CAC Gas & Instrumentation
Water & Waste Water Treatment
Gas references from treatment plant to laboratory.
Calibration gases, sample conditioning and gas delivery equipment for water utilities, wastewater facilities and analytical laboratories.
Defined gas specifications
Composition selected for your instrument and method.
Compatible delivery equipment
Cylinders, regulators and gas control for the application.
Application support
Discuss your requirements with the CAC Gas team.
Overview
Start with the measurement you need.
Match the reference and delivery method to the measurement environment. CAC Gas can assist with detector test mixtures, low-level gas measurements and laboratory gas supply for treatment facilities.
Tell us the instrument, gas specification and expected usage. Our team can help identify a suitable reference and gas delivery arrangement for your application.
Applications
Match the reference to the task.
Choose the mixture, concentration and delivery conditions for the specific detector, analyser or method.
Treatment & odour measurement
Reference and generation options for chlorine-related instruments and low-level hydrogen sulphide monitoring.
Sampling & laboratory analysis
Sample conditioning, analytical references and controlled gas supply for plant measurement systems.
Gas & supply options
Define your gas specification.
These examples are a starting point for an enquiry. Exact composition, certification, packaging and current availability are confirmed for the selected product.
| Reference or supply option | Typical measurement task | What to specify |
|---|---|---|
| Multi-gas and single-gas mixtures | Portable and fixed detector testing | Specify the sensor set and required concentrations. |
| Low-level H2S references | Odour monitoring analyser checks | Discuss source concentration and dilution or generation needs. |
| Chlorine dioxide and ozone calibrators | Instrument testing with generated challenge gas | Confirm target concentration and flow. |
| Gas sample conditioning | Sampling under humidity and contamination challenges | Describe the sample and the analytes to be measured. |
Ask about traceable, certified and accredited reference options where required. Accreditation and certificate scope apply to the selected product and producer.

Include humidity, particulate, temperature and sample pressure when discussing conditioning. The system must be evaluated for the target analytes as well as the environment it samples.
Include your delivery location and required date so cylinder selection, expected use and supply arrangements can be discussed together.
Common questions
Before you specify a gas.
Can CAC Gas support low-level odour monitoring?
Discuss your hydrogen sulphide analyser and target range. CAC Gas can assess cylinder references and suitable calibration or dilution options for the required measurement level.
Can I request a custom gas mixture?
Send the required components, concentrations, balance gas and uncertainty or certification requirements. CAC Gas will confirm mixture feasibility, cylinder options, shelf life and lead time with your quotation.
What should I include in my enquiry?
Include the instrument make and model, analytical or test procedure, gas specification, usage, cylinder connection and flow requirements. Add the delivery location and required date so the team can prepare a suitable quotation.
