The ExStik® Series for Wastewater Testing

Waltham, MA - Perform 7 essential wastewater tests (Chlorine, pH, ORP, Conductivity, Total Dissolved Solids (TDS), Salinity and Temperature) with just two ExStik® meters.

The ExStik® CL200 meter quickly and easily tests for Total Residual Chlorine, pH, and ORP in liquids, semisolids, and solids. The meter also measures temperature from 23° to 194°F (-5° to 90°C). As Model CL200, the ExStik® measures from 0.01 to 10.00ppm total chlorine using an EPA approved method. The measurement is unaffected by sample color or turbidity. A built-in memory stores 15 sequentially tagged data points. With a quick change of electrodes the meter converts to the Model PH100 and accepts either gel-filled or liquid refillable pH electrodes to measure pH. "RENEW" indicates the need for electrode replacement and "CAL" reminds the user to recalibrate. Another quick electrode change converts the meter to Model RE300 and provides automatic self-calibration for ORP.

The NEW EC400 is the second in the ExStik® series. It measures Conductivity, TDS, and Salinity and allows the user to choose the measurement by simply pushing a button to select the conversion factor. Measurement units include µS, mS, ppm, ppt, mgL, and g/L. Like its sister meter, the EC400 measures temperature is waterproof, and can store up to 15 data points.
