2020 – Part 1
A few words from our CEO
We are humble in the times that now prevail and try to adapt to the circumstances. We always have our staff on site just as alert as usual to answer your questions. We are manned from both offices, but some of us also work from home. Our stocks are a little extra filled to be able to deliver the products we normally sell most of. Everything from pumps to spare parts and consumables. So far, transportation works both to and from us. We have had a supplier that had to shut down completely, but they are now back in production for a few days. At present, you can send in pumps for repair and calibration sensors.
Our method for calibrating vacuum sensors is accredited.
Our goal and ambition to adapt to the environment is a fact! We are environmentally certified according to ISO 14001:2015. We now have all processes in place to deliver and control our organization in an environmentally safe way.
A new product from Hiden Analytical! – Portable Gas Analyzer
The Hiden pQA (portable Quadrupole Analyzer) is a versatile and easily customizable mass spectrometer system. It is available with a large number of inlet types for different types of samples and sampling methods. Real-time analysis of gases from industrial and fermentation processes and with MIMS technology also of dissolved gases in liquids. Portable and ideal for field measurements. For 12 V or 24 V operation in the field and 220 V in the lab. Clear advantages in handling and efficiency provide time savings compared to traditional sampling. Professional compact transport bag with extendable handle and wheels.
With a spectrum of 200 alt. 300 amu and detection to sub-ppb levels and high stability make it an all-in-one solution that enables data collection of laboratory quality data when you’re on the go.
The Hiden MASsoft software provides easy control of parameters and control of connected equipment and provides a unique opportunity for so-called. soft ionization for reduced fragmentation in complex gas mixes. The market’s maybe non plus ultra software for easy data interpretation of the samples with eg. 3D.
Examples of applications:
- Monitoring of environmental factors in real time
- Fermentation processes and biogas
- Analysis of soil and drill cores
- Water analysis in swimming pool, reservoir, stream and river, drain and outlet and sea and sea samples
- Groundwater Studies
- Pollution tracking
- Microbiological / enzyme activity studies
Leybold Graphix is part of the latest and most modern series of instrument displays on the market.
With its color touchscreen, it provides superior readability in many ways.
Choose how you want to view the display, large numbers, digital viewer or connected directly to your computer. Connect up to 3 sensors to the same instrument and 6 set points with relay outputs. Choose to see 1 sensor at a time or all 3 at a time. See graphs and charts directly in the color display.
Graphix’s features are very user-friendly and have a simple intuitive interface. Perfect for those who do not like manuals. All Leybold’s sensors are automatically identified and you can easily set the characteristics to the active brand’s active sensors.
Make your leak detection easy with pressure rise test. Trend analysis recording function gives you complete control over your vacuum system.
A selection of features and benefits of Graphix:
- Measuring range from 1×10-10 to 2000 mbar
- High quality 3.5 inch color touchscreen
- Fill out the information from Graphix to USB, output both on the front and back
- Simple pressure rise test to check for system leakage
- 6 relay functions ”set points” with clear display on the display
- Function for degassing ionizing ITR sensors
- Communication via RS232 C / RS 485 C
- Easy mounting in rack cabinet
- LeyAssist software for PC provides clear visualization of values and measurements.

We have an addition in the Low2High team, we welcome Olle Floxgård who has started at our office in Uppsala. He brings more than 10 years of experience in the vacuum field, both as a salesman and service technician. We hope he will enjoy working with us!
Are your sensors measuring right?
Ensuring that your application or process works properly is more important today than ever to avoid wasting time and / or money. All companies, large and small, nowadays have some kind of quality system to ensure quality products. Scheduled repairs, recurring service and calibration are an important part of securing your production and providing a secure future for the company.
Many times we get calls from customers who think that there is something wrong with their vacuum pump because the cycle time on their process has slowed down or that something in the production is not working. Most often it is not the pump that is broken, but it is your sensor that shows the wrong value. Of course, this affects the entire production and you lose time or money because your process is not working properly.
For example, our calibration manager, Niklas, was at a customer where it was suspected that there was some overall error in their system due to the deterioration of cycle time. Much of the production was depending on a certain value being achieved before the next step in the process could start, so it was important for the sensors to show correct measurement. When Niklas tested with a calibrated sensor on the system, it turned out that it was their sensor that gave faulty results. If the customer had continuously and regularly calibrated their sensors, they could have ensured that they got the right value and could saved time in the process.
Most companies today have quality requirements from their customers on products that the company manufactures. By calibrating their sensors, you gain increased control over the quality of the final product. In addition, some processes are so sensitive that a dirty sensor, or a sensor that shows errors, can affect the result so much that the product isn´t useful and simply must be discarded.
When calibrating a vacuum sensor, we determine the deviation in measured values between the instrument and a traceable normal. If you can quickly deduce a fault with, for example, a dirty sensor instead of always assuming that the pump is broken, you can save a lot of money. We can offer a traceable calibration from 1000 mbar – 1×10-5mbar. The interval you should have between the calibrations depends entirely on your process. If you have a clean process where the sensor does not become contaminated or dirty, then 1 year or more between calibrations is appropriate. Should you instead have a process with a lot of dust, oil or something else that can contaminate your sensors, the interval should be shortened to ensure that the sensor shows correctly.
We at Low2High Vacuum AB have our vacuum calibration method accredited by Swedac according to standard SS-EN ISO / IEC 17025: 2018. What does this accreditation mean? Yes, our method is checked annually by Swedac, which is a national accreditation body and an authority. The agency accredits laboratories, certification bodies and control bodies in accordance with international standards and regulations. Through our accreditation we give assurance to you as a customer that we can ensure our quality and the competence of our employees.
