1. Process Instrumentation Calibration Service
Why do I need to have my instruments calibrated, even when they’re new?
Calibration is the act of adjusting the accuracy and precision of an instrument; an instrument which does not have a current calibration cannot be relied upon to provide an accurate measurement or control response.
If the instrument forms a quality critical role in a process, then the integrity of the whole process is compromised if an instrument is out of calibration.
All instruments need to be calibrated; in the same way that a chain is only as strong as its weakest link, then a process is only as reliable as its least accurate instrument.
Even brand-new instruments need to be calibrated. Depending on the type of instrument its ability to read precisely and accurately may have been compromised during its shipping or installation. It’s important to establish a benchmark calibration at the time of initial commissioning.
You can think of calibrating an instrument as being a bit like adjusting your watch. Even the most complex and expensive watch or clock is prone to losing or gaining time. When you plug in a new electrical appliance for the first time, its digital clock display may already show a time, but it’s wise to check that time against another time source that you know to be reliable. From time to time, as the accuracy of your watch drifts, you need to bring it back into calibration.

2. Gas Detector Calibration Service
Like process instrumentation, gas detection instruments require periodic calibration to ensure that they are providing accurate readings of their target gas(es).
Calibration of gas detectors is a process of exposing the gas detector to a benchmark sample of calibration gas.
Calibration gas is a precise mixture (which varies according to the target gas of the instrument being calibrated) and is manufactured to traceable standards.
To ensure the accuracy of gas detectors – whether it be a relatively simple portable instrument or a complex fixed-point instrument – it should be regularly calibrated in accordance with its manufacturer’s procedures and recommendations.
As an experienced supplier and gas detector calibration service provider for a wide variety of gas detection equipment, Entec stocks a range of calibration gas and our team of service technicians are highly competent at calibrating gas detectors in the field, or in one of our calibration laboratories.
