Model C33 Two-sensor Input Conductivity Analyzer (measures conductivity, resistivity, TDS, or calculated measurement) Ultra-pure Water Capability. Model C33 accurately measures conductivity down to 0.056 µS/cm and resistivity up to 18.2 MΩ • cm, both at 25.0°C. Backlit LCD Readout. The two-line, 16 character backlit LCD provides excellent viewing contrast under all lighting conditions. Panel-mount 1/4 DIN Case. The C33 is housed in a 1/4 DIN, plastic case. Multiple Language Capability. All screens can be selected for display in English, French, German, or Spanish. (Other available languages can be substituted.) Unique DRY-CAL TM. The C33 is very easy to calibrate. Just enter the GLI-certified sensor “calibration constant.” Conventional wet sample and zeroing calibration methods are also provided. “Menu-guided” Operation. The simple keypad and logical menu structure make this analyzer easy to use. Menu screens guide you through setup, calibration, operation, and test/maintenance functions. Two 0/4-20 mA Analog Outputs. Each of the two isolated analog outputs can be set to 0-20 mA or 4-20 mA, and assigned to represent Sensor A or B’s selected measurement (conductivity, resistivity, or TDS), Sensor A or B’s temperature, or a calculated Sensor A and B measurement. During calibration, both outputs can be held at their present values, transferred to preset values, or remain active to respond to the measured value. Passcode-protected Access. For security, use the C33’s passcode capability to restrict access to configuration settings and calibration to authorized personnel only. Four Temp. Comp. Methods. Select from linear slope (% per °C), built-in ammonia temperature properties table, or built-in natural water temperature properties table to provide accurate temperaturecompensated measurements. A “no compensation” mode is also available. (For special solution compensation requirements, use GLI’s optional software tool kit to create a custom 10-point temperature table.) OEM Versions Available. These analyzers can be manufactured to accommodate OEM-specific needs. Simple Interactive Diagnostics. Built-in diagnostics continuously tests analyzer and sensor operation. CONTACTING CONDUCTIVITY/RESISTIVITY Multiple Measurements. Sensor A and B can be independently selected to measure conductivity (µS/cm or mS/cm), resistivity (MΩ • cm or KΩ • cm), or total dissolved solids (ppm or ppb). The measured values or temperatures for Sensor A or B can be displayed separately or together (four total measurements). Both analog outputs can also be displayed. The Model C33 can provide a calculated Sensor A and B measurement (% rejection, % passage, ratio A/B, ratio B/A, difference A-B, or difference B-A). Front panel red LEDs indicate relay “on/off” status.

Sensor A or B’s measured values or temperatures can be separately displayed, or all four measurements can be displayed together on one screen. Both outputs are displayed together on a screen. Also, a calculated Sensor A and B measurement can be displayed. Measurement Selectable Ranges • Sensor B temperature • Calculated Sensor A and B measurement Parameter (or calculated measurement) values can be entered to define the endpoints at which the minimum and maximum output mA values are desired.
