Remove the analyzer from the packing material and examine it carefully to make sure that no
damage has occurred during shipping. If there is any noticeable damage, contact your local Hanna
Instruments Office immediately.
Each analyzer is supplied complete with:
• 2 pcs. reagent bottles (1 pc. indicator and 1 pc. buffer solution)
• 2 pcs. reagent bottle caps
• 5 pcs. DPD compound powder
• tubing
• Instruction Manual
Note: Save all packing materials until you are sure that the instrument functions correctly. Any
damaged or defective items must be returned in their original packing materials together with
the supplied accessories.
Warning: The PCA310 - PCA340 series of Chlorine, pH and ORP Analyzers are not designed
for use with samples that are inflammable or explosive in nature. If any sample solution
other than water is used with these products, test the sample/product compatibility to assure
user safety and proper product performance.
Safety Precautions: Please take the time to read the safety precautions carefullywherevertheyappear
inthis manual.They are provided to prevent personal injury and damage to the instrument. This safety
information applies to the operators and service personnel and the following two captions are used:
CAUTION: identifies conditions or practices that could result in damage to the instrument or persons.
Warning: Identifies conditions or practices that could result in personal injury or loss of life.
Note: Because of the inherent dangers in handling chemical samples, standards and reagents,
HANNA Instruments strongly recommends the users of this product to review the Material
Safety Data Sheets and become familiar with safe handling procedures and proper usage prior
to handling any chemicals.
PRELIMINARY EXAMINATION

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.

Four chlorine level setpoints can be adjusted by the operator: a proportional dosing setpoint, two alarm
setpoints and a minimum level for dosing. The proportional dosing factor (1/∆ is user selectable with
a delta between 0.1 and 5.0 mg/L (ppm)). Chlorine dosing system controls a SPST relay.
Each chlorine alarm can be enabled or disabled.
Three pH level setpoints can be adjusted by the operator: a dosing setpoint and two alarm setpoints.
The pH control mode is user selectable: on/off or proportional dosing.
The proportional dosing factor (1/∆) is user selectable with a delta between pH 0.1 and 2.0 . The
on/off dosing hysteresis is user selectable between pH 0.05 and 2.00.
pH dosing system controls a SPST relay.
Each pH alarm can be enabled or disabled.
For temperature and ORP, two alarm levels can be set by the user.
Each temperature or ORP alarm can be enabled or disabled.
Alarm condition controls a SPDT relay.
A system error feature provides relay activation to signals need for operator intervention.
System error condition controls a SPST relay.
For PCA310 - PCA330 series the voltage output ranges of 0-10 mV, 0-100 mV, 0-1 V or a current
output of 4-20 or 0-20 mA are available to drive an external device such as a chart recorder.
The analyzer can drive a proportional dosing pump through the 4-20 mA output, for chlorine or for
acid/alkali dosing.
PCA340 has two current outputs of 4-20 or 0-20 mA are available to drive external devices such as
chart recorders.
The analyzer can drive two dosing pumps through the 4-20 mA outputs for chlorine and for
acid/alkali dosing.
The analog output is fully programmable and could be proportional with chlorine concentration, pH,
ORP or temperature value. The limits of the analog output is selectable for each parameter.
The analyzer can store up to 3500 readings (at least 7 days at 3 minutes sampling interval), that are
available for consulting or downloading.
The PCA310 - PCA340 analyzers can be monitored or controlled through RS485 or GSM network
connection.
Errors, alarms and warnings are sent through SMS (using GSM module HI504900).
The analyzer state can be interrogated by a simple call using GSM phone.
GENERAL DESCRIPTION

Case dimensions in mm & inches
Time is displayed on the main panel and a time related warning system for “Old calibration”,
“Reagent expired” and “SIM expired” is available.
The language for user interface can be easily changed without restarting the analyzer.
