Conductivity Meters Product Description

The EC500 Conductivity Meters can measure 5 different parameters including Conductivity, TDS, Salinity, pH, and Temperature using the conductivity meter’s single electrode. With the 5 parameters the conductivity meters offer 9 units of measure including pH, uS/cm, mS/cm, ppm, ppt, mg/L, and g/L, °C, and °F. The conductivity meters display the results on a large LCD screen that supports an Analog bar graph to indicate trends, a RENEW feature to alert you that the pH sensor needs replacement, and a low battery indicator.

The EC500 Conductivity Meters were designed to be easy to use in harsh environments. The conductivity meters are waterproof to the IP67 standard, has enough memory to store up to 25 labeled readings, has an adjustable conductivity to TDS ratio factor that allows for convenient calculation of the TDS value, contains a fixed 0.5 fixed salinity ratio, and supports an automatic power shut off feature. The conductivity meter includes the electrode, protective sensor cap, sample cup with cap, four 1.5V SR44W batteries, and a 48 inch (1.2m) neckstrap.
