sympHony® pH Meters

Simple 3-Button Operation
Bright LCD Display with Ready Indicator
Automatic or Manual pH Calibration
Three-Year Limited Warranty
Ideally suited for general lab use, environmental field applications, and teaching. These compact pH meters offer easy, three-button operation and a clear, intuitive user interface. A simple set-up menu and icon prompts guide non-technical users through the measurement process. Up to 10 setup parameters and calibrations may be stored and password-protected, making them ideal for multiple users. Additional methods, as well as software updates, may be downloaded via the Web. Meters feature waterproof BNC pH electrode connectors; automatic or manual pH calibration, with 1 to 5 calibration points; automatic buffer recognition of NIST, US, and DIN buffers; advanced self-tests on meter operation with self-diagnostics; 225-point data logging; and a universal power adapter for worldwide operation. Data can be downloaded to printer or computer via the RS-232 connection.
Benchtop meters meet IP54 specifications with protection from water and include an optional USB interface cable. These meters are CE marked, CSA and TÜV certified, and UL listed. The handheld meters meet IP67 specifications, allowing the sensor to be immersed in water to a depth of 1m for 1 hour without any water incursion. Handheld meters also feature USB outputs, an extended-life battery for up to 2000 hours of uninterrupted operation, and are CE marked. Optional sympHony Navigator 21* software ensures regulatory compliance and includes system validation, security and audit trails with time and date stamps, archiving, and record retention and recovery.
