How to choose your CorrSen monitoring solution?

Design the monitoring solution most suitable for you application

Sensor material

  • If you want to assess the atmospheric corrosivity category according to ISO 9223 (outdoor; C1‒CX) or ISO 11844-1 (indoor; IC1‒IC5), choose the material specified in the standard.
  • If you want to monitor air corrosivity towards a specific material, choose a sensor with the composition similar to the material of your interest.

Thickness according to expected corrosivity

  • In less corrosive environments, you obtain the best sensitivity and reasonable longevity when using the lower corrosivity CorrSen sensors.
  • In harsh environments, the high corrosivity CorrSen sensors is recommended.

Compact version vs. sensors on a cable

  • Is the monitoring site easily accessible and large enough to place there the whole logger? If yes, choose the basic sensor modification with a sensor inserted to the logger.
  • If not, choose the sensor soldered on a 2-meter long cable. Note that the temperature and relative humidity measurement is not possible for this modification.

Permanently plugged-in CorrSen Gate with the dimensions 165×160×80 mm

  • Continuous data transmission thorough integrated GSM
  • Up to ten loggers connected to one gate
  • Perfect solution for a large number of stationary placed loggers
  • Necessary for the real-time warning of corrosivity increase
  • Gate has to be plugged-in and placed in a safe environment

CorrSen loggers are controlled and data obtained through NFC using a mobile phone

  • Ideal for remote locations without permanent power source and GSM
  • Applicable for a small number of loggers
  • Data not available in real-time
  • Physical presence of an operator is required to download the data
  • Free Android and iOS application available

Frequently Asked Questions

Did not find an answer to your question? Contact us

How does the measurement work?2025-04-28T23:05:19+02:00

CorrSen records electrical resistance of a thin metallic track deposited on a non-conductive substrate and exposed under corrosive conditions. As a result of corrosion, the sensor thickness decreases leading to the electrical resistance increase. It is directly recalculated to the corrosion depth, actual corrosion rate and environmental corrosivity. Owing to the simple operation principle, the device is easy to maintain and provides direct corrosion data in all types of atmospheres. Simultaneously with the corrosion rate, temperature and relative humidity are recorded helping to understand observed changes in the environmental corrosivity.

I want to monitor environmental corrosivity towards bronze. What sensor should I select?2025-04-29T16:46:17+02:00

Copper behaves in atmospheric conditions similarly to bronze. Anyway, if it is critical for you to monitor corrosivity towards a particular alloy we do not offer, we are able to produce a set of sensors with specific composition. Please, contact us using the Contact form.

Can I re-use the logger after the sensor is at the end of life?2025-04-29T16:46:58+02:00

The basic version of CorrSen can be re-used. Any free sensor or sensor on a cable can be plugged in and monitoring re-initialized. Sensors can be ordered separately using the Order form.

How often is the corrosivity measured?2025-04-29T16:47:26+02:00

The frequency can be set in the online CorrSen software. The optimal setting depends on the purpose of your measurement. If it is intended to follow long-term changes, once a day can be enough. If an understanding into mechanism is sought, it might be useful to measure each 5 minutes or even more often. For most applications, between 1 and 4 measurements per hour are sufficient.

Do you ship internationally?2025-04-29T16:48:32+02:00

Yes. CorrSen is delivered free of charge in European Union. Additional costs may apply for oversees delivery.

What is the battery lifetime? Is it possible to change it?2025-04-29T16:49:03+02:00

It depends on the measurement and data transmission frequency. With usual setting (1 measurement/hour, 4 transmissions/day), it powers the device for 3 years. The battery can be replaced for a fee.

Do I need to install my own SIM card to transmit data from CorrSen Gate to the server?2025-04-29T16:50:32+02:00

In European Union, it comes with the unit. Oversees, it needs to be purchased by the user.

How long does it take to get the corrosivity classification according to ISO 9223 or ISO 11844-1?2025-04-29T16:51:10+02:00

Strictly speaking, a year-long measurement is necessary for a correct classification. However, in most cases, a month is enough to have a good estimate.
