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 industrial 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 measuring instruments from SCHOTT Instruments. These instruments are setting new standards for electrochemical measurement.
ph measuring instrument 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 detection 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.
Includes built-in NiMH rechargeable accumulator for up to 1,000 hours of continuous measurements and appropriate line adaptor. |

HI 2300 performs EC, TDS (Total Dissolved Solids), percentage of NaCl and temperature measurements. The auto-ranging feature for EC and TDS measurements automatically sets the resolution suitable to the tested sample.
All measurements can be temperature compensated at 20 or 25°C and the compensation coefficient is selectable by the user. The automatic temperature compensation can also be disabled for measuring the actual conductivity value. The stability indicator on the LCD ensures accuracy.
Conductivity readings are performed by applying an alternate current to the 4-ring probe which creates a variable voltage directy proportional to conductivity.
The GLP feature allows users to store and recall data about system status.

Model HPM 4/6 portable vacuum meters are compact, hand-held, digital display, battery operated control units. When combined with the Hastings Instruments rugged thermopile sensors, they become vacuum instruments designed for portability and ease of use in applications where AC power is not readily available.
The lightweight control units operate with a standard 9 volt battery, and are available for display in units of Torr or mbar. Additionally, they can be calibrated to an individual sensor or set for average sensor output to test many different sensors of the same type. They are switchable to offer display for both the DV-6 (0.001 to 1 Torr) and the DV-4 (0.01 to 20 Torr) sensors without re-calibrating. These sensors are rugged, noble metal sensors which are resistant to corrosion and can be ordered with a variety of system connections to meet your system's requirements such as VCR(R), KF 16, KF 25, Glass, MiniConflat™, etc.
