CD Digital Conductivity Meters has features - high stability, reproducibility, and continuous duty cycle.

The model APX 185 LABORATORY conductivity meter incorporates a J FET controlled oscillator and EPROM switching, with automatic ability to choose 100Hz to 1000Hz operation. It has a relative accuracy of ±1 least digit of selected range, repeatability of ±1 least digit and stability (drift/24hrs) after warm up of 30 minutes of less than 1 least digit.

SALIENT FEATURES

WIDE MEASUREMENT RANGE From 200nS/cm to 200mS/cm (1S = 1 mho) HIGH SENSITIVITY 100pS/cm using 0.01 cell constant. DIRECT DISPLAY OF CONDUCTANCE The display is in conductance mS/cm and µS/cm (conductivity x cell constant) eliminating cell constant determination and user multiplication. AUTOMATIC TEMPERATURE COMPENSATION With an optional NTC probe, the conductivity variations of the sample with temperature compensated.

RATIOMETRIC MEASUREMENT Using two conductivity cells the instruments can be used as a conductivity comparator for quality control "GO-NOGO" tests. AUTOMATIC SELECTION OF OPTIMUM FREQUENCY The instrument automatically chooses the internal frequency of 100Hz or 1000Hz to suit the measurement range for very high accuracy readings. DIGITAL READOUT Bright 3 ½ digit 7 segment LED display for ease of observation for readings from 0.0001µS/cm to 19.99 mS/cm

UNIQUE FEATURES

Measurements in conductivity are done for determining the conductance of samples (ie. conductivity displayed on the usual meters multiplied by the cell constant of cell). The user has to determine the cell constant accurately from time to time and use this to multiply the displayed reading and obtain CONDUCTANCE in S/cm. the CD CONDUCTIVITY METER accurately determines the cell constant during calibration, multiplies and displays CONDUCTANCE DIRECTLY ensuring the highest accuracy possible.

Another unique feature is the Two dimensional electrode stand with a flexible spring balanced arm.

Along with the Conductivity Meter we provide a 1.0 cell K sensor, electrode stand, electrode holder, wash bottle, calibrating standards, a dust protective cover and a handy Plastic Instruction manual.
