Description
Features:
- High accuracy pH, EC/TDS and temperature measurements
- Waterproof combo has a large easy-to-read, dual-level LCD and automatically shuts-off
- EC/TDS and pH readings automatically compensate for the effects of temperature (ATC)
- Tester has a greatly extended life:
- Replaceable pH electrode cartridge with an extendable cloth junction.
- EC/TDS graphite electrode resists contamination by salts/other substances.
- User can select the EC/TDS conversion factor and the temperature compensation coefficient (ß)
