Ammonia test paper showing 0,5,10,20,50,100 ppm (parts per million). 1 roll per box with one dispenser supplied. Use for testing the levels of ammonia, in the chicken coop, or on the poultry layer farm or broiler farm, free range, pastured poultry or broiler farm. Knowing ammonia levels is a very good measure/indicator of chicken, duck, or any poultry environment.
It is best to measure Ammonia at the level a chook will notice or feel the affects of ammonia, so for a broiler which sits down a lot measure at sitting height, for a chicken or layer measure a tiny bit higher but the more conservative the better to ensure your poultry welfare is OK. If ammonia is too high broilers in particular can get burnt feet, and become overwhelmed.
Above 20ppm is not good.
Follow your biosecurity procedures, regarding clean hands and/or gloves etc. Tear off a 2.5cm strip of ammonia test paper, moisten with distilled water and expose to the air at appropriate height. Wait 15 seconds (have a timer handy) and compare the test strip to the calibrated color chart on the dispenser pack. The color chart shows readings in ppm of ammonia in air.
