Extech Instruments – EC500 ExStik II
Waterproof pH/Conductivity Meter
Extech is a manufacturer if high quality electronic testing and monitoring
instruments.
ExStik II waterproof combination pH, Conductivity, Total Dissolved Solids (TDS),
Temperature (°C or °F) and Salinity meter. It is the Swiss Army Knife of water
property meters.
Key Benefits
A reliable combination pH/Conductivity meter that is pocket-sized. In addition
to monitoring the pH and Conductivity, the TDS function can be used to check
incoming water supplies for degree of hardness and the Thermometer can be used
for checking the temperature on fountain solution, developer, fixer or any other
critical liquid in the print shop. The auto ranging capability in the
Conductivity mode eliminates the need to predetermine the correct range for the
sample being tested – the meter does it for you!
Features:
 | Nine units of measure – pH, µS, mS, ppm, ppt, mg/L, °C and °F |
| Analog bar graph indicates trends |
| Internal memory stores up to 25 labeled readings for easy recall |
| Adjustable Conductivity to TDS ratio from 0.4 to 1.0 |
| 0.5 fixed Salinity ratio |
| CAL feature warns to check calibration, but allows continued use |
| RENEW feature alerts user when electrode needs replacement |
| Data Hold, Auto Power Off and Low Battery indicators |
| Waterproof to IP67 Standard |
| Complete with flat surface electrode (minimizes fouling for increased
accuracy), sample cup
with cap, polishing paper, four 1.5V SR44W batteries and 48” neck strap
