The total TDS is a mass estimate and is dependent on the mix of chemical species as well as the concentration while conductivity is only dependent on the concentration of chemical species. Some applications require the measurement of Total Dissolved Solids (TDS) in mg/L, parts per million (ppm) or parts per thousand (ppt). The TDS concentration can be obtained by multiplying the conductivity
value with a factor which is empirically determined. Eutech offers meters that allow the direct reading
of TDS values. These include the TDSTestr™ series, EcoScan TDS 6, CyberScan Standard Portables CON 11, CON 110 and Waterproof Portable CON 410. Bench meters for advanced level laboratory research are the CyberScan CON 510, CON 1500 and colour touchscreen research-grade CON 6000. |

Precise measurement is a product of the optimal interaction between electrode, calibration and meter. The obvious next step for us has been to develop meters to perfectly match our electrodes and buffer solutions. The result: The new Lab series of pH and conductivity meters from SCHOTT Instruments. These instruments are setting new standards for electrochemical measurement.
pH-meter Lab 850
The Lab 850, our “starter” model in the new series, comes with the advanced measuring algorithm specially adapted to SCHOTT Instruments’ electrodes. The result is a calibration and measurement in usual precision – but in a much shorter time!
pH-meter Lab 860 and conductivity meter Lab 960
Whether conventional via RS232 or modern via USB slave – both interfaces to the PC are integrated in the Lab 860 and Lab 960. No adapter is required.
pH–meter Lab 870 and conductivity meter Lab 970
The quality controller’s dream: A measuring instrument automatically recognizes the electrode! The new sensors with unique identification send their specific data to the measuring instrument … wireless! Thus the Lab 870 and Lab 970 always use the correct calibration for the identified sensor and help you to avoid errors in measurement. |

HFM 436 Lambda - Heat flow meter
With the HFM 436 Lambda, samples measuring 30 cm x 30 cm or 60 cm x 60 cm and of variable thicknesses ranging from a few millimeters to 10 (20) cm are tested between two heat flux sensors in fixed or adjustable temperature gradients. After a few minutes for the system to reach equilibrium, the built-in PC or external computer determines the thermal conductivity and thermal resistance of the sample.
Automatic plate movement and determination of the sample thickness simplify test preparation.
All test parameters as well as the calibration data are stored in the PC and documented.
Determination of thermal conductivity with the HFM 436 Lambda meets the industry standards ASTM C 518, ISO 8301, JIS A 1412, DIN EN 12939, DIN EN 13163 and DIN EN 12667. |
