recorder	Type 3066-11 (assembly yokohama, Japan) don't have to (take the paperless record instrument)
The hollow cathode lamp	Specifications complete, according to the device under test can be take into consideration the choose and buy

Main features:
Low feature-rich: computer automatically deduct blank value, deducted automatically sensitivity drift, deducted automatically baseline drift, automatic computing mean value and deviation, the working curve equation is calculated and read density automatically, automatic printing analysis report, still can undertake flame emission spectrophotometry, hydride generation atomic absorption analysis and flow injection on-line enrichment atomic absorption method.After two sensitivity to graphite furnace level, but the price is far lower than the graphite furnace.
When the operation is simple: every time after the condition set, only keys 2, can automatically read/print out the absorbance value, density and relative standard deviation.Compared with no microcomputer instrument, saved a lot of manual data processing time.
Low signal stability: USES the import high quality photomultiplier and advanced integrated circuit, the single beam optical path, light monochromator and the effective atomizer, low noise, good accuracy.Computer accurate logarithmic transformation, no temperature drift, baseline stability is good.
Low expert system: the novice teacher and consultant (only361CRTType).
Low resistance to corrosion of atomization system: atomizing chamber adopts high quality engineering plastic, burner with long life, fast heat balance type titanium burner, can achieve a long time without water cooling but determination sensitivity is not change.
Low efficient atomizer, high sensitivity and high reproducibility.
For low peak fine: special wavelength can fine tuning mechanism on the wavelength peak position accurately.
Low continuous slit: original with high resolution and continuous slit mechanism to ensure the best spectral bandwidth.
Low rust prevention performance is good, pure quality engineering plastic atomizing chamber completely solve the rust and water problem.
Good low security: equipped with secondary explosion-proof measures, even if air break, also won't accidents.
When complete: random complete, can use after purchase.A variety of form a complete set of combination of choose and buy, greatly expands the application range of this machine.

Technical indicators:
Low wavelength range:190nm～900nm
Low wavelength error value：≤±0.5nm
Low wavelength repeatability: better than0.3nm(one-way)
Low resolution: distinguish manganese double wave valley< 40% (0.2 nm spectral bandwidth）
Low baseline stability: better than0.004A/30min（Copper)
Low detection limit.< 0.007 mu g/ml (copper)
The characteristics of low concentration: < 0.04 mu g/ml / 1% (copper)

Other:
Low working power supply:220V±22V/50Hz 110V±11V/60Hz
