CHEMICAL LABORATORY
Our chemical laboratory is equipped to carry out daily controls of the most necessary analyses and not depend on external laboratories. In this way, the baths are permanently monitored and within specification. For this task, the laboratory has the following measurement equipment:

pH-meter
pH is one of the parameters that is analysed the most since it plays a very important role in other parameters such as salts solubility, reaction speed or electrodeposition speed.

Ionometer
The ionometer is an instrument used for the specific determination of an ion by means of ion selective electrodes (ISE). Elhco has an ISE for the measurement of chlorides and fluorides.

Conductivity meter
Purity of and its quality is mainly determined by conductivity, which provides a direct measure of all dissolved ions. Conductivity measurement is crucial for bath formulation and washing waters.

Burettes
The so-called automatic titration burettes are basic tools for titrations. With this technique, multiple analyses can be carried out, such as the determination of the alkalinity/acidity of a bath, metal content, and reductant content, among others.

Rectifier
It is used in Hull cell testing to analyse the main parameters of the electrolytic baths as well as the deposition speed. Then, optimisations of the working parameters can be made to obtain the best quality.

Salt spray chamber
Elhco has a 1000-litre salt spray chamber to carry out accelerated corrosion tests using neutral salt spray in accordance with ISO 9227 and ASTM B117 specifications.

Balances
Balances with different precisions depending on the use: highly precise analytical balances for analyte quantitative analysis and granatary balances for the formation of baths and qualitative level analysis.

Spectrophotometer UV-Vis
Our visible spectrum benchtop spectrophotometer (320 – 1100 nm) allows quick and accurate measurement of a wide range of ions in aqueous medium.

Karl Fischer Titrator
This equipment is used for determining the water content in organic reagents, according to ISO 760 standard.

Tensiometer
The force tensiometer is an instrument for measuring surface and interfacial tension using the ring tear method. It performs quick, simple, and accurate measurements of surfactant solutions and solvents.

Automatic titrator
The equipment is suitable for conventional potentiometric titration applications, facilitating the quantitative determination of a wide range of analytes with high accuracy, reproducibility, and speed of analysis.
METALLOGRAPHIC LABORATORY
The metallographic laboratory is fully equipped to carry out measurements of the physical properties of the deposited layers for compliance validation of the requirements of the specifications.

Taber rotatory abraser
We have a high-precision rotational abrasimeter, specially designed to perform accelerated wear tests on a wide range of materials. This test is performed at Elhco according to ASTM D4060-19.

Electrical conductivity meter
This equipment allows us to quickly and non-destructively determine the electrical conductivity of aluminum and its alloys. Additionally, the results obtained can be correlated with certain mechanical properties of the alloy, such as hardness. This test is performed according to AITM 6-6004.

Immersion tank for liquid resistance
This equipment is used to determine the resistance of paint systems to the action of liquids, using the water immersion method at controlled temperature, according to ISO 2812/2.

Anodising thickness detector
This equipment allows for the rapid, in-situ determination of whether an aluminum part has been properly anodised, in accordance with Airbus AITM 6-9004. The detector is based on the difference in electrical resistance between anodised and non-anodised surfaces, as the oxide layer formed during anodising exhibits significantly higher electrical resistance.
