VTSYIQI Portable pH/Dissolved Oxygen Meter Multiparameter Water Quality Meter with Conductivity Standard Solutions Range 0.00 to 20.00 mg/L/ 0.0 to 200.0% Saturation Manual/Auto-read Measurement Endpoint E201-BNC pH Electrode

About this item

High-performance multiparameter water quality meter contains 3 measurement modes, suitable for measuring pH, ORP and dissolved oxygen.

Automatic temperature compensation ensures accurate readings over the entire range.

Calibration due alarm reminds the user to calibrate the meter regularly.

Auto-read function senses and locks the measurement endpoint.

Setup menu allows setting the number of calibration points, stability criteria, temperature unit, date and time, etc.

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 zero offset.

ORP Mode:

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

Relative and absolute millivolt modes ensure the reliable ORP measurements.

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 errors.

Other Features:

Automatic temperature compensation ensures accurate readings over the entire range.

Auto-read function senses and locks the measurement endpoint.

Auto-power off effectively conserves battery life.

Reset function automatically resumes all settings back to the factory defaults.

Expanded memory stores or recalls up to 500 data sets.

USB communication interface is easy to transfer data to a PC.

Multi-mode power scheme (batteries, power adapter, USB port) ensures the smooth operation of the meter.
