Water Samplers - Sigma 900 Series

Supplier: Envirorent

A water sampler is a tool that allows you to prove or verify regulatory compliance and is your primary source of information about the character of a discharge or receiving body of water.

Price Guide: POA

Sound control measures are based upon the right information. The Sigma 900 series samplers are the best water samplers you can buy, and should be part of any proactive water quality measurement system.

Repeatable sample volume at a timed interval or after a predetermined volume of flow, the Sigma 900 series samplers provide the simple operation and reliability that you depend on.

Sampling for regulatory compliance, monitoring or combined sewer overflows, storm water outfalls, biomonitoring and water quality research may demand a sampler with greater sophistication and capability.

  • Battery or A/C Powered.
  • Single or Multiple Bottles.
  • Highest Sample Integrity for data you can count on.
  • Simple to Understand, Efficient to Use.
  • Small and Lightweight, handling is made easy.
  • Built to last with rugged construction and a sealed controller.

Ideal for:

  • NPDES Storm Water Compliance.
  • Pretreatment Compliance.
  • Storm Water Runoff Monitoring.
  • CSO (combined sewer overflow) Monitoring.
  • Regulatory Compliance Monitoring
  • Biomonitoring
  • Water Quality Research
