Continued on next page 936 Conductivity Meters webcode WWSE2014 Conductivity Meter SD 325 Con, Lovibond® The portable instrument with data logger is ideal for determining electrical conductivity in aqueous media. With a simple keystroke, further parameters such as TDS, salinity or resistance can be selected and conveniently read off. With the SD 325 Con, both low (< 200 µS/cm) and very high conductivities (< 1000 mS/cm) can be detected with highest precision, but the choice of the right measuring cell is decisive. The simplified operator guidance with all relevant configuration options facilitates the use of the measuring instrument in all areas of water analysis. Measurement data including time stamp and measuring location ID can be recorded conveniently with the data logger function either automatically at a fixed time interval (10000 data sets) or manually at the push of a button (1000 data sets). • Automatic recognition of conductivity standards • Alarm function with adjustable limit values • Auto hold function • Selectable reference temperature (20°C / 25°C) • Automatic temperature compensation • Battery status indicator • Low power consumption = long battery life • Data transfer and evaluation via software possible Scope of delivery in carrying case: instrument in protective armouring, conductivity measuring cell, conductivity standards (set 1 / set 2), electrode holder (set 1/ set 3), flow cell for ultrapure water (set 3), 2 × AAA batteries and user manual Technical data: Measuring principle: Conductometry Measuring range (depending on conductivity cell): Conductivity: 0.000 – 1000 mS/cm Resistance: 0.000 – 50.0 MΩ*cm TDS: 0.000 – 5000 mg/l Salinity: 0.0 – 70.0 PSU Temperature: -5.0 – 100.0°C Display: Backlit LCD display Power supply: 2 × AAA-batteries, interface cable with USB connection Data logger: Manual logger: 1000 data sets (single value by keystroke) Auto. logger: 10000 data sets (cyclic, time interval: 1 – 3600 s) Auto – OFF: yes Dimensions: 164 × 100 × 37 mm Weight: 302 g (incl. batteries and protective armouring) Protection class: IP 67 Conformity: CE, RoHS, WEEE Article Order No. SD 325 Con (set 1) 10 77 13251 Conductivity electrode LC 12 (4-pole graphite, < 200 mS/cm) multipurpose operation SD 325 Con (set 2) 10 77 13252 Conductivity electrode LC 16 (4-pole graphite, < 1000 mS/cm) high conductivities SD 325 Con (set 3) 10 77 13253 Conductivity electrode LC 10 (2-pole stainless steel, < 200 µS/ cm) ultrapure water Portable Hand-held Meter SensoDirect 150, Lovibond® The SD 150 Multi-Parameter handheld instrument is ideal for the sequential determination of pH, Redox/ORP, conductivity, TDS and dissolved oxygen (O2) and combines the applications of several instruments in one portable device. The protective armouring with builtin holder not only provides a secure grip, but also protects both the sensor and the meter from damage caused by falling. Functions such as automatic temperature compensation or automatic recognition of standard solutions greatly simplify measurement and calibration procedures. The large, clearly arranged LCD display shows the measurement parameter and the temperature simultaneously, thus facilitating temperature-dependent documentation. • All in one • Automatic recognition of standard solutions • Protective armouring with in-built electrode holder • Large LCD-Display • Automatic temperature compensation Scope of delivery in carrying case: instrument in protective armouring incl. electrode holder, pH electrode type 226, temperature sensor Pt1000, pH buffer, operating manual, further sensors according to set Measuring Systems Electrochemistry
