WTW Portable Multi-Parameter Meter

• Automatic sensor recognition
• Automatic calibration of all sensors
• Automatic temperature compensation
• Stability indicator for high reproducibility in results
• Time controlled measurements
• 800 point datalogging
• RS232 interface
• GLP functions
• Waterproof

Simultaneous connection of a pH/mV electrode and an oxygen sensor or conductivity cell (4 cell) allows up to three parameters (including temperature) to be measured at the same time. This rugged waterproof meter is ideal for use in the field, laboratory or production sites with its large multi-function display, impact-resistant anti-static ABS plastic housing and silicone keypad for simple and comfortable operation. Each datalogging point can store 3 measured values plus date, time and individual identification number. Time controlled measurements can be taken over periods of up to 5 days, and time-controlled data output can be set at 8 fixed intervals ranging from 5 seconds to 60 minutes. The meter meets GLP guidelines with the following calibration protocol: storing date and time of current calibration, date and time of last calibration, standard solutions used, and probe evaluation. The calibration data can then be printed for future reference. Dimensions: 172 x 80 x 37 mm. Battery or AC operated. 120 volt. ULC Approved. Warranty: 3 years.
