If your calibration needs to happen in the field, your equipment needs to be ready to go with you. The Gilian Go-Cal Pro combines NIST-traceable accuracy with a lightweight, rugged design and USB-C charging, making it practical for occupational hygiene teams working across multiple sites. Reliable calibration, wherever the working day takes you.

When filter media loads, back pressure increases, and that can challenge the performance of a low-flow air sampling pump. The Gilian LFS Pro is designed to maintain stable, accurate flow as resistance increases, helping protect the integrity of the air sample throughout the monitoring period. Compact, quiet and built for demanding low-flow applications, it gives occupational hygiene professionals confidence that their sampling equipment can keep performing when conditions become more challenging.

How often is an air sample compromised by a pump moving out of position, flow drift or an interrupted sampling period? With regular Shawcity Service & Calibration, your Gilian LFS Pro can continue to deliver the stable, reliable flow required for accurate personal exposure sampling. Consistent performance helps reduce the risk of failed samples, supports reliable data and gives occupational hygiene teams greater confidence in their monitoring results.

Personal exposure air sampling is one continuous task, even though it's usually sold as separate purchases. The Gilian Go-Cal Pro calibrates the flow. The Gilian LFS Pro holds it, quietly, through a full shift. Together they cover set-up to sample without a gap in the chain, engineered by Sensidyne, supplied and supported across the UK by Shawcity.

Reliable exposure data starts with accurate calibration. With the Gilian Go-Cal Pro, calibration events are recorded and stored, with printable reports available when you need them. It provides a clear, traceable record of the checks carried out before and after air sampling, helping occupational hygiene teams maintain confidence in their monitoring data and demonstrate that the correct process has been followed.

During air sampling, as material collects on the filter, back pressure rises. If the pump can't compensate, the flow rate can drift away from its setpoint, potentially compromising the sample. The Gilian LFS Pro is built to hold flow through that rise, with up to twice the back-pressure capability of comparable pocket-sized pumps. It's a small spec on a data sheet that decides whether a shift's sampling is usable.
