Installation of the PCA 311-331 Bromine, pH, ORP and
temperature analyzers should be undertaken by persons with
technical knowledge of the dangers associated with chemical
exposure and electrical shock.
Hanna Instruments assumes that persons performing the installation
tasks are aware of the appropriate safety procedures.
handling the supplied chemical reagents.
Locate the analyzer as close as is reasonably possible to the
point where the sample is withdrawn from the product stream
(referred to as the sampling point).
The instrument should be mounted indoors, out of direct sun-
light. Instrument operating temperature is 5 to 40°C (41 to
104°F).
Locate the sampling point to obtain a truly representative sample
from the product stream. For example, be sure the sampling
point is well downstream from a Bromine and acid / alkali
feed. This assures that adequate mixing and reaction of the
Bromine and acid / alkali before a sample is extracted.
Hydraulic connections should be installed only by qualified
personnel to assure conformity to applicable plumbing codes.
Direct routing of sample lines is recommended.
If the large process pipes are horizontal, taps should be
inserted vertically in the middle of the pipe to avoid pulling
sediment from the bottom or air bubbles from the top of the
pipe into the sample line.
A 1/2 BSP sample input fitting allows direct connection to the
optional input filter.
