Which IPLEX videoscope to choose: One, NX, GX/GT, GAir or TX II

Remote visual inspection without model confusion

The IPLEX range covers one task — looking where the eye and a phone camera cannot reach: turbines, heat exchangers, pipework, narrow cavities, castings. The difference between models lies in probe diameter and length, measurement capability, ergonomics and whether you are building one platform or buying a narrow-purpose tool.

Below is a practical guide for power, oil and gas, aviation MRO and NDT contractors.

Quick matrix

Scenario	Model
A new single RVI platform for years ahead	IPLEX One
High image quality plus 3D measurement (the classic)	IPLEX NX
Price/feature balance, interchangeable probes	IPLEX GX/GT
Compact rounds and routine visual checks	IPLEX G Lite
Long tubes / heat exchangers of 20–30 m	IPLEX GAir
Very narrow access of 1.8–2.2 mm	IPLEX TX II

IPLEX One — a platform, not "one more videoscope"

The IPLEX One is the 10th generation: common hardware, Plus / Expert / Prime tiers through software, Swoptix (switching near/far and direct/side without changing the tip), 3DAssist, a ~10″ screen and ViSOL integration.

Choose it if:

• you want to standardise the RVI fleet on one platform;
• speed of inspecting turbines and cavities and measurement without swapping tips matter;
• you plan a digital reporting workflow.

Not essential immediately if you only need occasional inspection of short cavities — it is cheaper to start with the G Lite / GX.

IPLEX NX — the proven imaging flagship

The IPLEX NX remains a strong choice where image quality, stereo/3D measurement and a familiar interface are critical. Typical probe lengths start at a few metres, with diameters around 4–8 mm depending on configuration.

It suits turbines, combustors and complex internal volumes where "seeing the defect" matters more than the length of the run.

---

IPLEX GX/GT — the working middle ground

The IPLEX GX/GT balances brightness, interchangeable probes and cost of ownership. It suits service crews that need a universal videoscope without buying the whole One ecosystem.

---

G Lite — compact for regular rounds

The G Lite / G Lite W is for frequent inspection with routine tasks: quick visual checks, mobility, less heavyweight metrology.

---

GAir — when you run out of length

The IPLEX GAir covers 20 m and 30 m with pneumatic articulation. It is not a replacement for an NX/One on a turbine: it is a tool for long pipelines, heat exchangers and long channels.

If the specification says "reach 25 metres", an ordinary IPLEX will not save you without a GAir (or an equivalent reach).

---

TX II — ultra-thin access

The IPLEX TX II is flexible at ~2.2 mm or rigid at ~1.8 mm. It is needed for small openings, castings and narrow channels where a 4–6 mm probe physically will not pass.

TX II is often used as a scout, with measurement and detail work then done by a 4–6 mm system.

How to state the requirement to a supplier

1. Access diameter (mm) and run length (m).
2. Whether measurement is needed (scalar / stereo / 3D) or only photos and video.
3. The environment: oil, temperature, ATEX / hazardous area, remote control unit.
4. One instrument for everything, or a combination (for example TX II + One/NX + GAir).
