SD 320 Con / Lovibond

Waterproof Hand-held Meters for Conductivity, TDS, Salinity, Temperature

Highlights

- Rugged, water resistant (IP 67) designed for field use
- PC interface (USB / serial or analog)
- Automatic buffer detection (SD 300 pH)
- Data logger and alarm function (min./max.)
- Good Laboratory Practice (GLP-features)
- Clear, concise result reading: easy-to-read backlit LCD display
- Automatic temperature compensation
- High resolution (0.001 pH / 0.1 mV) (SD 300 pH)
- Dirt-insensitive up-to-date 4-pole conductivity cell offering highest precision (SD 320 Con)

Applications

- Drinking Water
- Cooling/Boiler Water
- Waste Water
- Pool Water
- Surface Water

Features SD 320 Con

- Min / Max Value Memory highest and lowest measured value is saved
- Auto Hold freeze and display measurement
- Auto Power Off if unused, the meter automatically switches off after a selected period (0 to 120 min, or deactivated)
- Low Battery Display “BAT”
- Automatic temperature compensation As conductivity depends strongly on temperature, each conductivity value is only valid at the corresponding temperature. Therefore the device supports temperature compensation, i.e. referring the conductivity to a reference temperature (selectable: 20 °C or 25 °C).
- Salinity measurement Salinity means the sum of amount of all dissolved salts in water. The unit is g / kg.
- TDS measurement (total dissolved solids) TDS means the mass concentration of dissolved media in a liquid. The unit is mg/l.
