Instrava — Engineered for Intelligent Analytical Control.
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.
pH electrodes generate extremely weak millivolt signals.
A high input impedance (≤1×10¹²Ω) prevents signal loading effects that could distort the electrode potential. Combined with ultra-low input current (≤2×10⁻¹²A), the design ensures signal integrity, faster stabilization, and improved measurement accuracy in high-resistance samples.
How does the instrument maintain long-term measurement stability (±0.01 pH / 3h)?
Bluetooth communication is designed for short-range controlled environments.
Data transmission can be restricted to authorized devices and is typically used for:
Wireless printing
Mobile data viewing
Temporary field documentation
For regulated laboratory data archiving, USB and RS232 wired transfer remain the primary traceable communication methods.
The smart electrode diagnostic system evaluates calibration slope and offset values after each calibration cycle.
It helps identify:
Electrode aging
Membrane contamination
Calibration instability
This preventive diagnostic approach reduces measurement uncertainty before formal testing begins.
The system automatically recognizes 25 predefined buffers across Europe & USA, NIST, and China standards.
Automatic identification reduces human input error, ensures correct buffer matching, and improves multi-point calibration consistency.
The embedded microprocessor coordinates:
1000-set structured data storage
Timestamp tracking
Data filtering and recall
USB export (Excel-compatible format)
System self-diagnosis and firmware logic control
This integrated architecture supports traceable and organized laboratory workflows.
