Extech EC500 ExStik II Waterproof pH/Conductivity Meter

A 5-in-1 testing device, Extech's EC500 is capable of carrying out measurements of conductivity, TDS, salinity, pH and temperature.

The EC500 uses a rugged, high quality flat surface electrode in order to carry out comprehensive measurements. It can measure conductivity from 0 to 199μS/cm, 200 to 1999μS/cm, 2.00 to 19.99mS/cm, TDS/salinity from 0 to 99.9ppm (mg/L), 100-999ppm (mg/L), 1.00 to 9.99ppt, pH from 0.00 to 14.00pH and temperature from 23° to 194°F (-5 to 90°C). 9 measurement units are also included on the device, with pH, μS/cm, mS/cm, ppm, ppt, mg/L, g/L, °C and °F all available.

This product also features a large size LCD screen which relays the current testing result. This screen always shows a temperature value against a measurement of conductivity/pH or whatever is selected, along with bargraph representation for spotting trends in measurements. The unit includes 25 record memory as well, allowing users to easily store a testing record and recall it later for quick reference.

The EX500 is IP57 waterproof.
