Digital direct reading conductivity meter is designed for measuring the specific conductivity of solution using a conductivity cell. It enables to measure the conductivity without manual balancing and specific conductivity is read directly on a digital display. This instrument incorporates integrated circuit and thus the power consumption is kept very low.

Frequency SourceIn built automatically selected.
Selectable RangeConductivity: 0-20 µs / cm , 200 µs / cm, 2 ms / cm & 200 ms/cms TDS : 0-20 ppm, 200 ppm, 2 ppt & 200 ppt
Measuring Accuracy+ 1% of F.S. in all ranges +/- 1 count @ 20 ° C.
Indication3.5 digit LED
CalibrationSingle point manually
DecimalAutomatic selection
Conductivity Cellapprox 1.0 cell constant with plastic protective cover (optional 0.1 cell)

Standard AccessoriesConductivity cell, stand rod clamp dust cover & manual

Automation TypeAutomatic


Waste Water, Determination of Biological Activity, Waste Water Treatment Plants, Analytical Laboratories, Scientific & Research.

  • Direct sample selection
  • Accurate and direct display of BOD values in mg/l
  • User-friendly handling
  • User-selectable measuring period from 1 to 28 days (BOD5, BOD7, OECD…)
  • Storage of all values
  • Measuring ranges from 0-40 mg/l to 0-4000 mg/l BOD, sample volume related
  • Auto start function after temperature equalisation
  • Mercury-free, environmentally-friendly
  • Inductive stirring system with automatic re-centering of stirring rods
  • Interface RS 232



The sensor system is a 6 sample system that allows precise measurements of BOD based on the manometric principle. Manometric respirometers relate oxygen uptake to the change in pressure caused by oxygen consumption while maintain-ing a constant volume. Thanks to the modern integral pressure sensors, it is no longer necessary to use mercury for pressure measurements.

Biochemical Oxygen Demand (BOD)

BOD – biochemical oxygen demand – is an expression for the quantity of oxygen required for biological degradation of organic matter in a waste water sample. BOD measurement is therefore used as a basis for the detection of biologically degradable organic matter in water. The difference between BOD and chemical oxygen demand (COD) is that COD additionally registers biologically non-degradable organic matter. BOD measurement is therefore an important measurement of the effects of domestic and industrial waste water on sewage plants and outflow points.
