Use these testers for either cup-style or dip-style measurements. For cup style, pour a small amount of your sample directly into the sensor cup until it overflows; for dip style, simply immerse tester tip into sample.

Replaceable sensor lets you reuse meter body many times over. Valox housing and stainless steel electrodes for good chemical compatibility. Note: Before measuring, calibrate tester as either cup style or dip style (depending on intended method of use).
