Applications
General: Ideal
for virtually any batch type application where
pH or ORP control or adjustment is needed.
Use as ORP monitor for ozone systems and general
purpose pH monitor for all types of water
treatment and chemical processes.
Aquaculture:
Use for pH or ORP control in fish ponds and
tanks.
Industrial:
Use to treat batches of incoming process water,
rinse water treatment, recirculating system
and wastewater treatment. Suitable for pH
or ORP control of plating tanks and chemical
processing tanks. Ideal for low cost monitor
with alarms for batch and process applications.
Perfect for wastewater neutralization in small
and medium sized batches.
