Instrava OEM/ODM
Reliable Instruments. Solutions That Fit Your Application.
Instrava is focused on delivering reliable industrial solutions through carefully curated products, application-driven optimization, and flexible customization. We select proven instruments from trusted manufacturers to ensure consistent quality, optimize solutions based on real working conditions to solve practical challenges, and provide tailored configurations to meet specific application needs.
By combining selection expertise with application understanding, Instrava helps customers reduce risk, improve efficiency, and achieve dependable results in complex industrial environments.
How do I select the appropriate pH electrode?
The instrument supports both standard glass pH electrodes and antimony electrodes.
Glass electrodes are recommended for laboratory and general water analysis.
Antimony electrodes are suitable for harsher industrial environments where mechanical strength is required.
Selection depends on process temperature, chemical composition, and mechanical conditions.
How often should calibration be performed?
For laboratory-grade accuracy, calibration should be performed:
Daily in high-precision laboratory environments
Weekly or before critical measurements in industrial applications
The instrument supports 3-point automatic calibration, ensuring improved linearity and measurement confidence.
Does the meter support automatic temperature compensation?
This model supports manual temperature compensation.
Users can input the measured sample temperature to correct pH values accordingly.
For applications with large temperature fluctuations, proper compensation is essential to maintain ±0.02 pH accuracy.
Can measurement data be exported?
Yes.
The instrument includes a USB communication interface, allowing data export to a computer for analysis, reporting, and record keeping.
It also supports internal storage of up to 256 measurement records.
What is the difference between pH mode and mV mode?
pH mode is used for acidity/alkalinity measurement.
mV mode measures electrode potential directly and is often used for ORP measurement or electrode diagnostics.
The dual-mode capability increases flexibility for electrochemical testing.
Is this meter suitable for field use?
Yes.
Powered by two AAA batteries and designed for operation between -5°C and 60°C, the device is suitable for both laboratory and on-site field measurements.
Its compact design and automatic power-off function enhance portability and energy efficiency.
