UV1800PC UV Visible Spectrophotometer for Boiler Feedwater
·Product description
UV1800 adopts new design of double beam ratio monitoring system with perfect optical properties. this instrument is one of the essential basic instruments for laboratory analysis.
·Features
1. It is cost-effective with two configurations of host and software control.
It has the precise double beam ratio monitoring system and reasonable design of circuit control with large screen of LCD. the host can operate scanning, transmittance, absorbance, linear regression, and auto-adjust to 0% and 100% individually. the indexes of accuracy, repeatability, linear, stray light and noise are perfect. the bandwidth of 2nm is suitable for many applications needs. the measuring process is simple and fast while the measured data are stable and reliable.
 
2. Inter setting of SCM technique and qualitative &quantitative analysis software. 
It has the functions of automatic control, data acquisition and processing, spectral measurement, dynamic measurement, quantitative analysis, DNA detection and spectral scanning. the software has pull-down menu function for convenient operation.
 
3. Advanced circuit control system
Advanced circuit control system gets the high stability and low noise for the instrument. 
 
4. the injection chamber can be disassembled.
It has disassembled injection chamber with automatic four-connecting injection cells for changing different accessories according to user's analytic needs. Many accessories for choosing for different applications, such as reflective injection rack, solid injection rack, constant temperature bath and auto-injector.
 
5. Design of spacious and open light chamber is convenient to change the light source.
 
6. Stable and reliable performance
the key components are imported. Environment-friendly deuterium lamp (no ozone) of Japan Hamamatsu and the long life tungsten lamp of OSRAM with 2000h using-life and convenient to be replaced.
 
7. Nine isolated scanning curves and 9 working curves can be stored. 
 
8. Large screen display 
Six inches lattice backlit digital LCD has the distinguishability of 320*240.
