Measurement Parameters

• BEP-M120: pH, mV, relative mV, temperature

• BEP-M130: pH, mV, relative mV, ion concentration, water hardness, temperature

• BEP-M131: Ion concentration, water hardness, mV, temperature

Features

pH

• 1 to 5 points calibration with automatic recognition for USA, NIST and DIN buffers

• Automatic electrode diagnosis shows the pH slope and offset

• Solution temperature coefficient compensates for the pure water samples and references the pH to 25°C

ORP

• 1 point offset calibration allows adjusting the displayed value to a known standard

• Relative and absolute millivolt modes ensure the reliable ORP measurements

 

Ion Concentration

• 2 to 5 points calibration, including the 8 concentration points can be selected

• Electrode management is capable of storing and recalling up to 3 electrode slopes

• Automatic electrode diagnosis shows the calibration points and slopes

• Selectable ion measurement methods (direct reading, known addition, known subtraction, sample addition, sample subtraction) and concentration units (ppm, mg/L, mol/L or mol/L) Water Hardness

• 2 to 5 points calibration from low to high concentrations

• Selectable measurement units(German degree, English degree,French degree,mmol/L and mg/L) are used for professional water hardness measurements

General Features

• Auto-Read function senses and locks the measurement endpoint.
• Timed Interval Readings sends the measurement data to a PC or printer.
• Limit Alarm automatically alerts when reading exceeds the specified range.
• Calibration due alarm prompts user to calibrate the meter regularly.
• Calibration report shows the date, time, pH slope and offset.
• Password protection prevents the unauthorized calibration and settings.
• Expanded memory stores or recalls up to 1000 data sets.
• Reset function automatically resumes all settings back to the factory defaults.
