KWQ-86032 ODO / pH / COND / SALT / TDS / Temp. Meter (IP67) KEPLER

6 Parameter Water Quality Meter KEPLER KWQ-86032 (ODO / pH / Conductivity / Salinity / TDS / Temperature Meter)

KEPLER KWQ-86032 Multi-Parameter Water Quality Meter is a portable water quality meter for measuring dissolved oxygen in water (Optical Dissolved Oxygen: ODO), acidity and alkalinity (pH), electrical conductivity, salinity, total dissolved solids (TDS) and temperature, all six parameters in one device. It is suitable for water quality inspection, aquaculture, wastewater treatment systems, and field testing.

The meter uses optical dissolved oxygen measurement technology which relies on the signal changes from oxygen-sensitive materials to assess the concentration of oxygen in water. This reduces maintenance steps compared to some electric chemical DO probes and does not require polarization time before use.

KWQ-86032 can measure ODO levels within a range of 0.0-20.0 mg/L or display oxygen saturation percentage from 0.0-199.9%, with customizable compensation for altitude and salinity effects to ensure accurate measurements in different environments.

The meter supports pH measurement ranging from 2.00-12.00 pH, conductivity up to 150.0 mS/cm, and salinity up to 42.0 ppt, with TDS calculation based on the adjustable TDS factor between 0.30-1.00.

The device features a large LCD display for multi-parameter readings and can connect simultaneously to pH, conductivity, and ODO probes, each probe type being interchangeable for easy maintenance and task-specific use.

With an IP67 protection level design and the use of 4 AAA batteries, it is ideal for water quality testing in field conditions and industrial applications as specified by the manufacturer.

TECHNICAL SPECIFICATIONS

Meter Measurement Parameters Details

1. Optical Dissolved Oxygen (ODO)

Measures dissolved oxygen in water using optical technology, supporting a concentration range of 0.0-20.0 mg/L and percent saturation of 0.0-199.9%. Accuracy is ±3% F.S., with support for two-point calibration.

The optical sensor does not require polarization before use and supports manual compensation for altitude and salinity to adjust the DO measurement according to environmental conditions.

2. pH - Acidity-Alkalinity Value

Measures acidity-alkalinity values in water within a range of 2.00-12.00 pH, with a resolution of 0.01 pH and accuracy of ±0.1 pH. Supports up to three-point calibration, suitable for general water quality inspection and wastewater treatment processes.

3. Conductivity (EC) - Electrical Conductance

Measures electrical conductivity in units of µS/cm or mS/cm across four measurement ranges, with a maximum range of 150.0 mS/cm. Accuracy is ±1% F.S. ±1 Digit, suitable for water quality inspection and approximate concentration determination of ionic solutions.

4. Total Dissolved Solids (TDS)

Displays an estimated amount of dissolved solids based on electrical conductivity using a TDS factor adjustable between 0.30-1.00. The displayed value depends on the conductivity and conversion factor set.

5. Salinity - Salt Content

Measures or displays salt content in water within a range of 0-42.0 ppt according to the seawater model, suitable for aquaculture water quality inspection and salinity tracking.

6. Temperature - Temperature Measurement

Measures temperature from -5.0 to +60.0°C with a resolution of 0.1°C and accuracy of ±0.5°C. Note that the ODO sensor supports up to 50.0°C according to the catalog data.

Detachable Sensor System

KWQ-86032 supports connection to 3 types of probes, namely pH Probe, Conductivity Probe and ODO Probe, which can be used simultaneously according to the supported configurations. Each probe type can be detached for easy maintenance.

The probes have protective covers that prevent impact damage, suitable for field measurements. It is recommended to check the condition of the probes and connectors before starting each measurement.

Multi-Point Calibration System

• ODO Calibration: Supports 2-point calibration
• pH Calibration: Supports 3-point calibration
• EC / TDS / Salinity Calibration: Supports 3-point calibration

The calibration should be performed according to the manufacturer's manual, using appropriate standard solutions for parameters and measurement ranges. Ensure that probes are clean and in good condition before starting calibration.
