VTSYIQI Multiparameter Water Quality Meter pH mV Conductivity TDS Salinity Resistivity DO Temp Meter 1 to 5 points calibration

Shippnig Policy :Battery /Liquid /Powder can not be included during the Shipping

High-performance multiparameter water quality meter contains the 8 measurement modes, the meter is suitable for measuring the pH, conductivity, TDS, salinity, resistivity and dissolved oxygen. (If you want to measure ORP, ion concentration, you need to purchase additional electrodes)

pH Mode:

• Portable multiparameter water quality meter is equipped with a backlit LCD display.

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

• Automatic electrode diagnosis shows the pH slope and offset.

ORP Mode: (ORP Probe is optional)

• 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 Mode(Ion Probe is optional)

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

• Direct ion concentration readout simplifies the measurement process.

• Automatic electrode diagnosis shows the calibration points and slopes.

• Selectable concentration units (ppm, mg/L, mol/L, mmol/L) and ionic valency.

Conductivity/TDS/Salinity/Resistivity Modes:

• 1 to 5 points calibration with automatic recognition for conductivity standards.

• Selectable cell constant (K=0.1/1/10), reference temperature (20/25°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 eliminate the measurement error.
