Conductivity Meter

Control Dynamics offers a conductivity meter that has all the features, which were built into the pH meter - high stability, reproducibility and a continuous duty cycle. The model APX 185 laboratory conductivity meter incorporates a J FET controlled oscillator ad EPROM switching, with automatic ability to choose 100Hz operation. It has a relative of ? least digit of selected range, repeatability of ? least digit and stability (drift 24 hrs) after warm up of 30 minutes of less than 1 least digit. Salient features: wide measurement range from 200 nS/cm to 200 mS/cm (1S = 1 mho); high sensitivity - 100 pS/cm using 0.01 cell constant; direct display of conductance - the display is in conductance mS/cm and mS/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 is compensated; ratiometric measurement - using two conductivity cells the instruments can be used as a conductivity comparator for quality control "Go-No Go"tests; automatic selection of optimum frequency - the instrument automatically chooses the internal frequency of 100 Hz or 1000 Hz to suit the measurement range for very high accuracy readings; and digital readout - bright 3-1/2 digit 7-segment LED display for ease of observation of readings from 0.0001 mS/cm to 19.99 mS/cm.
