Replaceable graphite electrode An easy-to-replace graphite electrode with a sturdy, snap-in connector means there are no pins to bend or break. Exposed temperature sensor An exposed temperature sensor allows for rapid automatic temperature compensated measurements. Instability & ATC indicators Ensures reliable EC and TDS measurements. ATC symbol is shown when active. Adjustable temperature coe°cient factor Users can choose between dierent factors (ȕ) for precise temperature compensated measurements. HOLD function The HOLD function “freezes” the LCD display temporarily. On-screen battery life LCD indicates the percentage of battery power remaining upon startup. Adjustable TDS conversion factor For measurement accuracy, users can choose between a range of conductivity to TDS conversion factors.
