Combo pH / EC / TDS / Temperature Meters

Two pocket size pH testers offering high accuracy pH, EC/TDS and temperature measurements all in a single unit. The Combo is waterproof (it even floats), has a large easy-to-read, dual-level LCD display and automatic shut off. pH and EC/TDS readings are automatically compensated for the effects of temperature (ATC). The EC/TDS conversion factor is user selectable as well as the temperature compensation coefficient (ß).

These technologically advanced testers have a replaceable pH electrode cartridge with an extendable cloth junction as well as an EC/TDS graphite electrode that resists contamination by salts and other substances. Supplied with protective cap, electrode removal tool, batteries and instructions.

The buffer calibration kit (which is not included but is required for initial and routine calibration) has 10 sachets, 5 each pH 4.01 & pH 7.0.
