Bante210 standard pH meter is an easy-use benchtop meter designed for daily testing and controls.   Features: Large backlit LCD display shows mode indicators and help messages. Up to 3 points push-button calibration with auto-buffer recognition. Selectable pH buffer standards and temperature units. Automatically calculates and shows electrode slope after calibration. Automatic Temperature Compensationensures highly accurate     measurement over the entire pH range. Automatic endpoint function freezes the stable measured values for     easy reading and recording data. Manual temperature calibration provides accurate temperature value. Help message as a operational guide that can help users quickly use     the meter.   Setup menu lets user customize buffer standard, calibration points,     temperature unit, automatic or manual hold function, auto-off feature     to meet personal preferences. Reset function can resumes all settings tofactory default values. 　

Bante930 is a high accuracy meter used for measuring the ion concentration, ORP and pH values of liquids. The meter widely used in environmental studies, chemical labs, swimming pools, spas to monitor the chemical reaction of water.   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.
