A Spectrophotometer is an analytical instrument used to identify materials including organic polymers. Infrared spectrophotometers record the relative amount of energy as a function of the wavelength/frequency of the infrared radiation when it passes through a sample. Therefore, chemical structures of different samples will reflect differences in the IR absorption spectrum allowing for identification of a sample. Unlike a dispersive spectrometer, an FTIR spectrometer or FTIR spectrophotometer is used to simultaneously obtain spectral data of a sample. It does this by using an interferometer to collect the interferogram, also known as the raw data/signal format, which can then be translated into the infrared spectrum of the sample by means of a fourier transform algorithm. As a result there are many advantages including greater signal-to-noise ratio, high resolution, higher throughput, and a short wavelength limit. FTIR spectrometers can be used in a variety of industries including environmental, pharmaceutical, and petrochemical.

1 There are twelve tubes in two basket assembly.
2 Each test station is driven independently. Auto stop at timing point.
3 The bath liquid can achieve an even temperature.
4 A MPU is used to automatically control the temperature, time and frequency of nacelle back and forth.
5 Timing at will. The preset and real time data can be displayed alternately in time.
6 Automation: auto-test, auto-diagnose, auto-alarm.
This meter can test pH,mV and temperature in water solution,it is suitable used in lab for those units from industrial and mining enterprises,university and scientific research organ etc.
There is a microprocessor chip inside the meter and the appearance of meter looks nice with easily operation.For notable features read as follows:
1)Large LCD with white background can display both pH and temperature value a the same time.
2)It has intelligent functions for automatic calibration,automatic temperature compensation,data storage/recall,memory max. and min. value etc.
3)Automatically display the percentage of slope after finishing calibration.
4)ºC and ºF can be switched freely.
5)Equipped with Model 600 electrode holder and calibration buffer solution,which is more convenient to use.
