Reliable Moisture Analysis for Aggregates, Concrete and Cement Testing
If you work in civil engineering or construction, you already know this: moisture is one of those small variables that can quietly create big problems.
Too much or too little water in your aggregates, cement, or concrete mix doesn’t just affect lab results - it shows up on site as cracking, poor compaction, inconsistent strength, delays, and rework. That’s why getting moisture measurement right, quickly and reliably, matters so much in day-to-day construction and materials testing.
At Hylec Controls, we work closely with engineers and laboratories across Australia and New Zealand as the exclusive distributor for James Instruments, supporting teams who need practical, field-ready moisture testing - not complicated lab-only processes.
Three instruments are used every day by civil engineers, technicians, and materials labs to keep control of moisture where it matters most: the Aquameter, Aggrameter, and Cementometer Type L.
Aquameter – for when you need quick answers on site or in the lab
If you’re on-site or running batch checks and need a fast moisture reading in concrete or general building materials, the Aquameter is the go-to tool.
Engineers use it when they don’t have time for delays or lab turnaround. It gives you quick, practical readings so you can decide straight away whether materials are within range or need adjustment.
It’s especially useful during pours and early-stage checks, where small moisture changes can affect workability and finishing.
Aggrameter – keeping your aggregates under control
Anyone working with concrete production knows that aggregates can change constantly depending on stockpile conditions, weather, and handling.
That’s where the Aggrameter comes in.
Civil engineers and batching plant technicians use it to check sand and aggregate moisture before it goes into the mix. It helps you keep your water–cement ratio under control and avoid the all-too-common issues of wet sand throwing off your design mix.
In practice, it means fewer surprises at the plant and more consistent concrete on site.
Cementometer Type L – for precise cement moisture control
Cement doesn’t tolerate guesswork. Even small moisture variations can affect setting time, strength development, and overall performance.
The Cementometer Type L is used by technicians and engineers who need a reliable way to monitor cement moisture and ensure consistency before it ever reaches the mix.
It’s a simple but important tool when you’re trying to maintain tight quality control and avoid variability in performance-critical applications.
Built for the realities of construction and testing
Whether you’re working in a materials lab, running a batching plant, or managing quality control on a civil infrastructure project, these three instruments are used for one reason: to take uncertainty out of moisture measurement.
The Aquameter, Aggrameter, and Cementometer Type L give you practical control over the materials you’re working with every day - helping you stay within spec, reduce rework, and keep projects moving.
