Biochemical oxygen demand BOD determination is still one of the most important parameters in water resource management. It can be used to evaluate the impact of biodegradable substances in waters and waster water. With its OxiTop® systems, WTW offers a unique, modular and mercury-free instrument system. It is not only suitable for BOD determination, but also for measuring biodegradability and depletion.
In the course of growing environmental consciousness, microbiological degradability tests have become increasingly important. These can be, for example, soil surveys from waste sites or environmental impact surveys for new chemical substances. The necessary respiration measurements for anaerobic or aerobic degradation can be easily carried out using the OxiTop®-C systems with excellent analysis. WTW offers a wide range of application specific packages with appropriate sample vessels.
The advantages of OxiTop® and OxiTop® Control: simple operation, improved controllability and non-toxicity, and measuring ranges of up to 400 000 mg/l BOD (with OxiTop® Control OC 110). As the measured pressure is automatically converted the values can be directly read as mg/l BOD

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.

WTW’s well-known „3xxi“ family of portable measuring instruments is available in four differrent product ranges:
1) For standard applications which do not require automated documentation nor extended sensor options, the 315i series is adequate. The customer can choose an instrument for either of the main standard electrochemical parameters pH/mV, DO and conductivity.
2) If special sensors (particularly such for conductivity measurement) or additional calibration procedures are to be employed, the 330i series instruments are a good choice.
3) Anybody seeking flexibility regarding the employment of sensors plus comfortable and reliable data transfer, will opt for the 340i series. This range includes not only single parameter instruments for pH, DO and conductivity, but as well combination instruments for pH/cond, pH/DO, and multiparameter (pH/DO/cond).
4) The multiparameter instrument Multi 350i takes in an outstanding position within the WTW range. By means of special sensors, this instrument can measure and store up to 3 parameters simultaneously.

pH, mV, ISE, Oxygen, Conductivity: The new Multi 350i can measure all of these parameters. If desired, pH, oxygen, conductivity and temperature can be measured simultaneously: In the Laboratory using the combined conductivity/oxygen sensor ConOx, in the field with the multiparameter probe MPP 350. All current WTW pH, combination ISE’s, oxygen and conductivity sensors can be additionally connected.
High resolution, high precision, simple, menu-driven operation. Even in poor lighting conditions the backlit graphics display provides clearly readable values. A datalogger, memory for 1,800 data sets and a real-time clock support GLP requirements.

Thermo Scientific's series of portable gas detection instruments use several types of detectors, including catalytic oxidation for hydrocarbon detection and electrochemical for toxic gases and oxygen. It should be noted that all detectors can experience extreme loss of sensitivity if exposed to certain materials (for instance, silicone for the catalytic detector). The instrument should always be checked if exposed to extreme concentration, suspected poisons, or contaminants.

The compact, rugged Thermo Scientific SGD-O is the most reliable non-contacting density gauge for monitoring fluid density, including PPG, PPA and SGU, in the oilfield during fracturing and cementing. Capable of enduring high shock and vibration yet lightweight, this advanced device features rapid response and high accuracy to improve consistency, safety and overall performance. Engineered to withstand the extreme moisture and high humidity of oilfield environments, it rapidly indicates variations in slurry density and proppant concentration during fracturing and cementing operations. The SGD-O is comprised of three components: the source and detector work together to measure the fluid density while the remotely located electronic transmitter provides a clear digital display of the measurement. This advanced gauge measures through any pipe thickness, with the detector providing response in three to five seconds and accuracy of ±0.1 pounds per gallon. The transmitter can be mounted up to 100 feet away from the gauge to ensure worker safety. It can be powered by a readily available 12 or 24 volt power supply and features quick disconnect connectors for cable and transmitters. The SGD-O is also easy-to-install and use and has minimal maintenance requirements.

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.

DO stands for Dissolved Oxygen, which is the measure of amount of gaseous oxygen dissolved in a solution. In theory, the amount of DO in a solution is dependent on 3 factors, namely temperature, salinity and atmospheric pressure. The measurement of DO requires a special DO electrode that is made up of an anode, a cathode, electrolyte solution and a gas permeable membrane.
