UV-spectrophotometer double beam

Manufactured in the U.K., the QWS4 combines performance and reliability with exceptional value for money. This new water still incorporates a number of operational and safety features that make this still the ideal choice for your laboratory. • Output capacity 4Litres/Hour pyrogen free* single distilled water • Distillate quality complies with European Pharmacopoeia for Purified Water & A.S.T.M. Type 4. • Pyrex® glass boiler and condenser minimise potential contamination of distillate from the leaching effect of distilled water on metal components • Distillate pH5.0-6.5 • Distillate conductivity 3.0-5.0uS/cm • 3kW chromium plated heating element with 2 independent re-settable thermostats protect the still in the event of water supply failure • Easy to clean. No glassware dismantling is required • Available in 230V, 220V and 120V versions. Output capacity of 120V model is around 2.4Litres/Hour • Can wall or bench mounted • CE marked by independent testing agency • Supplied with an instruction/operating manual • All of the major components are available as spare parts *We recommend that the distillate is tested before use

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.
