Description
Hanna Instruments® Chlorine, pH, ORP, and Temperature Analyzers, PCA320U-1
Features:
- Hanna PCA300 series chlorine analyzers continuously monitor, control, and adjust chlorine content and pH of sample stream
- From drinking and wastewater treatment to pool and spa sanitation, monitoring chlorine levels has an important bearing on public health as well as ROI and efficiency for heating system and industrial applications
- 4 models available for monitoring chlorine, pH, and ORP levels.
- Separate alarms can be set for chlorine, pH, ORP and temperature controls
- User-friendly interface simplifies setup and maintenance
- Four chlorine levels can be adjusted by the operator: proportional dosing setpoint, two alarm setpoints, and minimum level for dosing
- Three pH levels can be adjusted by operator: dosing setpoint and two alarm setpoints
- Two alarm levels can be set for temperature and ORP
- All alarms can be enabled or disabled
- System also offers overdosing protection that generates alarm if something within system is not working properly
- System will stop processes until the error is corrected by user
- Stores up to 3500 readings (at least 7 days at 3 minutes sampling interval) that can be available for consulting or downloading
- Logged records contain time stamp, full information about parameter values and alarm status at time
- Five analog outputs of 0-10 mV, 0-100 mV, 0-1 V, 4-20 mA or 0-20 mA are available to drive external devices, including connection to SCADA systems
- Analog output is fully programmable and can be proportional with chlorine concentration, pH, ORP or temperature value
- Limits of analog output are selectable for each parameter
- Control time cycle that can be set by user according to dimensions of controlled system
- Measurement process, dosing commands, and alarms can be performed according to this time cycle
- Range of cycle timing is from 3 to 90 minutes
- Unit can be wall mounted for easy accessibility
- Housing offers excellent chemical, mechanical and temperature resistance
