가. Feature

1. pH / ORP Controller: The αlpha pH 200 controller is both a pH and an ORP controller–simply configure the controller via the keypad as needed.

2. Bright LED: New 14 segment alpha numeric 4-digit LED display is bright, clear and easy to read, even at a distance. Either pH or Temperature measurements can be viewed.

3. Fine Resolution of Readings: 4-digit LED allows 0.01 pH resolution and 1 mV for ORP.

4. Menu-driven Setup: 6 submenus accessible via the 4-button keypad, allows customization of operating parameters.

5. Push-button Auto-calibration: Single push-button activates calibration sequence. Buffer recognition feature quickens calibration process. Unique ‘OLD’›feature freezes relay activity during calibration setup.

6. USA / NIST Buffer Options: Both buffer sets are available in the same controller. Simply select the appropriate buffer in the calibration mode.

7. Dual Setpoints with Independent Hysteresis for Limit Control: Two Single Pole Double Throw (SPDT) relays are provided for limit control operations. Peripheral devices are protected by the ‘ysteresis’function which prevents relay-chattering.

8. Symmetrical Mode of Operation Eliminate fluctuating pH/ORP readings as a result of electrical noise in the application tank. Used in conjunction with the Potential Matching Pin (PMP) in the electrode, readings are stabilized.

9. Password Protection: Unauthorized and accidental tampering of configuration and calibration data is prevented by password access.

10. Temperature Compensation: pH readings can be automatically compensated for temperature fluctuations when Pt 100 sensor is attached. 3-wire system compensates for cable resistance. Manual temperature compensation is possible with separate inputs for Calibration and Process temperatures.

11. 4-20 mA, Galvanically Isolated Output: pH mode : 0.00 pH –4 mA & 14.00 pH –20 mA, ORP mode : -999 mV –4 mA & 1000 mV –20 mA Switch Mode Power Supply 85 to 260 VAC, 50/60 Hz or DC variable input allows controller to be used with wide supply voltages that might be available.

12. Panel Installation: Designed to 1/8 DIN size, installation is easy with the supplied accessories. Detachable plug-in connectors offer quick and easy attachment or removal of wires from controller.
