Guides

The access opening, how far you must reach and whether you need to look around a bend decide which borescope or videoscope suits. This guide compares fibre-optic, video and articulating units, with recommendations and prices.

The liquid, the pipe it runs in and whether you need a portable check or permanent monitoring decide which flow meter suits. This guide compares clamp-on, insertion, Doppler, electromagnetic and oval gear meters, explains what the meter needs to know about the pipe, and recommends instruments with prices.

Whether you need a spot reading, a dew point check, a non-contact surface temperature or a logged record over time decides which instrument you need. This guide explains the options, the calibration and logging questions, and recommended instruments with prices.

Start with the parameters that matter for your water and whether you need spot checks or continuous monitoring. This guide explains pH, conductivity, dissolved oxygen, turbidity and chlorine, the calibration each needs, and which meters suit each job. Meters support operational checks; they do not replace laboratory testing.
