batteries and instructions. |
