Overview
The Oakton CON 6 conductivity meter is a microprocessor-based handheld meter designed for fast, accurate measurement of water conductivity and total dissolved solids (TDS). This meter measures conductivity and temperature to help determine the concentration of chemistry in the wash bath. Ideal for laboratory, field, and industrial applications including boiler blow-down water, cooling towers, and process water monitoring.
Key Features
- Five auto-ranging measurement modes — up to 200.0 mS (200.0 ppt)
- Automatic temperature compensation (ATC) for high accuracy in changing temperature conditions
- Single-point calibration covers all five ranges; single points can be calibrated within each of the five measurement ranges
- Hold function and auto-off function that shuts meter off after 20 minutes of nonuse
- Includes protective rubber boot with stand and conductivity/temperature probe (K = 1.0)
- Customizable for temperature compensation, temperature coefficient, normalization, and cell constant
Technical Specifications
The CON 6 offers the following technical capabilities:
- Measurement Range: 0–200.0 mS (milliSiemens)
- Temperature readout in °C with the push of a button
- Cell Constant: 1.0 (fast-response probe)
- Calibration: Automatic or manual, five-point capable
- Power: Four AAA batteries
- Auto-off: 20 minutes of inactivity
- Includes rubber boot with built-in stand
Typical Applications
The Oakton CON 6 is suitable for:
- Water quality and purity testing in industrial processes
- Boiler and cooling tower monitoring
- Environmental and laboratory analysis
- Process water and effluent testing
- Wash bath concentration monitoring in industrial cleaning
- Field measurements in HVAC and water treatment systems
