Highest dependability even in harsh environmentsA rugged metal housing and internal high quality shock absorbers protect the sensitive parts of the instrument reliably against damage và minimize measurement errors caused by external influences. An easy khổng lồ replace fine-dust filter prevents contamination of the internal parts. Và last but not least: A new patented reference temperature sensor makes sure variations of the surrounding temperature vị not influence the measuring accuracy.
Highest accuracy within the shortest possible timeA new optimized measuring algorithm provides reliable results within less than 30 seconds.
Sampling & drying pumps built-inHigh operating comfort without any extra costs – no jumble of cables and tubing.
Easy selection of measuring parameters và measuring methodsIt often makes sense to lớn develop a measuring method suitable lớn measure different types of products, sometimes it is much easier & quicker khổng lồ change only one parameter without having to edit & store a complete measuring method. With the DA-645 both approaches are possible – according khổng lồ the individual preferences of the operator or the requirements of the standard operating procedures.
Minimization of error sourcesAutomatic detection of insufficient cleaning or drying prior lớn calibration & automatic alerts for regular system performance checks are just two examples of the built-in features the DA-645 mật độ trùng lặp từ khóa Meter offers to lớn ensure reliable và traceable results.
API degree or gravity, Brix, AlcoholThe DA-645 density Meter shows the results directly in the desired unit. It is ideally suited for concentration determinations: Thanks to lớn a special concentration scan function it is not even necessary lớn manually input đầu vào concentration tables or formulas – the mật độ trùng lặp từ khóa Meter can teach itself how khổng lồ perform the calculation.
Well equipped for measurements at different temperaturesA calibration at one temperature covers the whole temperature range, a temperature scan function determines the volume expansion & temperature compensation coefficients automatically & heated versions of the automation units allow lớn measure products which are solid at ambient temperatures.
Energy-efficientIn addition khổng lồ a low power nguồn consumption the DA-645 features an electronic time switch clock for the built-in thermostat. This ensures permanent immediate availability without waste of electricity.
Versatile and customizableSeveral interfaces allow the connection of different peripheral devices such as keyboards, memory sticks, barcode scanners, printers, computers và different types of automation units in order to lớn increase the degree of automation, khổng lồ archive measured data, etc.
The convenient, efficient, and reliable DA-800 series is KEM’s (Kyoto Electronics Manufacturing Co., Ltd.) 6th generation line of density/specific gravity meters, inheriting technology developed with market needs firmly in mind.
Features
The DA-800 series mật độ trùng lặp từ khóa meters measure the density/specific gravity of liquid samples by employing an oscillating sensor to determine resonant frequency. What’s more, the instruments can calculate sample concentration according lớn common industry standard formulas & tables.
The instruments have a built-in temperature stabilizing function, allowing you khổng lồ measure density/specific gravity at your desired temperature.
Measurement can be conducted with as little as 1m
L of sample (if injected manually), & in as fast as 10 seconds for a temperature-stabilized sample (when viscosity correction is disabled). All models in the DA-800 range come with viscosity correction functionality as standard.
Data Integrity (DI) support functions are provided as standard to lớn help you maintain and manage your valuable data.
