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.
