Hanna Instruments HI-98311 DiST Pocket EC/TDS/Temperature Tester — Low Range

The Hanna Instruments HI-98311 is a floating, waterproof pocket tester for low range conductivity (EC) and total dissolved solids (TDS) measurement, designed for clean water and tap water applications. Part of the Hanna DiST range, the HI-98311 combines ease of use with an impressive feature set that makes it unmatched in its class for EC/TDS and temperature measurement at an accessible price. Two button operation, a dual level display for simultaneous readings and a direct contact temperature probe make routine testing fast and straightforward.

The HI-98311 features automatic single point calibration with automatic temperature compensation, a user-selectable TDS conversion factor (0.45 to 1.00) and an adjustable temperature compensation coefficient (0.0 to 2.4%/°C). The replaceable graphite electrode snap-in probe is easy to swap out when required, and the BEPS Battery Error Prevention System alerts the user if low battery power could adversely affect readings. The bright floating waterproof case and removable safety cap complete a well-specified, practical instrument for everyday EC and TDS monitoring.
