Designed for industrial, commercial, and export environments where reliability matters..
Instant Visual Feedback
Know the moment your air line becomes contaminated with a clear, unmistakable colour‑change indicator.
Simple, Zero‑Maintenance Design
No electronics, no calibration, no power — just plug it inline and replace the strip when needed.
Reliable Protection for People & Equipment
Continuously monitors air purity to safeguard operators, breathing systems, and sensitive machinery.
Innovation That Goes Beyond Air
A new generation of Inline Indicators is on the way — expanding our visual detection technology from compressed air into liquid and gas systems. The same simple, reliable colour‑change system, engineered for even more industries and applications.
Why Contamination Goes Unnoticed — Until It’s Too Late
Compressed air contamination doesn’t announce itself. Moisture, oil, and particulates slip into the system quietly, moving through hoses and tools long before anyone sees a symptom. By the time operators notice a defect, a failure, or a safety risk, the damage is already done. Understanding how these hidden events unfold is the first step toward preventing them — and why real‑time visibility is so critical
Step 1
Contamination Enters the Line
Moisture, oil mist, dust, or chemical residue enters the compressed air system through compressors, hoses, fittings, or environmental exposure — with no visible warning.
Step 2
It Moves Unnoticed Through the System
Once inside, contaminants travel silently through air lines. Operators can’t see it, gauges don’t show it, and equipment keeps running as if everything is normal.
Step 3
Damage Happens Before Anyone Realises
By the time contamination becomes visible, the harm is already done — ruined coatings, clogged tools, failed equipment, or unsafe breathing air.
Step 4
The Problem Is Found Too Late
Most operators only discover contamination after a failure, a defect, or a safety incident. Without a visual indicator, there’s no early warning and no chance to prevent the loss.

Built by Specialists Who Understand the Problem
The Inline Indicator is the result of collaboration between engineers, manufacturers, and industry partners who share a single goal: make contamination visible before it causes damage. Together, we’re building a platform that will expand across air, gas, and liquid systems in the years ahead.
James Mills ,Founder
“When a tool is truly simple, it disappears into the workflow → that’s when it does its best work.”
The Inline Indicator draws a small sample of your compressed air across a replaceable cartridge that reacts to moisture, oil mist, particulates, VOCs, and chemical residues. As contaminants build, the strip shifts through clear colour stages visible through the top window — no power, calibration, or tools required.
If the strip shows contamination **or** reaches its end‑of‑life colour, the cartridge is replaced from the bottom in seconds. A keyed fit ensures correct alignment, and the snap‑lock holds it securely in place while the main line stays connected.
It’s a simple, robust, passive way to monitor air quality continuously and catch problems early.
Only the Beginning of What It Delivers
Instant visibility into the air your team relies on, giving operators confidence that every breath is clean and safe.

Need a Custom Fit?
The Inline Indicator is designed for rugged environments — but we know every application is different. Whether you need a unique hose interface, mounting solution, or integration with your existing systems, our engineering team is ready to collaborate. Let’s explore what a custom version could look like for your operation.
Questions you might have
We know adopting new technology raises questions. This section covers the most common things people ask about the Inline Indicator — from compatibility and durability to industry use cases — so you can feel confident in how it performs.
What does the Inline Indicator actually detect?
It visually flags air or fluid quality issues — including contamination, pressure loss, or flow disruption — using a multi-color display. It’s designed for real-time monitoring in industrial and export environments.
Is it compatible with my existing hose or system?
The standard version fits common smooth hoses. For specialty setups, we offer custom designs — including alternate diameters, mounting options, and chemical-resistant substrates.
Does it require power or electronics?
No. The Inline Indicator is a passive device — no batteries, no wiring. It uses engineered materials to respond to environmental changes. We will have an electronic sensor design in the near future.
Once installed how long does the cartridge last?
The Inline Indicator is designed to remain active for the full duration of normal use — whether that’s a production shift, a spray job, a blasting cycle, or an export shipment. Its lifespan depends on the environment it’s exposed to. Clean, stable systems allow the indicator to remain unchanged for long periods, while contaminated or unstable systems will trigger the color change sooner. The indicator does not “expire” during use; it simply reacts when conditions cross the threshold it’s designed to detect.
Can I request a custom version?
Absolutely. We welcome technical inquiries and pilot requests. Use the contact form to start a design consultation.
How does the color change work?
The indicator uses engineered materials that respond to environmental triggers — such as moisture, oil, or pressure changes — by shifting color. No electronics or calibration required.
Can it detect contamination in compressed air?
Yes. The Inline Indicator is designed to react to oil mist, water vapor, or particulate contamination depending on the chemistry used. It’s ideal for visual confirmation in sensitive environments.
Is it suitable for sterile or pharmaceutical use?
Absolutely. We will be offering cleanroom-compatible versions with low outgassing materials and sterile packaging options for pharma and electronics applications.
What’s the shelf life of the replacable cartridge?
Standard shelf life is 12–24 months depending on the chemistry. Custom versions may vary — we provide full documentation with each batch.
Can I use it in liquid systems?
Yes — we’re currently developing a liquid-line version for water, solvents, and other fluid systems. Contact us to join the pilot program or request early samples.
