Waterproof ExStik® II pH/Conductivity Meter
Combination rugged Flat Surface pH electrode
Innovative design with flat surface technology for quick on-the-spot
pH measurements combined with autoranging high accuracy Conductivity cell
• Measures 5 parameters including Conductivity, TDS,
Salinity, pH, and Temperature using one electrode
• 9 units of measure: pH, μS/cm, mS/cm,
ppm, ppt, mg/L, g/L, °C, °F
• Analog bargraph indicates trends
• Memory stores up to 25 labeled readings
• Adjustable Conductivity to TDS ratio
from 0.4 to 1.0; 0.5 fixed Salinity ratio
• RENEW feature alerts user when
electrode needs replacement
• Auto power off and low battery indicator
• Waterproof to IP57
• EC500 meter includes electrode, protective sensor cap, sample cup
with cap, four 3V CR-2032 batteries, and 48" (1.2m) neckstrap.
Order Conductivity standards and pH buffers separately
• EC510 Kit includes EC500, 84μS/cm, 1413μS/cm,
12880μS/cm Conductivity calibration standards, pH buffer
pouches (1 each of 4, 7, 10pH plus rinse solution), weighted
base, 3 sample cups with caps, and case — $19 Savings
