The Hanna Instruments
PCA310
,
PCA320
,
PCA330
and
PCA340
series of chlorine, pH, ORP and
temperature analyzers are microprocessor controlled, process analyzers which continuously monitor a
sample stream for chlorine content, pH, ORP and temperature values.
The
PCA310
-
PCA340
monitor the free chlorine or total chlorine in the 0.00 to 5.00 mg/L range
depending on the factory settings and used reagents.
In the DPD Colorimetric method, N, N-Diethyl-p-phenylenediamine indicator and a buffer are mixed
with the sample.
The resulting chemical reaction causes a magenta color to form. The color intensity is proportional to
the concentration of chlorine. The color intensity is measured photometrically (with a light beam and a
photodetector) and converted to chlorine concentration, in mg/L, which is displayed on the front panel.
Indicator and buffer reagent bottles are placed directly into the instrument case. With a sampling period of
5 minutes, reagents need to be replenished about once a month. The reagent bottles are easily visible
through the transparent window allowing the operator to check the reagent levels.
PCA320
,
PCA330
and
PCA340
analyzers use
HI1005
probe to continuously measure the pH of
the sample stream in the range of 0.00 to 14.00 pH. The sample temperature is measured in the
5.00 to 75.00 °C range.
pH and temperature are displayed on the front panel. pH value is corrected with temperature.
PCA330
analyzer use
HI2008
platinum ORP electrode to continuously measure the sample ORP value.
The pH/temperature combined sensor and the ORP sensor are placed inside the case, directly in the
sample stream.
The case of
PCA310
-
PCA340
analyzers meet NEMA 4X, 12 and 13 standards. Molded fiberglass
polyester has outstanding chemical and temperature resistance.
The case provides wall mounting capability and door gasket assures a watertight and dust-tight seal.
The electrical and hydraulic connections are made through the side of the enclosure.
The front cover is secured with two lockable latches.
