Salt Spray Chamber

Salt Spray Chamber for Corrosion Testing

SC Series

Salt spray chambers for long-term corrosion testing (over 240 hours)

NK by NEURTEK’s corrosion test chambers are designed to reproduce, in an accelerated and controlled manner, the environmental conditions that cause the degradation of materials, coatings and components. They are available in two ranges covering the main internationally recognised corrosion test methods:

  • SC Series (NK-SC500 / NK-SC1000): salt spray chambers for long-term corrosion testing (over 240 hours). They incorporate a peristaltic pump, a Venturi nozzle and an external 90-litre brine tank.
  • HC Series (NK-HC500 / NK-HC1000): chambers for testing resistance to condensation. They generate a homogeneous saturated humidity environment through the continuous evaporation of water at the base of the chamber.

 

Both ranges share the same fibreglass-reinforced plastic (FRP) construction, a transparent domed cover with 360° visibility, an intuitive touch screen and a wheeled design with brakes to facilitate installation and movement. Backed by over 40 years’ manufacturing experience.

Application

The SC500 and SC1000 chambers are specifically designed for long-term salt spray testing in accordance with ISO 9227, ASTM B117, ASTM G85-A5, DIN 50021 and JIS Z 2371. The peristaltic pump ensures a constant flow of brine to the Venturi-type atomising nozzle, made of PMMA with an integrated brine filter to prevent blockages.

  • Heating is provided by heating blankets on the tank walls to ensure uniform heat distribution.
  • Compressed air humidifier with level sensors and a safety thermostat.
  • External 90-litre brine tank, easier to fill and clean than an integral tank.
  • Operates with the base filled with water (greater thermal stability) or dry.
  • Optional thermal insulation blanket for the lid available for greater efficiency and higher maximum temperature.
  • Options ASC-ACC53/1 (SC500) and ASC-ACC53/2 (SC1000) for Prohesion testing in accordance with ASTM G85-A5.

Features

  • Fibreglass-reinforced plastic (FRP) construction: durable, impact-resistant, chemical-resistant and corrosion-resistant.
  • Dome-shaped, transparent cover with 360° visibility; remains open in a self-supporting position.
  • Touchscreen with an intuitive interface for test configuration and monitoring.
  • Wheels with brakes and forklift pockets: easy to install and move.
  • All connections (electricity, water, air, drainage) centralised to simplify installation.
  • Simple and reliable design, backed by over 40 years’ manufacturing experience.
  • NEURTEK’s own technical service with 48-hour support across the Iberian Peninsula.

FAQS

It is commonly used to evaluate steel, aluminium, galvanised steel, painted components, coated parts, anti-corrosion treatments and components intended for use in aggressive environments.

Salt spray chambers reproduce controlled and accelerated conditions. In real-world service, additional factors such as UV radiation, variable humidity, temperature, industrial pollution or marine environments also come into play.

It means that it has been subjected to an accelerated test for that duration under controlled conditions. However, the hours of exposure do not directly equate to years of service life in real-world conditions. 

The most common causes are insufficient surface preparation, inadequate coating thicknesses, mechanical damage, aggressive environments or defects in the protective system.
