SM301/SM302/SM401/SM402Portable Conductivity & TDS Meters

SM301, SM302, SM401 and SM402 are conductivity and TDS Portable Meters, with Automatic Temperature Compensation, and are ideal for the educational and agricultural markets.  Soil conductivity is checked before fertilizer application to pinpoint field needs and after fertilization to establish its effectiveness. The testing of EC provides all agricultural operation with a method to optimize chemical applications and minimize operational cost.  These instruments have been designed to meet the Grower's need for equipment suited to the aggressive environments found in agricultural and hydroponics applications.  Choose your portable EC & TDS meter according to the proper EC/TDS ranges for your application:

• SM301: 0 to 1990 μS/cm with a 10 μS/cm resolution;

• SM302: 0.0 to 10.0 mS/cm with a 0.1 mS/cm resolution;

• SM401: 0 to 1990 mg/L (ppm) with a 10 mg/L resolution;

• SM402: 0.0 to 10.0 g/L (ppt) with a 0.1 g/L resolution.

Each meter is supplied complete with Conductivity/TDS probe with 1 meter cable and calibration solution.
