Description:
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.
The device detects less than 0.05 mg or L (ppm) free ammonia and alerts you to the number 1 killer before any sign of stress.
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.
Care:
No care is required beyond removing algae with a clean, soft material.
Avoid touching the sensor with fingers, since skin oils can damage it.
Do not use bleach, soap, detergents or hard objects to clean the sensor. Some dye medications may discolor the sensor.
Sensitivity improves with age, provided the unit is not allowed to dry out, however, drying does not permanently impair the unit.
For maximum sensitivity, the unit should be read under natural daylight or daylight simulating light. Red enhancing light minimizes green and blue hues, decreasing the apparent sensitivity of the unit. The response of the unit may be checked by holding it briefly over the mouth of an ammonia bottle: color should develop rapidly.
pH Alert:
pH Alert is a unique color device designed to be placed in the aquarium or filter and monitor pH continuously. A sensor changes color reversibly to alert you shifts to in pH levels between 5.4 and 8.0. No tests, no strips, just constant readings. Freshwater Only.
Directions:
- Simply place pH Alert visibly anywhere in the aquarium or filter. It's that easy.
- No chemicals or test procedures are required.
- When first put in service, response time will be about 30 minutes.
- Thereafter, pH shifts will register within ten minutes.
Features:
- No test kits, chemicals, or procedures are needed
- It lasts over a year
- Marine or freshwater use
- It's small, clear & unobtrusive
