Mi490 Photometer for the determination of PEROXIDE VALUE in the process of oil making by Milwaukee

Mi490 is a user-friendly photometer for monitoring peroxide value in the process of oil making. This instrument will give you direct readings, with a range of 0.0 to 25.0 meq O2/Kg.

The measurement of the oil's chemical degradation is the peroxide value, which measures the degree to which the oil is oxidized. Rancidification is the decomposition of fats and other lipids by hydrolysis and/or oxidation. Hydrolysis will split fatty acid chains away from the glycerol backbone in glycerides. These free fatty acids can then undergo further auto-oxidation. Oxidation primarily occurs with unsaturated fats by a free radical-mediated process.

One of the most widely used tests for oxidative rancidity, peroxide value is a measure of the concentration of peroxides and hydroperoxides formed in the initial stages of lipid oxidation. Milliequivalents of peroxide per kg of fat are measured by titration with iodide ion.

Peroxide values are not static and care must be taken in handling and testing samples. It is difficult to provide a specific guideline relating peroxide value to rancidity. High peroxide values are a definite indication of a rancid fat, but moderate values may be the result of depletion of peroxides after reaching high concentrations.

Mi414 Chloride Professional Photometer by Milwaukee

Chlorides are used by the water treatment professional to determine cycles of concentration in low pressure boilers and cooling systems. It is essential to monitor chloride concentrations in boiler systems to prevent metal parts being damaged. In high levels, chloride can corrode stainless steel.

Milwaukee offers MI414 microprocessor-based instrument with greater resolution, better accuracy and immediate results for measuring chloride (0.00 to 20.00 mg/L).

MW10 Free Chlorine Mini-Colorimeter by Milwaukee

The revolutionary new range of Milwaukee handy photometers are compact and easy to use, have a modern design, and measure Free Chlorine (MW10); Total Chlorine (MW11); Phosphate (MW12); Iodine (MW13) and Iron (MW14). Their main advantages are the small size, and the real simplicity when doing measurements on the spot. Within a few minutes you can get the required result on the LCD and the instrument directly displays the concentration of the specific component in ppm. The meter automatically turns off after 2 minutes in order to save the battery.They work exactly the same way as the other Milwaukee photometers:

When specific reagents are added, the water sample takes on a degree of coloration that is proportional to the concentration of the parameter being measured. The photometer measures this coloration. When a light beam passes through the coloured sample, energy with a specific wavelength is absorbed by the test substance. The photometer determines the coloration of the sample by measuring the transmission or absorption of light of this wavelength. The photometer then uses a microprocessor to calculate the concentration and displays the result.

The field of application is really wide including agriculture, drinking water analyses, aquariums, swimming pools or fish farms. As a result of this versatility and the affordable price it is undoubtedly worth using these products.

Mi407 Ammonia (Low Range) Professional Photometer by Milwaukee

This user-friendly Colorimeter will give you direct readings in mg/L. Ammonia detection in water treatment systems is particularly important for aquarium owners and fish farm operators.

Ammonia is highly soluble in water and extremely toxic to fish. Fish farm owners must monitor and maintain careful control of ammonia levels to ensure optimum water conditions for their stock.

Milwaukee offers the Mi407 microprocessor-based instrument with greater resolution, better accuracy and immediate results for measuring low concentrations of Ammonia (from 0.00 to 3.00 mg/L).

Mi404 Free & Total Chlorine Professional Photometer by Milwaukee

Milwaukee provides a range of chlorine photometers for all applications: swimming pool treatments, household cleaners, dishwasher additives, laundry powders/liquids and cooling water treatment products all contain chlorine as an oxidizing biocide. Drinking water contains residual chlorine to maintain water purity throughout the supply lines.

Milwaukee offers the Mi404, a microprocessor-based instrument with greater resolution, better accuracy and immediate results for measuring free (0.00 to 5.00 mg/L) and total (0.00 to 5.00 mg/L) chlorine.

Mi405 Ammonia (Medium Range) Professional Photometer by Milwaukee

This user-friendly Colorimeter will give you direct readings in mg/L.

Ammonia detection in water treatment systems is particularly important for aquarium owners and fish farm operators.

Ammonia is highly soluble in water and extremely toxic to fish. Fish farm owners must monitor and maintain careful control of ammonia levels to ensure optimum water conditions for their stock.

Milwaukee offers the Mi405 Photometer with a range of 0.00 to 9.99 mg/L, for medium concentrations.

Mi406 Free Chlorine Professional Photometer by Milwaukee

Milwaukee provides a range of chlorine photometers for all applications: swimming pool treatments, household cleaners, dishwasher additives, laundry powders/liquids and cooling water treatment products all contain chlorine as an oxidizing biocide. Drinking water contains residual chlorine to maintain water purity throughout the supply lines.

Milwaukee offer the Mi406 microprocessor-based instrument with greater resolution, better accuracy and immediate results, for measuring free chlorine (0.00 to 5.00 mg/L).

Mi408 Iron (High Range) Professional Photometer by Milwaukee

This user-friendly Colorimeter will give you direct readings in mg/L. Iron is naturally present in water supplies and its presence in both potable and industrial applications is regarded as objectionable.

Milwaukee offers Mi408 microprocessor-based instrument with greater resolution, better accuracy and immediate results for measuring high concentrations of Iron (from 0.00 to 5.00 mg/L).

Mi411 Free & Total Chlorine and pH Professional Photometer by Milwaukee

This latest laboratory grade Microprocessor photometer has an excellent repeatability and is ideal for field measurements.

Chlorine is the most commonly used water disinfectant. Applications vary from treatment of drinking water and wastewater to pool and spa sanitization and food processing to sterilization.

Martini Instruments has developed the Mi411, a portable microprocessor based instrument to measure three critical parameters to ensure good water quality: pH, free chlorine and total chlorine.

This instrument provides greater resolution, better accuracy and immediate results.

Mi411 is supplied in a hard carrying case including 2 cuvets, reagents for 100 tests, wiping tissue and instruction manual.

Mi412 Phosphate (Low Range) Professional Photometer by Milwaukee

This user-friendly Colorimeters will give you direct readings in mg/L. Phosphates are present in natural waters and at concentrations typically found, do not pose any specific health threats to humans.

However, excessive contamination of water courses from agricultural fertilizer run off or wastewater/effluent discharge can promote excessive algae or plant growth.

Milwaukee offers Mi412 with range 0.00 to 2.50 mg/L.

Mi413 Free & Total Chlorine (High Range) Professional Photometer by Milwaukee

Milwaukee provides a range of chlorine photometers for all applications: swimming pool treatments, household cleaners, dishwasher additives, laundry powders/liquids and cooling water treatment products all contain chlorine as an oxidizing biocide. Drinking water contains residual chlorine to maintain water purity throughout the supply lines.

Milwaukee offer the Mi413 microprocessor-based instrument with greater resolution, better accuracy and immediate results, for measuring free (0.00 to 10.00 mg/L) and total (0.00 to 10.00 mg/L) chlorine.
