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 °C – 50 °C|
In July 2019 the MS3500 ammonia monitor featured on Dutch Television as part of a documentary on innovative water treatment technologies. Thanks to the support of our Dutch distributor, Technische Alliantie, the MS3500 has now been seen by tens of thousands of people all over the Netherlands.
The video describes how the ammonia monitor is used to measure levels of ammonia in a wastewater plant, using a contactless technology, based on the e-nose sensor and Henry's Law.
"This is a great advantage for the operators who don't need to worry about expensive cleaning routines associated with traditional ISE sensors."
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).
