Model 2053 Digital Conductivity Meter

Model 2053 Digital Conductivity Meter
The Model 2053 digital conductivity meter is a portable battery operated instrument, which will measure four ranges of conductivity from 20 µS (micro Siemens) to 20 mS (milli Siemens) full scale. It features three modes of operation, two for the measurement of solution conductivity in A.T.C. "On" or A.T.C. "Off" and one for Self Check. The Self Check function allows for verification of proper operation and the ability to adjust for cell constant variations. The conductivity measurement data is displayed on a 3½ digit Liquid Crystal Display (LCD) with floating decimal.

The Function switch selects Power Off, Automatic Temperature Compensation (A.T.C.) On, Off or Self Check. The A.T.C. is set at 2% per degree C (Celsius) at 25°C with reference at 25°C. The Model 2053 is designed to use a cell with a constant of between 9 and 11.

Model 2053 is an economical, dependable and easy to use basic conductivity meter designed for use in the field or laboratory. An optional Lab Stand with Cell Holder is available for bench top use. Made in USA.
