Core Product Features
- Excellent stability: Adopt aluminum alloy casting base with long-term stress aging treatment to ensure the instrument maintains good stability during long-term use and guarantee the consistency of test results.
- Precise wavenumber positioning: Equipped with horizontal and rotating dual wavenumber positioning mechanism with positioning accuracy less than one wavenumber, effectively improving the accuracy of test data.
- Efficient optical & electrical system: Equipped with pulse light source, which can effectively reduce the heating intensity of the light source, help the system heat dissipation, extend the service life of instrument components and improve the reliability of the whole machine; the pre-integrated narrow-band active filter and digital phase-locked amplifier significantly improve the signal-to-noise ratio and make the instrument performance more stable.
- Real-time automatic zero adjustment: The instrument can automatically collect signals separately when the light source flashes on and off to realize real-time automatic zero adjustment, which not only simplifies the operation process but also ensures the long-term stable operation of the instrument.
- Minimal measurement error: Simulating the oil composition in water, the measurement error of standard oil with any composition is less than 3%, which can accurately match the detection needs of actual water samples and provide users with real and effective test data.
- Real-time spectrum display: Support full wavenumber measurement and display spectrum in real time, which is convenient for users to comprehensively and intuitively understand sample information and facilitate subsequent analysis work.
- Professional software support: Equipped with exclusive oil measurement software (software copyright applied), integrating spectrum scanning, analysis, calculation, storage and other functions, with convenient and efficient operation and lower user threshold.
- Flexible and convenient operation: Equipped with large-screen color LCD touch display, supporting both stand-alone independent use and computer connection operation to meet the use needs in different scenarios.
- Strong expandability: Can be upgraded to a fully automatic infrared oil analyzer. After upgrading, it can automatically complete a series of processes such as tetrachloroethylene purity inspection, extractant addition, liquid-liquid extraction, oil-water separation, animal & vegetable oil separation, oil measurement, pipeline cleaning and automatic reagent recovery, further improving detection efficiency.

The instrument operates reliably within a temperature range of 5 to 35°C and humidity below 80%. It requires a stable 220V ±20V, 50Hz ±1Hz power supply to maintain measurement accuracy.
- Environmental operating range: The analyzer must be used in an environment with temperature between 5°C and 35°C and relative humidity below 80%.
- Power supply requirements: The instrument requires a 220V ±20V, 50Hz ±1Hz power source with a maximum consumption of 40W.
How does the Atomfair IRO 739 ensure measurement accuracy of ±2% across a wide concentration range of 0.02 to 800 mg/L?
The IRO 739 achieves this accuracy through a combination of design features: a pulsed light source that reduces heating and improves stability, horizontal and rotating dual wavenumber positioning with accuracy better than one wavenumber, and a pre-integrated narrow-band active filter with digital phase-locked amplifier that enhances the signal-to-noise ratio. The instrument also simulates oil composition in water to keep measurement error for any standard oil under 3%, with a correlation coefficient R > 0.999 for the infrared non-dispersive method.
Can the Atomfair IRO 739 analyze both petroleum oils and animal/vegetable oils in the same sample without changing calibration?
Yes, the IRO 739 is designed to handle any oil composition in a single measurement. The product description states that by simulating the oil composition in water, the measurement error for standard oil with any composition is less than 3%, allowing accurate matching to actual water samples containing both petroleum and animal/vegetable oils without recalibration.
What are the power supply and environmental conditions required for reliable operation of the IRO 739?
The IRO 739 requires a power supply of 220V ±20V, 50Hz ±1Hz, consuming 40W. The operating environment must be within a temperature range of 5 to 35°C and relative humidity below 80%. These conditions are specified in the technical parameters to ensure stable performance and long-term reliability.
The Atomfair IRO 739 Infrared photometric oil analyzer delivers a compact, high-stability platform for oil-in-water determination, combining a pulse light source, dual wavenumber positioning, and real-time automatic zero adjustment to achieve a detection limit of 0.02 mg/L and measurement repeatability below 2%. Its expandability to fully automated tetrachloroethylene-based extraction workflows makes it a versatile tool for environmental and industrial laboratories, though it requires a controlled operating environment and careful handling of the extraction solvent.
Positive
- High sensitivity and precision: With a detection limit of ≤0.02 mg/L, measurement repeatability <2%, and wavenumber accuracy of ±1 cm⁻¹, the analyzer reliably quantifies trace oil concentrations in water, supporting compliance with environmental monitoring standards.
- Stable long-term operation: The aluminum alloy casting base with stress aging treatment, combined with a pulse light source and digital phase-locked amplifier, ensures baseline drift <1%/4h and consistent signal-to-noise ratio, reducing maintenance frequency and improving data reliability over extended use.
Trade-offs
- Environmental sensitivity: The instrument requires a controlled operating environment with working temperature between 5–35°C and humidity below 80%, limiting deployment in unconditioned field settings or high-humidity laboratories without additional climate control.
- Solvent handling requirement: Operation relies on tetrachloroethylene as the extraction solvent, which is a hazardous chemical requiring proper ventilation, storage, and disposal protocols, adding to laboratory safety and waste management responsibilities.
