1Introduction to the Instrument
The instrument fully complies with the environmental standard HJ637-2018 Water Quality - Determination of Petroleum, Animal and Plant Oils - Infrared Spectrometric Method, and all performance indicators are at a high level. Adopting semiconductor refrigeration technology to ensure the stability of the detector output signal. This instrument can be used for both infrared spectrophotometry and non dispersive infrared spectrophotometry to determine oil concentration, as well as scanning sample spectra for use as a near-infrared spectrometer. This instrument can fully meet the requirements of environmental protection departments for the determination of petroleum and animal and vegetable oil content in domestic sewage and industrial wastewater, and is currently an ideal oil measuring instrument.
2Functional characteristics
1》 The product is designed according to the new standard HJ637-2018, taking into account non dispersive infrared photometry;
2》 Light source lifespan extension technology, with a lifespan of up to 100000 hours;
3》 Synchronous motor drives the chopper disc to achieve modulation of optical signals. The signal frequency is high, and after frequency selection and amplification, it is not affected by stray light;
4》 Using semiconductor detectors with long service life and utilizing semiconductor cooling technology, the signal output is more stable and not affected by changes in room temperature;
5》 Light source automatic compensation system, signal drift correction system, output signal without drift;
6》 Can be connected to a computer host for operation and use, and can also be operated offline; No need to create standard curves, no need to adjust zero points or full-scale, no need for calibration calculations,
Can directly measure samples;
7》 The operation interface displays the spectrum, measurement steps, and measurement results simultaneously. The wavenumber position and absorbance of any point in the spectrum can be read from the spectrum
Degree and transmittance.
8》 The spectrogram, measurement conditions, and measurement results can be saved to a computer or directly printed out.
