Automatic Total Nitrogen/Phosphorus Monitoring System
TPNA-300
HORIBA supports your water quality monitoring needs, from installation space to maintenance.
Standard
Combined with a UV meter, you can cost effectively measure up to three components.
Standard TP/TN Monitor
Pure water can be supplied from the built-in water tank. The operation can be maintained by pure water supplementation during a routine maintenance service. This is a good choice for a user who has limited installation space.
*
|
Pure water supplementation cycle shall be once a week for continuous operation.

External pure water supply
Automatic pure water supply with no maintenance required.
TP/TN monitor with external pure water supply
If you have enough installation space, an external deionizer can be easily attached.
The ion exchange membrane needs to be replaced only once a year, making this a virtually maintenance-free model. If you have enough installation space, an external deionizer can be easily attached.

3-component water quality monitoring
Condenses a system for monitoring the three components targeted by the total load standards with a conventional COD monitor into one compact unit.
Combo model TP/TN/UV (COD) monitor
We recommend this 3-component combo model measurement monitoring for those who wish to replace their older UV meters but have limited installation space. This model allows you to measure 3 components while maintaining a small footprint.

Air purge cleaning prevents contaminant buildup
The sample water suction spout and intake pipe are purified through two rounds of pure water cleaning and air purging. Air cleaning (back flushing) is performed for approximately 30 minutes with the suction spout filter saturated with sample water so filter contamination and impurities are cleanly removed. After the back wash, the sample water is automatically kept above the liquid level, so it is not affected by the contaminants.

Optional Functions
•
|
UV load operation A COD load computation function can be built in (can be requested when the UV COD meter is being connected).
|
•
|
Sea water adjustment function By measuring the conductivity of the sea water density and adjusting the absorption, it is possible to eliminate the effect of bromide ions (Br-) in the sea water for measurement.
|
•
|
2-stage dilution range You can set a wide range of dilutions (total nitrogen 1,000 mg/L, total phosphorus 250 mg/L)for a variety of measurements.
