 PH900P Portable Multi-parameter Water Quality Meter/ portable water quality analyzer(automatic Range conversion)

• pH Mode:

Up to 5 points push-button calibration with auto-buffer recognition.

selectable pH buffer standards, resolution and temperature units.

Automatically calculates and  displays electrode slope  that helps you decide whether to replace pH electrode.

• ORP Mode:

Single point  offset calibration allows user  adjusts displayed value to a known standard.

Absolute or Relative  mV measurements provides accurate readings.

• Ion Mode:

Standard BNC connector can connects many Ion selective Electrode.

2 to 5 points push-button calibration from low to high concentrations.

selectable multiple concentration units, including ppm, mg/L, mol/L.

Direct readout ion concentration simplifies measurement process.

mV measurement allows user to check performance of ion electrode.v

• Conductivity/TDS/Salinity Mode:

Up to 5-point push-button calibration allows user to uses customized calibration solutions.

Adjustable TDS factors, cell constants, temperature coefficients and normalization temperature.

selectable linear or pure water compensation modes.

In salinity measurement modes, selectable practical salinity (PSU) or seawater measurement standard (ppt).  

• Dissolved Oxygen Mode:

1 or 2 points auto-calibration (100% in saturated air or air-saturated water, 0% in zero oxygen solution).

Manual salinity and barometric pressure compensation.

selectable readout in ppm, mg/L or percentage saturation.

General Features:

• Automatic Temperature Compensation  (ATC)  ensures highly accurate measurements over the entire range.
• Calibration due reminder helps you to calibrate meter regularly.
