The CON 550 benchtop conductivity meter features a microprocessor chip which provides automatic calibration, automatic temperature compensation, data storage, parameter setup, and Max/Min reading display. The meter reads 0 to 200 mS/cm across four ranges and the four-point conductivity calibration, with automatic solution recognition, makes for easy calibration. The advanced digital processing technology improves meter response time and measuring accuracy. A stable reading display icon appears when the measuring value is stable.

A conductivity electrode with temperature sensor measures conductivity and temperature simultaneously and allows for automatic temperature compensation. The compact meter includes a detachable electrode holder and three bottles of conductivity calibration solution. It has a dustproof and spillproof rating of IP54. Connectors are protected by silicone seal caps.
