Traditional COD Monitoring Is Costing You More Than You Think
If you are still relying on reagent-based COD analysis, you are absorbing costs and operational headaches that simply do not need to exist in 2025.
Reagent Costs Never Stop
Mercury, silver sulphate, potassium dichromate — the consumables bill adds up year after year with no end in sight.
Hours Waiting for Results
Traditional COD digestion takes 2–6 hours. By the time you have an answer, the process event has already passed.
Hazardous Chemical Handling
Heavy metal reagents create WHS obligations, disposal costs, and ongoing staff risk that compound over time.
Lab Dependency & Bottlenecks
Sending samples off-site means waiting. You cannot respond to effluent exceedances or process upsets in real time.
Introduce the COD ID BLACK UV — Instant, Accurate, Chemical-Free
The COD ID BLACK UV uses UV absorption at 254 nm to deliver continuous, in-line COD, turbidity, and UV254 readings — no reagents, no maintenance windows, no lab. Just data, in seconds.
10-Second Response
Continuous measurement every 10 seconds. Catch process upsets before they become compliance violations.
Zero Reagents
UV optical technology means no chemicals, no consumables, no hazardous waste. Calibrate every 3 months and you are done.
Multi-Parameter
Simultaneously measures COD (0–6000 mg/L) can be calibrated for your range, UV254, turbidity (0–10,000 NTU), and temperature in a single probe.
Drop-In Installation
IP68-rated stainless steel probe with RS485 Modbus RTU output. Connects directly to your existing SCADA/PLC.
Verified Accuracy
≤±5% accuracy and ≤3% repeatability — reliable enough for regulatory reporting, not just indicative trending.
Ultra-Low Power
Runs on 12/24VDC at under 0.6 W. Suitable for remote and solar-powered monitoring locations.
5-Year Cost Comparison: Reagent vs. Optical
The numbers speak for themselves. Here is what facilities typically spend over 5 years.
Traditional Reagent Method
$236K Estimated 5-year total cost- Reagent consumables: ~$18,000/yr
- Lab technician time: ~$22,000/yr
- Equipment maintenance: ~$6,000/yr
- Hazardous waste disposal costs
- Ongoing WHS compliance obligations
COD ID BLACK UV (Optical)
$27.8K Estimated 5-year total cost- One-time instrument purchase
- No reagent costs — ever
- Minimal maintenance (3-month calibration)
- Zero chemical disposal costs
- Real-time data, no lab delays

How It Works
Simple to install, simple to operate. No chemistry degree required.
Install In-Line
Mount the IP68-rated stainless steel probe directly in your channel, pipe, or tank. No flow cell required.
Connect to Your System
RS485 Modbus RTU output connects to your existing PLC, SCADA, or data logger. Readings start immediately.
Monitor in Real Time
COD, turbidity, UV254, and temperature — all live, all continuous, with a 10-second update cycle and ≤±5% accuracy.

Frequently Asked Questions
How accurate is UV optical COD compared to traditional lab methods?
The COD ID BLACK UV achieves ≤±5% accuracy and ≤3% repeatability — well within the range required for trade waste compliance reporting and a direct operational replacement for bench-top COD analysis in most applications.
Will it work in high-turbidity dairy effluent?
Yes. The sensor measures turbidity simultaneously and compensates for it in the COD reading. It has a turbidity range of 0–10,000 NTU, covering even the most demanding dairy wash and CIP effluents.
Does it need a flow cell or is it direct-immersion?
The probe is designed for direct immersion — mount it in your channel, wet well, or tank. No flow cell, no bypass plumbing, no extra civil works required.
How does it integrate with our existing SCADA system?
The probe outputs RS485 Modbus RTU, compatible with virtually all industrial PLCs, SCADA systems, and data loggers. Our technical team can advise on integration for your specific setup.
How often does it need to be calibrated?
Every 3 months — a simple clean and check with no reagents to prepare. Ongoing maintenance is minimal compared to any reagent-based method.
Can I get a quote before buying?
