For high accuracy testing of pH, EC/TDS and Temperature
No more switching between meters for your routine measurements. The waterproof Combo (it even floats) has a large easy-to-read, dual-level LCD and automatic shut-off. The pH and EC/TDS readings are automatically compensated for the effects of temperature (ATC). This technologically advanced tester has a replacement pH electrode cartridge with an extendable cloth junction as well as an EC/TDS graphic electrode that resists contamination by salts and other substances giving these meters a greatly extended life. Your tester no longer needs to thrown away when the pH sensor is exhausted.
The gauge comes complete with batteries, calibration certificate and instructions.
