86031 AZ IP67 Combo Water Meter-pH/COND./SALT/TDS/D.O features:
* Large LCD to display multiple parameters simultaneously:
pH, Conductivity or TDS or Salinity, Dissolved oxygen, Temperature (by using different probes)
* Displayed parameter is decided by probe type
* Water proof function as IP67
* Fast measuring of dissolved oxygen value
* Accurate replaceable probes with anti-collision cap
* Auto ranging for conductivity measurement
* Auto temperature compensation (ATC)
* 99 points memories w/recall function
* Multiple points calibration: 3 points for pH, 1 point for D.O., 4 points for conductivity
* Manually altitude and salinity compensation function for D.O. measurement
* Easy replacement probes
* Temperature unit ℃/℉ is switchable
* 1 hour auto power off
* Excellent to use in fresh or sea water aqua farm
Application of 86031 AZ IP67 Combo Water Meter-pH /
Conductivity / SALT / TDS / D.O: AZ 86031 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.
The 86031 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 or user could attach three kinds of
probes at the same time. So the 86031 Multiple
Parameters Water Testers could be operated as the pH meter,
conductivity meter, TDS meter, Salinity meter or D.O. meter as user needed.
We design different color connector on the meter, user only needs to screw on
the probe with the same color, and then get the measuring reading accurate and
fast.
User could change the probe or screw on the 86031 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
86031 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.

【FAQ of 86031 AZ IP67 Combo Water Meter-pH / Conductivity / SALT / TDS / D.O】
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.
