Application :

Application of 84051 AZ Combo Water Meter-pH / Conductivity / SALT / TDS / D.O:
The 84051 Combo Water Testing Meter can measure the pH, Conductivity or TDS or Salinity and Dissolved oxygen depend on which kind of probe attach to the meter. So the 84051 Multiple Parameters Water Testers could be operated as the pH meter, conductivity meter, TDS meter, Salinity meter or D.O. meter as user needed.

User could change the probe or screw on the 84051 Combo Water Quality Measuring Instrument easily. And in order to avoid broken by the stone or particle attacking in the measuring environment, we have developed the specific anti-collision cap on each probe. So the 84051 Combo Water Testing Meter would be the best tool for all professional measuring purposes, including the Aquaculture, Aqua farm, LAB, swimming pool or water treatment business, or other related industry, no matter the fresh or sea water.

The 84051 AZ Combo Water Meter-pH / Conductivity / SALT / TDS / D.O has the back light function, which could help user to operate the measurement in the dark area.

AZ 84051 Combo Water Meter- pH/Conductivity/Salt/TDS/D.O was being designed and manufactured by AZ Instrument, a well experienced manufacturer for Environmental Measuring Instrument.

FAQ :

【FAQ of AZ 84051 Multi-Parameter Water Quality Meter with Interchangeable Probes】


Q1: What does the E01 error mean?
A: E01 indicates an internal system error that cannot be resolved by the user. Please contact your dealer or authorized service center for assistance

Q2: What does the E21 error mean during DO measurement?
A: E21 indicates that the temperature difference between the calibration environment and the measured sample exceeds 10 °C. Reduce the temperature gap or pre-measure a sample with an intermediate temperature before measuring the target

Q3: What does the E13 error mean and how can I fix it?
A: E13 indicates a pH error. Please perform a 3-point pH calibration again using fresh standard buffer solutions to resolve the issue.
