Overview
Ammonia Alert® is an innovative color device for continuously detecting and monitoring toxic free ammonia.

A sensor changes reversibly from yellow to green to blue, relative to the ammonia concentration.

No test kits, chemicals, or procedures are needed.

The device detects less than 0.05 mg/L (ppm) free ammonia and alerts you to the #1 killer before any sign of stress.

It lasts over a year.

This product is not recommended for use at acid pH.

Marine or freshwater use.

In the absence of free ammonia the unit will assume a yellow or faint yellow-green color. It is normal for the dry sensor to have a greenish hue. It may take up to a few days for a dry sensor to equilibrate with the water. No sampling of water, chemicals, or test procedures are required. The presence of the free ammonia is detectable continuously with a response time of about 15 minutes. Response to decreasing ammonia is slower, requiring about 4 hours to go from TOXIC to SAFE on removal of ammonia.
