METAL SAMPLES
Metal Samples specializes in manufacturing products for corrosion monitoring and materials evaluation. Since 1980, Metal Samples has supplied products and services to members of nuclear, medical, aerospace, chemical processing, oil & gas, water treating, and petroleum industries around the world.
Metal Samples offers a full range of corrosion monitoring systems, including access fittings for high-pressure/temperature systems to insert and retrieve probes, chemical injection systems, quills, and nozzles. Corrosion instruments include portable meters, transmitters, and data loggers. Other products include corrosion test coupons, holders, insertion systems, and test racks.
Metal Samples offers a complete line of corrosion monitoring instruments / meters for both electrical resistance (ER) and linear polarization resistance (LPR) probes, and for specialized monitoring.
WHY USE METAL SAMPLES?
The electrochemical technique, commonly referred to as Linear Polarization Resistance, is the only corrosion monitoring method that allows corrosion rates to be measured directly, in real time. Although limited to electrolytically conducting liquids, the response time and data quality of this technique make it clearly superior, where applicable, to all other forms of corrosion monitoring.

Injection and Sampling Systems
Injection systems may be as simple as using an open-ended tube that allows for even distribution of the injected chemical or as complex as using a head with a cap and core to obtain precise atomization of the chemical.
- Injection systems are used to inject a wide range of chemicals into processes. Such chemicals include:
- biocides and demulsifiers
- corrosion inhibitors, and oxygen scavengers,
- glycol and monoethylene glycol,
- dewaxers and methanol.
Sampling systems are used to take samples of the process fluid or medium. Such samples are then analysed in the laboratory for inhibitor concentration levels, the presence of metal ions, oxygen levels, scale forming compounds, and a wide range of process parameters.
Polarization Resistance
This technique has been used successfully for over thirty years, in almost all types of water-based, corrosive environments. Some of the more common applications are:
- Cooling water systems
- Secondary recovery system
- Potable water treatment and distribution systems
- Waste water treatment systems
- Pickling and mineral extraction processes
