PCA 300 & PCA 301

Microprocessor-based Chlorine Analyzers for Process Control

Chlorine Monitoring

Chlorine is the most commonly used water disinfectant in applications that vary from treatment of drinking and waste water to pool and spa sanitization. The chlorine present in the water binds itself with bacteria, leaving only a part of the original quantity (free chlorine) to continue its disinfecting action.

Hanna Instruments, has completed its range of Portable Chlorine Meters, by offering the PCA 300 and the PCA 301 Chlorine Analyzers. These microprocessor-based process instruments can continuously monitor a sample stream for Free Chlorine or Total Chlorine content in the 0 to 5 mg/L range with a 0.01 resolution.

PCA 300, Free Chlorine Analyzer, and PCA 301, Total Chlorine Analyzer, are supplied complete with reagents (ready-to-use indicator and buffer solutions), tubing and instruction manual.

HI 98143 pH And Conductivity Transmitter With Isolated Output

  • HI 98143 is a pH and conductivity transmitter designed to accept signals directly from a pH electrode and a conductivity probe at the same time.
  • Direct connection of the probes to the transmitter assures a positive electrical connection with no signal loss. This transmitter is most useful in remote process control applications. The unit transmits 0 to 1 V output proportional to the input signals but independent of changes in load or cable capacitance.
  • Temperature compensation for conductivity measurements is performed by the transmitter's ATC circuitry.
  • The transmitter can be connected to any pH and conductivity controller, recorder, computer or any data monitoring device that accepts 0 to 1 V input.
  • HI 98143 is an ideal tool for applications such as hydroponics and greenhouses that require the monitoring of both pH and conductivity at once.
  • HI 98143 is supplied complete with instruction manual.

Hi-tech pH 500 Controllers: The New Measure of Value

pH 500 series of controllers offer exceptional value for your money. They are simple-to-operate, microprocessor-based process meters packed with features. For more flexibility and better resolution for chart recorders, any two points between 0 and 14 pH can be chosen to correspond to the analog output spans. Several pH 500 models are equipped with a bi-directional RS232C port. Push button password programming prevents tampering. The microprocessor memory is fully programmable and has 3 months backup power supply. The Fail Safe Alarm system protects the pH 500 against the pitfalls of process control, like power interruption or line failure.
With pH 500 quick 1, 2 or 3 point calibration at pH 4.01, 7.01 and 10.01 comes standard. The temperature can be manually or automatically compensated for. Increased automation has made computer compatibility a necessity for process control instrumentation. You can also choose from ON/OFF or Proportional Dosage to save on chemicals.
