HEB900 benchtop multi-parameter water quality meter dissolved oxygen meter
Features of HEB900 multi-parameters water quality meter:
pH Mode: • Multiparameter water quality meter is equipped with a large backlit LCD display. • 1 to 5 points push-button calibration with auto-buffer recognition. • Selectable pH buffer group (USA/NIST/DIN) or using the custom calibration solutions. • Automatic electrode diagnosis with pH slope and offset display.
ORP Mode: • 1 point offset calibration allows adjusting the displayed value to a known standard. • Relative and absolute millivolt modes provide the reliable ORP measurements.
Ion Mode: • 2 to 5 points calibration, containing the 8 concentration points can be selected. • Automatically recognizes the ion selective electrode, does not need to specify type of ion. • Direct ion concentration readout simplifies the measurement process. • Selectable concentration units include the ppm, mg/L and mol/L.
Conductivity/TDS/Salinity/Resistivity Modes: • 1 to 5 points calibration, automatically recognizes the conductivity standard solutions. • Selectable cell constant (0.1/1/10), reference temperature (20°C/25°C), TDS factor, linear and pure water compensations, seawater and practical salinity measurement modes.
Dissolved Oxygen Mode: • 1 or 2 points calibration using the air-saturated water or zero oxygen solution. • Salinity and barometric pressure compensations ensure the reliable DO measurements.
Other Features: • Automatic Temperature Compensation provides accurate reading over the entire range. • Calibration Due Alarm prompts user to calibrate the meter regularly. • Stability indicator shows when a measurement is recognized as stable. • Auto-Hold feature senses and locks the measurement endpoint. • Calibration report provides the details of the calibration standard and electrode slope. • Setup menu allows setting the 15 parameters, including the number of calibration points, stability criteria, temperature unit, auto-power off, etc. • Reset feature automatically resumes all settings back to factory default options. • Expanded memory stores and recalls up to 500 data sets. • Stored readings can be transferred into the computer by USB communication interface.
