AQUASOL DIGITAL APCODM1 COD Meter | Chemical Oxygen Demand (COD) Testing Meter | Digital COD Photometer for Water & Wastewater Analysis

The AQUASOL DIGITAL APCODM1 Portable COD Meter is a microprocessor-based instrument designed for fast and convenient measurement of Chemical Oxygen Demand (COD) in water and wastewater. It uses a closed reflux method, supports standard vial sizes, and provides three measurement ranges up to 15,000 mg/L. The compact meter features a large LCD display and memory/storage functionality, making it suitable for on-site and laboratory COD testing.

Key Features

• Microprocessor-based COD measurement
• Designed for fast, reliable and accurate measurements
• Wide measurement range up to 15,000 mg/L
• Three COD ranges:
  • Low: 3–150 mg/L
  • Medium: 20–1,500 mg/L
  • High: 200–15,000 mg/L
• USEPA-compliant closed reflux method, as stated in the supplied product specification
• Suitable for standard vial size
• Wavelength range: 420–610 nm
• Fast response time of less than 3 seconds
• Large LCD display for convenient reading
• Memory and storage function
• Compact ABS housing
• Suitable for on-site and laboratory COD analysis

The broader AQUASOL product literature also describes its portable COD meter range as intended for wastewater and freshwater applications, including ponds and lakes.

Technical Specifications

Applications

The APCODM1 can be used for COD monitoring in:

• Wastewater treatment plants
• STP – Sewage Treatment Plants
• ETP – Effluent Treatment Plants
• Industrial wastewater
• Environmental laboratories
• Water-quality laboratories
• Freshwater monitoring
• Pond and lake water analysis
• Food & beverage industries
• Pharmaceutical industries

• Pollution-control applications

AQUASOL's published materials identify COD testing applications in wastewater and freshwater and describe the instrument as suitable for on-site and laboratory analysis.

How It Works

1. Prepare the water/wastewater sample using the appropriate COD digestion vial/reagent.
2. Digest the sample according to the applicable COD testing procedure.
3. Place the prepared standard COD vial into the meter.
4. Select the appropriate COD measurement range.
5. The meter performs the photometric measurement.
6. The COD result is displayed on the LCD.
7. Results can be retained using the meter's memory/storage function.

The AQUASOL COD system is based on closed-reflux COD measurement using standard-size vials.

Benefits

Portable Testing: Convenient for on-site water and wastewater analysis.

Wide COD Range: Three ranges cover low-, medium- and high-COD samples up to 15,000 mg/L.

Fast Measurement: The published APCOD series specification gives a response time of less than 3 seconds.

Easy Operation: Large LCD display and straightforward digital measurement.

Reduced Handling: Closed-vial testing avoids the traditional open-reflux titration approach described in AQUASOL literature.
