Portable Ammonia Nitrogen Colorimeter
Short Description
This portable Lohand ammonia nitrogen colorimeter uses the salicylic acid photometric method at 620 nm to measure 0.00–2.00 mg/L with ±5% precision. It delivers fast results consistent with international methods, weighs just 220 g and runs more than 40 hours on a single 9V battery, ideal for water quality testing in the field or the lab.
Portable Ammonia Nitrogen Colorimeter
This portable Lohand colorimeter provides rapid detection of ammonia nitrogen concentration in water. Using the salicylic acid photometric method at 620 nm, it measures 0.002.00 mg/L with results consistent with international methods. Its compact body works equally well in the laboratory and in the field.
Key features

- Runs more than 40 hours on a single 9V battery
What is ammonia nitrogen?
Ammonia nitrogen (NH3-N) is the nitrogen present in water as free ammonia (NH3) and ammonium ions (NH4+). Nitrogen-containing organic matter, especially human and animal waste, readily breaks down into ammonia, so a rising ammonia nitrogen level signals organic contamination. It is a key parameter in wastewater testing and in aquaculture ponds.
