Model 2052 Digital Conductivity Meter

Discontinued – out of production

  • Measure six ranges of Conductivity
  • Portable meter operates on single 9 Volt battery
  • Ideal for use in the field or laboratory
  • Digital display ½" high, 3 ½ digit with floating decimal
  • Easy to use and calibrate
The Model 2052 features three modes of operation, two for the measurement of solution conductivity over six decades from .001 micro Siemens (µS) to 200 milli Siemens (mS) and one for Self Check. The Self Check feature allows for verification of proper operation, the ability to adjust for cell constant variations and Total Dissolved Solids (TDS) scale factor. The conductivity and TDS measurement data is displayed on a 3 ½ digit Liquid Crystal Display (LCD) with floating decimal.

The Function switch selects Power Off, Automatic Temperature Compensation (ATC) On, Off, or Self Check. The ATC is set at 2% per degree Celsius (C) at 25°C. The Model 2052 is designed to use a cell with a constant of between 9 and 11. Self Check (Cell constant adjust) span is from 40% to 110% of nominal to allow cell constant correction and TDS scale factors to be easily set. The Cell drive is a low amplitude sine wave, rectification is synchronous.
