Product Information

Extech ® ExStik II pH/Conductivity Kit

Get on-the-spot soil analysis quickly and easily. Kit includes everything you need to measure five parameters: conductivity, TDS, salinity, pH and temperature in nine units of measure (µS/cm, mS/cm, ppt, ppm, mg/L, g/L, pH, ºC or ºF). Meter stores up to 25 readings and has an analog bar graph that indicates trends. “Renew” feature alerts you when the electrode needs to be replaced. Auto power-off and low-battery indicator. Waterproof to IP57. Meter measures 1.4" x 7.3" x 1.6" overall. Weighs 3.8 oz. Includes weighted base. Imported.

Kit Includes:

  • (1) Carrying Case
  • (4) 3-Volt CR-2032 batteries
  • (1) 48" neck strap
  • (1) Conductivity calibration standards (84µS/cm, 1413 µS/cm and 12880µS/cm)
  • (4) pH buffer pouches (1, 4, 7 and 10 pH plus rinse solution)
  • (3) Sample cups with caps
