SD 335 Multi — Multiparameter Meter with Data Logger
- Simultaneous multi-parameter measurement
- The SD 335 Multi uses galvanically isolated measuring inputs to simultaneously determine pH, temperature and a second parameter — conductivity/TDS/salinity (Set 1), dissolved oxygen (Set 2), or all three together (Set 3). All values are displayed at once on the backlit graphical LCD.
- Built-in data logger with time stamp and location ID
- Measurement data can be recorded manually by keystroke or automatically at a user-adjustable cyclic time interval. Each data record includes a time stamp and location ID. Data is transferred via Micro-USB to a computer in CSV format — no additional software required.
- Robust waterproof design — IP67
- The SD 335 features a protective armoured housing with two electrode holders that guarantees safe operation in extreme field conditions. The fold-out stand on the rear doubles as a hanger or belt clip. NiMH rechargeable batteries are included and charged via Micro-US
- Intuitive operation in 7 languages
- The graphic LCD display with user-friendly guided menus is available in 7 languages, making the SD 335 equally suited to international fieldwork and laboratory use. Self-diagnosis of sensors and battery status display are built in.
- Supplied complete and ready to use
- Each set is supplied in a carry case with instrument, appropriate electrodes and sensors, pH buffer set (4.01/7.00/10.01), storage solution, conductivity standard (Set 1 & 3), electrolyte and calibration bottle with sponge (Set 2 & 3), NiMH battery pack, Micro-USB cable and instruction manual.
