The MS3500 is the first ammonia monitor for Raw Waste Water. Its rugged construction and design allows it to reliably measure Ammonia at the very front end of a waste water treatment plant, giving the operator a level of control and knowledge presently unknown to the industry. It is used to:
|Dynamic Range||1 ppm – 200 ppm in water|
|Absolute Accuracy||Ammonia in Water: ±10%|
|Repeatability||Repeated measurement, 5ppm Ammonia in Water: ±2%|
|Sampling Frequency||60/30 minutes (Contact us for other sampling periods)|
|Relays||2x, User Programmable function|
|Analogue Output||4 – 20 mA, Loop Resistance 40 Ω – 1k Ω|
|Digital Outputs||Modbus, Profibus as options|
|Typical Power Consumption||70 W in normal operation|
|NaOH Requirement||10 l of 1 M NaOH per 15 Weeks|
|Operating Temperature||1 – 50 °C|
The MS3500 utilises a contactless measurement technique based on Henry’s Law, sensing headspace gases or volatiles in the sampling tank provided, and provides a measurement system with very low maintenance requirements.
Thanks to the clever design and technology the sensor never touches the water. This results in no sensor cleaning , reduced drift, virtually no fouling and very low maintenance.
The MS3500 is accurate to low ppm concentrations and its wide dynamic range allows it to be used in a wide variety of environments. Using minimal reagents and consumables the running costs of the system are very low.
The MS3500 is accurate from 1 to 200 ppm and its wide dynamic range allows it to be used in many applications.
A sample of gas is then taken from the headspace, passed through the sensor and the response analysed to provide a concentration in ppm of the ammonia in the water (Fig. 2).
