GLI Model C33 Contacting Conductivity Controller
Product #: C33A1NN

OBSOLETE ITEM

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.

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.

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.

Multiple Language Capability

All screens can be selected for display in English, French, German, or Spanish.
