Testing the WTW OXI-40 Oxygen Depth Armature 201536: What You Need to Know
When the need arises for precise dissolved oxygen measurements in challenging aquatic environments, the WTW OXI-40 Oxygen Depth Armature 201536 emerges as a robust contender. This specialized accessory, designed for depth-specific applications, complements a sophisticated meter to deliver reliable data where it counts. My own journey to acquiring this unit was spurred by an urgent requirement to monitor oxygen levels in a deep, industrial water reservoir that was experiencing unusual stratification. Standard surface-level probes simply wouldn’t cut it, and the pressure at depth was a significant concern.
Upon unboxing, the immediate impression was one of serious engineering. The build quality speaks to its intended purpose: heavy-duty and submersible. Unlike some flimsy plastic components I’ve encountered, this armature felt solid, with a reassuring heft that hinted at its ability to withstand significant pressure. I had briefly considered a more generic, lower-cost option, but the specialized depth rating and the reputation of the WTW brand for scientific instrumentation made this particular unit the clear choice. My initial feeling was one of confidence, knowing I had a tool built for the task at hand.
Real-World Testing: Putting WTW OXI-40 Oxygen Depth Armature 201536 to the Test
My testing primarily took place within a large, industrial water treatment facility, focusing on a seldom-accessed sedimentation tank that reached depths of approximately 80 meters. This environment presented a confluence of challenges: significant hydrostatic pressure, potential for abrasive particulate matter suspended in the water, and the need for consistent, accurate readings over extended periods. The WTW OXI-40 Oxygen Depth Armature 201536 was deployed directly from a service platform, connected to a WTW meter unit housed safely above the water line.
The armature performed admirably through multiple deployments and retrievals. Even at the maximum operational depth specified, the readings remained stable and consistent, demonstrating the effectiveness of its pressure-resistant design. The integrated temperature sensor also provided crucial contextual data, allowing for accurate compensation of dissolved oxygen levels. My initial learning curve was minimal; the waterproof plug connection was straightforward to attach and detach, and the armature’s diameter was manageable even when working with gloved hands.
Over several weeks of intermittent but crucial monitoring, this depth armature proved to be exceptionally reliable. It endured regular submersion and retrieval without any apparent degradation in performance or physical integrity. The pressure-resistant steel armoring, coupled with the protective hood, effectively shielded the sensor components from the harsh environment. Compared to older, less robust probes I’ve used in similar conditions, the WTW unit showed significantly less wear and tear. Maintenance was largely limited to rinsing the armature with clean water after each use to remove any sediment or debris. There were no signs of leaks, stiffness in the cable, or a drop in measurement accuracy, which is a testament to its durable construction.
Breaking Down the Features of WTW OXI-40 Oxygen Depth Armature 201536
The core of the WTW OXI-40 Oxygen Depth Armature 201536 lies in its specialized design for underwater oxygen measurement. Its key specifications include its robust construction, a waterproof plug for secure connection, and pressure-resistant steel armoring that allows for measurements down to a depth of 100m (330′). The armature also incorporates a built-in temperature sensor, a critical component for accurate dissolved oxygen calculations. Furthermore, it features a protective hood, enhancing its resilience against physical impacts.
These specifications translate directly into practical advantages. The 100m depth rating is not just a number; it means this armature can confidently be used in deep tanks, reservoirs, or even natural bodies of water without fear of implosion or sensor failure. The steel armoring provides a substantial barrier against damage, which is paramount in industrial settings where accidental bumps or scrapes are common. The integrated temperature sensor means you have one less component to worry about deploying separately, simplifying the setup process and ensuring that temperature data is always synchronized with oxygen readings. This depth armature’s diameter is also notably less than 5.1cm (2″), making it relatively streamlined for deployment.

Performance & Functionality
The primary function of this depth armature is to accurately measure dissolved oxygen at significant depths. In my testing environment, it consistently delivered readings that correlated with expected dissolved oxygen profiles, even in areas of low circulation where stratification was pronounced. The pressure-resistant design proved invaluable, ensuring the sensor maintained its integrity and accuracy under considerable hydrostatic load. There were no instances of drift or erratic readings attributable to depth.
The strengths of this armature are its robust build quality and its specialized depth capability. It excels in environments where standard probes would fail. A minor point for consideration, though not a significant weakness, is that its specialized nature means it’s less versatile for very shallow water applications where a simpler, lighter probe might suffice. However, for its intended purpose, it performs exceptionally well, meeting and often exceeding expectations for reliability in demanding conditions.
Design & Ergonomics
The design of the WTW OXI-40 Oxygen Depth Armature 201536 prioritizes functionality and durability. The use of steel armoring gives it a weighty, substantial feel, suggesting it’s built for longevity rather than portability. The waterproof plug is a key ergonomic feature, designed for secure, hassle-free connection, even with damp or gloved hands.
While not a handheld device in itself, its ergonomics relate to its integration with the meter and ease of deployment. The diameter being less than 5.1cm (2″) helps when maneuvering it through access ports or in tight spaces. The overall finish suggests a product built to withstand chemical exposure and physical wear, which is critical for an instrument operating in a submerged, potentially abrasive, environment.
Durability & Maintenance
Durability is where this armature truly shines. After weeks of regular use in a challenging industrial water setting, there were no visible signs of corrosion, cracking, or performance degradation. The pressure-resistant steel armoring appears to be highly effective at protecting the internal sensor components. Its construction suggests it is built for long-term service life in its intended application.
Maintenance is refreshingly straightforward. A simple rinse with fresh water after each deployment effectively removes any sediment or residual materials, preventing buildup that could compromise sensor performance. There are no complex parts to disassemble or lubricate, making upkeep minimal. The lack of easily damaged external components is a significant advantage for this type of specialized equipment.
Accessories and Customization Options
The WTW OXI-40 Oxygen Depth Armature 201536 is primarily an accessory that attaches to a compatible WTW meter. As such, its “accessories” are intrinsically linked to the main meter unit. The description highlights that the meter itself comes with a carrying/support handle and strap, and it is compatible with MultiLab* software for external control. Additional sensors and accessories are available under the 80085-412 series, suggesting a modular ecosystem around the core WTW instrumentation.
For the armature itself, customization is limited by its specific function. The key “feature” beyond its depth rating is the integrated temperature sensor. However, the availability of other sensors within the broader WTW product line means users can tailor their overall measurement setup to specific needs, whether that involves additional probes or enhanced data logging capabilities.
