About this equipment

Features:

PH:

1. Multiparameter water quality meter is equipped with a 3.5 inches backlit LCD display.

2. 1 to 5 points calibration with automatic recognition for USA, NIST and DIN buffers.

3. Automatic electrode diagnosis shows the pH slope and offset.
ORP:

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

2. Relative and absolute millivolt modes ensure the reliable ORP measurements.

Ion Concentration:

1. 2 to 5 points calibration, including the 8 concentration points can be selected.

2. Direct ion concentration readout simplifies the measurement process.

3. Automatic electrode diagnosis shows the calibration points and slopes.

4. Selectable concentration units(ppm, mg/L, mol/L, mmol/L) and ionic valency.  
Conductivity/TDS/Salinity/Resistivity:

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

2. Selectable cell constant, reference temperature, TDS factor, linear and pure water compensations, seawater and practical salinity measurement modes.

3. Automatic electrode diagnosis shows the calibration points and factors.

Dissolved Oxygen:

1. 1 or 2 points calibration using the air-saturated water or zero oxygen solution.

2. Salinity and barometric pressure compensations eliminate the measurement error. 

Other Features:

1. Automatic temperature compensation ensures accurate readings over the entire range.

2. Auto-Read function senses and locks the measurement endpoint.

3. Calibration due alarm prompts user to calibrate the meter regularly.

4. Auto-Power Off effectively conserves battery life.

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

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

7. Expanded memory stores or recalls up to 500 data sets.

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

9. Multi-mode power scheme(batteries, power adapter and USB port) ensures that using the meter smoothly.

Accessories:

pH/conductivity/dissolved oxygen electrode, temperature probe, pH standard buffer, conductivity standard solutions, dissolved oxygen electrolyte, membrane cap, carrying case.
