Aqualyzer® 9033 Sensor Unit
The sample flows through the flow switch, into the heat exchanger, passes through the constant head unit (used to stabilize minor changes in flow rate) and through the three solenoid valves. A vapor entrainment mechanism adds alkaline buffer vapor to the sample before it enters the sodium measuring flow cell and flows to drain. Calibration and grab sample are controlled automatically by the analyzer. Standard/grab sample liquid is brought into system via the three 3-way solenoid valves. A thermistor is housed in the flowcell and is used to detect the temperature of the sample/standard/grab sample. |

± 5% of reading or ± 0.01ppb to (whichever is greater) within ± 5°C of calibration temperature |
| Reproducibility |
|
± 5% of reading or ± 0.01ppb (whichever is greater) at constant temperature |
| Response

| Temperature
Compensation |
|
Automatic |
pH Compensation |
|
Alkaline vapor buffer: 0.88 SG (35% W/V) ammonia above 0.3 ppb sodium, 50% diethylamine solution below 0.3 ppb sodium. Analyzer drain allows for easy sample pH measurement. |

|
Manual and fully automatic calibration. Manual initiated by operator, automatic with programmable frequency in days. No manual changes of standards during calibration. |
| Current Outputs |
|
Two isolated 4-20mA current (analog) outputs |
| Digital Outputs |
|
Communication interface via RS-232 & RS-485 using MODBUS RTU protocol |
| Alarms |
|
Missing sample alarm and three additional voltage-free contacts, alarm points set from transmitter rated at 2A, 250VAC (non-inductive) |
| Power |
|
Wide range of input power supply 90VAC – 250VAC |
| CE Certification (on request) |
|
Meets low voltage and low electromagnetic compatibility directives |
