Frequently Asked Questions

Is this NATA-compatible for regulatory sampling?

The sampler itself is a compliant sampling platform. Chain-of-custody and sample integrity depend on your laboratory procedures. Ask about our NATA-compatible SOP template.

What reagents or consumables does it need?

Standard consumables: replacement intake hose (12 months), peristaltic pump tubing (6–12 months), and PE sample bottles. All stocked in Brisbane.

Can I trigger sampling from a PLC?

Yes. Dry contact input accepts any PLC trigger. RS485 Modbus also accepts remote sampling commands.
