About Kemo

Kemo is a privately-owned company that has successfully been solving filtering and signal conditioning problems around the world since 1965. Started in South east England by mathematicians and electronic engineers, we are specialists in high quality analogue  filters, an area where sophisticated mathematical techniques and state-of-the-art circuit design converge.

Changes at Kemo Limited

Management of Kemo Limited changed at the turn of the 21st century. Some new members of staff have joined us, with extensive experience of measurements and signal processing. We have updated and rationalised a number of our products, and manufacturing processes. We work hard to keep many of the more standard products in stock, or available for delivery within one or two working weeks.

What do we do?

We design and manufacture electronic filters and signal conditioning systems in the frequency range of DC to 1MHz. Our products incorporate many signal conditioning features requested by users over the years. We also aim to introduce new features to improve system performance. This philosophy has resulted in the most extensive, flexible electronic filter product line available.
We have found over the years that some applications fall between the gaps in a standard product range. So we continue to engineer custom systems to many customer specifications.

How do we do it?

We aim to make electronic filters which provide consistent performance within filter response types from year to year. This enables our customers to collect data and analyze it with confidence. 
To do this we are like top quality chefs, we only use the best ingredients. Many of the capacitors we use are specially made for us, using the most stable materials available today. 
In many of our systems we match the capacitors to less than 0.02%, this gives us very consistent electronic filters, which are close to their theoretical performance. To the end user this means very consistent performance across a wide number of channels.
We often receive units which are >15 years old back for calibration, and they still meet the same specification that they were initially tested to when new. Are you still using a 15 year old PC?
The same applies to all components, we use the best we can find.

What tools do we use?

We use a range of industry standard circuit design packages, most of our circuit board layout we sub - contract to an established company who we have worked with for a long time, they layout boards every day, we do not, so they usually make a better job than we would. Mechanical design is CAD based, something which saves considerable time and effort. We e-mail a file and a few days latter we receive the parts. Its not paperless, but paper reduced.
All our electronic files are files are centrally stored on site on mirrored Solid State Drives, and then once a day backed up to offsite archieve quality magnetic discs. Totally under our control.

Who are you?

There is no such thing as a typical user of our products. We have a wide installed base, spread over the entire world, because so many activities in the scientific, technical and engineering fields require the filtering and conditioning of signals. Whether you read this guide as a newcomer to the need for signal conditioning and filtering, or as an experienced practitioner, we think we have products that will interest you, and which will offer valuable benefits in your projects.

Working at Kemo Limited

Some information about our working methods and mentality. 
Kemo Limited works a 35 hour 4 day week, so we all have one day off a week. We are keen supporters of training, and usually have one trainee from the local Technical College with us to gain experience. 
We aim to try our best to deliver on time, and with no impact on quality. HOWEVER some of the components we use are highly specialist and can have delivery times of over 20 weeks (our record is 40 weeks so far). We will keep you informed if your order is delayed.

Kemo and the Environment

We try to be green in the simple ways.
We have just installed modern high efficiency lighting in our offices and workshop, saving about 40% on our lighting energy. In fact we rebuilt the old fitting with modern electronics and tubes, a simple form of recycling. We have reflective film on the windows, so we use less air conditioning in the summer (or we open the windows and wear shorts to work) and less heating in the winter. We are an increasingly paper reduced office. We try to recycle paper, packing materials and boxes when we can.
We try our best, and most of the time we all use public transport to get to work, and that helps to keep us slim and trim as well.
