Instrava — Engineered for Reliable Measurement.
Instrava OEM/ODM
Instrava Engineering & Customization Support
At Instrava, our instruments are developed with a strong focus on real industrial applications. Each product is designed to operate as a reliable component within measurement, control, and automation systems, rather than as a standalone device.
Our engineering team supports customers during product selection by evaluating process conditions, operating environments, and system requirements, ensuring stable and long-term performance in actual use.
In addition to standard configurations, Instrava offers flexible customization options, including measurement range, materials, output signals, communication interfaces, and installation methods. All custom solutions are engineered to meet industrial standards and application-specific demands.
We also support OEM projects and system integration, providing consistent product design, technical documentation, and long-term supply to ensure smooth integration and reliable operation throughout the project lifecycle.
Full digital electrodes convert analog signals into digital signals directly at the sensor head.
Advantages include:
Reduced signal attenuation over long cable distances
Improved resistance to electromagnetic interference
More stable signal transmission
Enhanced compatibility with digital communication systems
This architecture is particularly beneficial in industrial environments with high electrical noise.
Anti-interference capability is achieved through:
Digital signal conversion at the electrode level
Shielded cable structure
Stable internal signal processing algorithms
Isolation between measurement and power circuits
By minimizing analog transmission length, the system reduces susceptibility to external electromagnetic disturbances.
Resolution refers to the smallest displayed increment (0.001 pH in this model).
Accuracy indicates the allowable measurement deviation (±0.1 pH).
High resolution enables detection of small value changes, while accuracy defines the true closeness to the actual pH value.
Both parameters should be considered when evaluating instrument suitability for specific applications.
Long-term drift may occur due to:
Electrode aging
Reference junction contamination
Temperature stress
Chemical exposure
The system supports automatic temperature compensation and high-stability digital processing to reduce drift impact.
Routine calibration and preventive electrode maintenance remain essential for sustained performance.
High resolution allows operators to observe subtle fluctuations in pH trends.
In processes requiring tight pH regulation—such as chemical dosing or neutralization control—fine resolution supports more responsive operational decisions.
However, resolution should always be evaluated alongside calibration stability and process repeatability.
Yes.
With IP68 electrode protection, 500,000-record storage capacity, and digital signal stability, the system is suitable for extended monitoring tasks in environmental and industrial projects.
For critical applications, periodic calibration planning and electrode inspection are recommended to maintain long-term reliability.
