Service & Support at Rotronic UK

casestudy

At Rotronic we can offer a wide range of humidity and temperature measurement products, and our dedicated staff are on hand to support with any calibration, technical or sales queries, our products are supported by a network of subsidiaries and distributors worldwide.

What we can we offer?

ISO17025

We are recogonised globally for our ISO 17025 calibration lab, calibration is the only way in which you can confirm an instruments performance. Many regulatory bodies now require instruments to be regularly calibrated to specific standards.

Here at Rotronic UK we provide a range of calibration services from our dedicated on site laboratory including UKAS accredited (ISO17025) calibrations and calibrations that are traceable to national standards. We also provide custom factory calibration and testing for OEM devices.

System Validation

Our products and software are designed to meet the requirements of GAMP5 and FDA 21 CFR Part 11. Validation provides clear documented evidence that specific monitoring systems meet these requirements, that are demanded by a growing number regulatory organisations.

What you can expect from our validation service

  • Creation of user requirment specifications (URS)
  • Preparation of validation plan
  • Development of validation risk assessment and SOPs
  • IQ,OQ,PQ testing, documentation and reporting
  • Final validation reports

Logging Solutions from Rotronic

In this post we take a look at the important questions you should ask when looking for data loggers.

Since our founding over 50 years ago, data logging has always been a key requirement for our customers and as technology and regulations have evolved so have our products and solutions. We now offer a wide range of devices but it can get confusing knowing which approach to take.

Logger Solutions_sm

When choosing a logging solution consider the following areas…

  1. Parameters – What environmental conditions do you need to measure eg Humidity and Temperature
  2. Accuracy/Calibration – How accurate do you need the results and do you require calibration.
  3. Environmental Conditions – Both the logger operating conditions and monitoring conditions.
  4. Access to Data & Reporting – Live data, manual download etc, software and reporting tools
  5. Local Display – Live values, max/min and local alarming
  6. Power Requirements – Mains, battery or PoE (power over ethernet)
  7. Memory – How long can the device log and is data stable if power is lost
  8. Cost – What it often boils down to, but always consider the cost of not changing what you are doing

Lets look in a bit more detail…

Parameters – Fairly self-explanatory but consider things like calculated parameters (dew point) , it might be better to use two separate devices rather than one. Rotronic offer Humidity, Temperature, CO2, Differential Pressure and Barometric pressure probes, but also many of our loggers accept analogue input signals so you can utilise existing or 3rd party instrumentation.

Accuracy & Calibration – Accuracy specifications can be mis-leading, if you care about your measurements we would always advice pre-delivery calibration. Also consider that often bulky loggers can be slower and more costly to calibrate vs devices with external probes. When considering humidity measurements drift is also a key factor.

Environmental Conditions – Consider both those you need to measure and where the logger will be placed. Many loggers have cable probes that can tolerate adverse conditions where the logger itself cannot. Also be wary of battery life, it is typically only stated for use at ambient conditions.

Access to Data / Reporting – Simple loggers typically require manual downloading of data. For large installations or where regular reporting is required this can quickly become a laborious task. Alternatively look for devices with a permanent connection to the monitoring software. Our latest RMS software provides live alarms, automated reports and users can access live data through a simple web browser, often saving time and money in the long run. Simple reporting is also key so that data can securely be shared. In compliant applications you may also require the ability for users to validate report authenticity.

Local Display – Useful for many applications but as data becomes always available can a mobile device act as the display for you data logger. For large spaces consider the ability to build dashboards in your software so that users can see data whilst operating.

Power Requirements – Devices with non user replaceable batteries lead to downtime and additional costs. Where possible mains or PoE connections ensure battery life is not an issue. Our latest wireless devices ensure >3 year battery life even when logging and transmitting data every minute.

Memory – Should be secure in the event of battery or power failure and sufficient to last either between download events or as a back up in case monitoring software / network connections fail.

Cost – Best to be realistic with your budgets, consider the time costs for not acting and down forget on going service costs such as validation and calibration.

As you can see from the simple overview above it is virtually impossible to have one logger for every application. At Rotronic we have a diverse range of solutions and even these do not cover all eventualities.

If you have monitoring requirements please do contact us to discuss further.
