Cole-Parmer’s digital pH tester range is well known for its quality and high standards of performance. With the WZ-59541-00 Waterproof ISFET pH Tester, the company has brought these same standards to a waterproof pH testing instrument. Using a silicon chip pH sensor, this Ion Specific Field Effect Transistor (ISFET) device provides quick, accurate measurement of samples which can be as small as a single drop.

The Cole-Parmer Waterproof ISFET digital pH Tester is a portable, convenient device which is durably constructed – the sensor itself is nearly unbreakable, unlike glass pH sensors, which break easily if the instrument is dropped.

Features of the Cole-Parmer WZ-59541-00 Waterproof ISFET Digital pH tester include:

• pH measurement range 2 – 12

• Resolution of .1 pH

• Accuracy of .1 pH

• 1 point calibration

• Operating temperature range 5 to 40°C (41 to 104°F)
