PHscan30F pocket pH tester is equipped with flat surface pH electrode that used to measures pH of semisolid substances, e.g., fruits, bread, creams, etc.     Features:   Up to 3 points push-button calibration with auto-buffer recognition.   Selectable pH buffer standards and temperature units.   Manual temperature calibration.   Automatic Temperature Compensation provides accurate readings       over the entire pH range.   Hold function freezes the current displayed value for easy viewing.   Auto-power off feature helps you effectively conserve battery life.   Setup menu lets user customizes pH buffer standards, calibration       points, hold function to meet your personal preferences.   Reset feature allows user to resume all of the default settings.   Replaceable electrode module reduces maintenance & replacement       cost.   Waterproof feature to ensures complete protection in harsh       environments.      

Bante320 is a multi-parameter ion meter used for measuring the ion concentration and pH value of liquids. The meter is equipped with a BNC connecter that can connects various combination Ion Selective Electrodes.   Features: During the pH mode, Up to 5 points push-button calibration with auto-     buffer recognition. Selectable pH buffer standards and temperature units. Automatically calculates and displays electrode slope after calibration. During ORP mode, Single point offset calibration allows user adjusts     displayed value to a known standard. Absolute or Relative millivolt (R.mV) measurement provides accurate     ORP readings. During the ion mode, 2 to 5 points push-button calibration from low to     high concentrations. Selectable multiple concentration units, including ppm, mg/L and mol/L. Direct readout ion concentration simplifies the elaborate measurement     process.
