Credit-Card-Sized Air Corrosivity Sampler

CorrAlert™ provides visual warning of corrosive gases and particles in technology spaces, museums, archives, cleanrooms and more.

Advertise with samplers printed with your company information.

Sampler Features:

  • We offer leading edge lab tests including corrosion film thickness corresponding to standard ANSI/ISA-71.04-2013 as well as corrosion film composition. See "Laboratory Reports".

  • Made to order. You can choose from a wide selection of reactivity coupons. See "Reactivity Coupons".

  • Non-marking & removable adhesive tab. Simply stick to a wall to start monitoring. Can also be mounted inside racks, display cases and vaults.

  • Recommended test period: 30 to 365 days.

  • Super fast worldwide shipping with UPS. Most orders are delivered within 1 week.

Kit contents: Sampler, instructions and postage paid sampler mailer for laboratory processing.

CorrAlert™ samplers are made to order with 1 to 6 reactivity coupons. When ordering you can select any combination of the following indicators:

  • Copper (Cu)
  • Silver (Ag)
  • Lead (Pb)
  • Iron (Fe)
  • Zinc (Zn)
  • Tin (Sn)
  • Aluminum (Al)
  • Nickel (Ni)
  • Gold (Au) Plated
  • Air Particles (PRT)

Also available are metal alloys including Al 7050, Al 7055 (aircraft alloys), INVAR 36, bronze, brass, steel alloys and many others. Please contact us for details.

Typical Coupon Combinations:

Mission critical facilities including data centers, server rooms and control rooms:

  • Particle (PRT)
  • Gold (Au) Plating *
  • Copper (Cu)
  • Silver (Ag)

* This is an important test for predicting electrical/electronic equipment reliability since much electrical equipment uses gold plating in connectors and PCB boards.

Museums, art galleries, archives and archival exhibits:

  • Particle (PRT)
  • Lead (Pb)
  • Copper (Cu)
  • Silver (Ag)

Cleanrooms, laboratories and hospital operating rooms:

  • Copper (Cu)
  • Silver (Ag)

Industry, offices and workplace:

  • Particle (PRT)
  • Copper (Cu)

Our laboratory offers a wide range of test reports including:

  • Corrosion film thickness (Å/30 Days) corresponding to standard ANSI/ISA-71.04-2013
  • * Total soluble salts (TSS) in (ug/cm2) including nitrates, sulfates, sulfides, carbonates and hydroxides.
  • Air particle concentration corresponding to standard ISO 14644-1
  • pH
  • Pitting Corrosion Report
  • Gold Plating Corrosion

* While standard ANSI/ISA-71.04-2013 is based on total corrosion film thickness we believe that total soluble salts in corrosion films is a much more important metric. For example, a corrosion film may be very thin but have a very high level of corrosive soluble salts.
