A Single Source for Water Testing Equipment
The Lovibond® range offers users a single source for equipment for the chemical analysis of water in all environments - potable and washing water, surface, ground and raw water, waste water and effluents, boiler and cooling water and swimming pools.
In particular the Lovibond® range presents a simple and flexible approach to routine water analysis that gives reliable results in both laboratory and field testing. It even includes the Vario range of reagents in the form of powder packs, which can be used in other manufacturers’ photometers.
Ongoing Product Innovation and Development
We are committed to the ongoing develop-ment and improvement of our testing equipment and reagents. This commitment is demonstrated by the latest innovations of Tintometer:
The SD 400 Oxi L for oxygen measurement with the Luminescence-Technology and the new photometers MD 610 & PM 630 with Bluetooth® interface.
Both units based on a long experience in development of water testing systems and impress by origin Lovibond® quality.
Production Control and Assurance
All Lovibond® instruments, reagents and accessories are manufactured under our control, employing modern technology and QA procedures. Tintometer GmbH has been certified DIN ISO 9001 since more than 20 years.
MINIKIT - LOVIBOND
Easy operation and exact reagent dosing
Foil-wrapped Lovibond® tablet reagents with a minimum guaranteed shelf life of 5 years
The MINIKITs are designed for rapid water testing. Most MINIKITS are based on titrimetric methods.
Tablet count method
In the tablet count method, the liquid titration solution and indicator are replaced by Lovibond® tablet reagents. A specific number of tablets is added to a defined sample volume until a chemically induced colour change takes place. The concentration of the parameter being measured is calculated from the number of tablets required. The measuring range can be expanded by varying the sample volume.
A Yes/No test tells the user whether a specific ingredient is present in the water and/or if its concentration is higher or lower than a defined level.
A two-section calibrated test tube is filled with the water sample and a reagent tablet added.The reagent creates a level of turbidity that is proportional to the concentration of the parameter being measured. The inner tube, which has a black dot on its base, is lowered until the dot is obscured by the turbidity. The result is read off from the water level in the inner tube.
The speed test is based on reverse titration. After adding a reagent tablet to a calibrated test tube, the water sample is added slowly until the colour of the solution changes (e.g. from red to blue). The user can then obtain the result from the liquid level.
ARSENIC TEST KIT (HIGHLY SENSITIVE)
The arsenic test is due to its high sensitivity suitable for the determination of arsenic in drinking water.

Continuous colour scale
The Lovibond® CHECKIT® Comparator is a compact and handy colorimetric unit which is suitable both for mobile and stationary
analysis work. Supplied with a generous number of different colour scales, it provides the basis for a comprehensive, easy-to-use colorimetric analysis system.
The CHECKIT® Comparator D55 enables the use of large path lengths. The mirror optics makes use of the view through the entire length of the cell.
Each CHECKIT® Disc contains a continuous colour scale which makes it possible to achieve an exact colour match between the colour standard and the sample. These CHECKIT® Discs are specially manufactured in selected materials to remain
colour-stability over a long period and guarantee reliable, reproducible measurement results. Instruction manuals explaining the various stages of analysis in simple, straightforward terms, are supplied with each CHECKIT® Disc.
MD 100 Photometer - Lovibond
Precise Water Analysis in High-Quality Design
The MD 100 uses high quality interference filters with long-life LEDs as a light source without any moving parts in a transparent sample chamber.
The units supply accurate, reproducible results very quickly. Other major advantages include ease of operation, ergonomic design, compact dimensions and safe handling.
The calibration and software-based adjustment options mean that the MD 100 is also suitable
for use as a testing instrument.
The tests are conducted using either Lovibond® tablet reagents with long-term stability and a
guaranteed minimum 5 or 10 year shelf life, VARIO powder reagents or using liquid reagents

*) as defined in IP 68, 1 hour at 0.1 meter
Scroll Memory (SM)
To avoid unnecessary scrolling for the required test method, the instrument memorizes the last method used before switching off the instrument. When the instrument is switched on again, the scroll list comes up with the last used test method first.
Zero Setting (OTZ)
For certain versions of the instrument it is not necessary to zero the instrument each time.
The zero setting is held in memory until the device is turned off. (One Time Zero - OTZ). The zero
setting can be confirmed whenever it is required.
Manufacturers Test Certificate M
Besides the “Certificate of Compliance” which is supplied with the MD 100, manufacturers test certificates M are available at cost on request. Manufacturers test certificates M are individually
supplied per instrument and per method.
The manufacturers test certificate M has to be ordered together with the new instrument and cannot be delivered at a later stage. N.I.S.T Traceability The instrument has a factory calibration, which is related to international standards which are not N.I.S.T traceable. The instrument may be calibrated by the user in a "user calibration mode" with N.I.S.T traceable standards.

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.
Manometric, respirometric BOD measurement using the Lovibond® BD 600
The Lovibond® sensor system BD 600 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 maintaining a constant volume. Thanks to the modern integral pressure sensors, it is no longer necessary to use mercury for pressure measurements.
BD 600 Principle
Respirometric methods provide direct measurements of the oxygen consumed by microorganisms from an air or oxygen-enriched environment in a closed vessel under conditions of constant temperature and agitation. Carbon dioxide produced metabolically by the bacteria is chemically bound by the potassium hydroxide solution contained in the seal cup in the bottle.
The result is a pressure drop in the system, which is directly proportional to the BOD value and is measured by the BOD sensor. The BOD level is then displayed directly in mg/l.
The BOD values are stored automatically in the sensor memory in regulary intervals and can be called up on the large-format display at any time without the need for time-consuming conversion using factors. This means that test series that end on a Sunday can be evaluated during the following week without any problem. Measurement series can be stored on USB stick/SD card or transferred via USB cable to evaluate the datas on a computer.
The measurement period is user-selectable between 1 and 28 days to suit the application.While short measurement periods are useful for scientific applications, standard BOD measurements typically extend over a period of 5 days – and manometric determination of OECD, for example, generally takes place over a period of 28 days.
Evaluation of measurements
The BD 600 measuring system records a measurement once every hour, independent of the length of the measuring period. This way the quality of the series of measurement can be evaluated in an early stage. Current values and stored values may be called up at any time. Stored value can be displayed numerically or graphically. The table/ graph on the left illustrates an example of BOD5 evaluation. The development of BOD over a period of five days is easily seen.
