Portable multiple parameter water, to measure water quality

Model Number: 335 Portable Multi-parameter Water Key Specifications/Special Features: 90P series multiple parameter meters are capable of measuring up to 9 water quality parameters, including pH, mV, ORP, Ion concentration, conductivity, TDS, salinity, resistivity, dissolved oxygenMeter contains a system menu that allows you set many default parameters to meet your personal preference or GLP standardsMeasurement modes for each model:900P: pH, mV, ORP, Ion, conductivity, TDS, salinity, resistivity, D0, C/F901 P: pH, mV, conductivity, TDS, C/F902P: pH, mV, ORP, conductivity, TDS, salinity, resistivlty, C/F903P: pH, mV, ORP, DO, C/F

900P: conductivity, TDS, salinity, resistivity, D0, C/F

Features:

pH mode:

• Up to 5 points push button calibration with auto-buffer recognition
• Selectable pH buffer standards (USA, DIN, NIST, User-defined), resolution (0.1, 0.01, 0.001 pH) and temperature units (C or F)
• Automatically calculates and displays electrode slope that helps you decide whether to replace pH electrode
• Calibration due reminder prompts you to calibrate the meter regularly

ORP mode:

• Absolute or relative mV measurements provides accurate ORP measured value
• 1 point offset calibration allows you adjust displayed value to a known standard

Ion mode:

• Standard BNC connector can connects any combination ion selective electrode
• 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
• mV measurement made allows user to check performance of ion electrode
• Calibration due reminder prompts you to calibrate the meter regularly
