The Signal [FID] instruments are rugged, accurate and reliable, and we are obviously delighted that they have provided so many years of reliable service. To maintain this high level of performance, the instruments’ linearity is checked annually and Signal services the instruments twice a year

Our customer purchased Signal Group’s latest fixed, heated FID, the S4 SOLAR, and we needed a little help with setup and commissioning because the customer wanted to calibrate his device with a special gas rather than propane. We therefore contacted Signal and they were able to log into the analyser remotely and quickly changed the analyser settings. Following this amendment, the analyser was operational in no time. As a result, the customer was delighted and said that Signal’s remote diagnostic capability was a very pleasant surprise!

“The Gas Divider has worked very well; helping us to assure the accuracy of our measurements, whilst reducing the number of calibration gas bottles required. This reliability is further assured by regular calibration checks that are performed by Signal Group.
