Photometers

Photometers for precise chemical analysis of liquids

Photometers are advanced measuring instruments used to analyze solutions by measuring the intensity of light passing through a sample. Using the Lambert-Beer law, they allow for precise monitoring of processes such as crystallization, filtration or fermentation. These devices are irreplaceable in pharmacy, biochemistry and environmental protection.

Offering a number of functionalities such as:

• precise determination of the concentration of substances,
• use of transmission and reflection phenomena,
• simultaneous testing of many parameters,
• full integration with LIMS systems,
• Compliant with stringent GLP standards

In laboratories, we most often find spectrophotometers and colorimeters, which usually give results in milligrams per liter. Professional systems play a key role in modern chromatography, ensuring the highest precision of analyses. Importantly, despite the high degree of complexity of advanced models, basic equipment for simple measurements can be purchased at an affordable price.

MD 100, MD 110 and MD 200 photometers for water analysis

The Lovibond MD series are advanced photometers for water analysis that combine measurement precision with exceptional mobility.  The MD 100 features a  lightweight, ergonomic design that's ideal for the field.

FP Flame Photometers for Alkali Metal Determination

FP Series Devices Krüss brands use spectral analysis to determine alkali metals. The equipment integrates with control systems by:

• Ethernet connector,
• USB port,
• RS-232 interface,
• PROFIBUS DP protocol,
• analog output.

Photometers monitor free and total chlorine, which is crucial for water disinfection. This ensures safety in water supply and swimming pools, where strict standards apply. In wastewater analysis, it is essential to measure the concentration of ammonia, iron and phosphates. Sensitive optics guarantee repeatability and control of environmental parameters.

Optics based on interference filters allow you to assess the color of light.

The Bluetooth module sends data to the software, which improves reporting.

Photometers for the determination of free and total chlorine

Milwaukee's precision photometers allow you to professionally determine free and total chlorine using colorimetry. Thanks to DPD tablets and dedicated glass cuvettes, the devices guarantee high repeatability of results with a measurement error of only ±0.06 mg/L. These solutions are perfect both in the field and in advanced laboratory work.

These devices offer comprehensive analytical capabilities for water quality control. Thanks to them, it is possible to:

• measurement of bound chlorine and chlorine dioxide concentration,
• analysis of ammonia, iron and phosphate content,
• pH test with an accuracy of ±0.1 units,
• use of optical filters that eliminate interference,
• data transfer via Bluetooth.

Milwaukee kits provide a reliable alternative to traditional strip testing. The reliability of measurements is supported by specialized calibration solutions and accessories such as micropipettes or mini-centrifuges. The system is complemented by high-quality reagents that ensure reliable and precise control of key water parameters.

Photometers for the determination of ammonia, iron and phosphate

Milwaukee photometers are advanced devices that go beyond standard chlorine testing. With high precision, they analyze environmental and industrial parameters. These devices monitor:

• ammonia concentration,
• iron content,
• phosphate levels,
• the presence of nitrates,
• chromium concentration.

This equipment also supports medical diagnostics and PROCT testing, examining, among other things:

• lactic acid,
• cholesterol,
• glucose,
• haemoglobin,
• creatinine,
• cardiac markers.

Optics with interference filters ensure measurement stability and control of the redox potential. The Bluetooth module transmits data directly to the LIMS systems, which effectively eliminates human error and significantly speeds up the reporting of results.

Bluetooth function and precise interference filters

At the heart of modern photometers are advanced optics that effectively eliminate unnecessary interference. This design allows for extremely precise wavelength selection, guaranteeing the highest quality of measurements in all conditions.

Modern measuring devices are distinguished by the following features:

• energy-saving LEDs,
• efficient xenon lamps,
• precise interference filters,
• sensitive silicon photodiode,
• Bluetooth wireless connectivity,
• specialized calibration filters.

Working in the field becomes much more convenient thanks to wireless technology. Models such as the MD 110 or PM 600 pair with the AquaLX app in no time, sending the results directly to your smartphone or tablet. This solution not only speeds up the analysis, but above all excludes human errors when manually recording data. The professional standard is evidenced by excellent repeatability and a homogeneous light beam, which makes each test fully reliable and meets strict technical standards.
