Simple Deployment

How It Works

1
Unbox Remove Device from Packaging

The ACU arrives ready to deploy. No setup or configuration required.

2
Power On Press the Side Button Once

A solid green LED confirms collection is underway. Choose your deployment method:

Place in a fixed location for area-based testing Attach to a person via belt clip or shirt clip for personal monitoring
3
Collect Wait 1–16 Hours

The ACU runs a programmable collection cycle of 1 to 16 hours. Once started, collection cannot be stopped — this is by design to prevent tampering and ensure sample integrity.

4
Return Ship Back for Lab Analysis

Use the supplied prepaid return label to send the device back. Your sample is processed via ICP-MS for lead, cadmium, and other heavy metal detection.
