Determining moisture in: powders used in some manufacturing process; the food industry for ingredients like flour, powdered milk, corn meal; ingredients for ice cream; the wastewater industry for percent solids in primary and secondary sludge then the MA35 moisture balance is a great choice.
The Sartorius MA35 moisture analyzer was introduced to the market in 2006 and uses the latest weighing technology - the patented Double Lever System, or DLS, for short and is a magnetic force restoration weigh cell. The exclusive weigh sensor is only found in Sartorius balances and offers superior accuracy and repeatable weighing records with practically zero hystersis.
Sartorius is a global leader in weighing instrumentation and has been building balances since 1871. You name the brand whether it is A&D Weighing, Ohaus, Mettler-Toledo and the numerous other smaller companies and none compare to the expertise in building balances over a longer period of time. You may pay a little more for Sartorius but you are paying for their expertise and a product that works! Over the last few years we have seen many no name brands enter the moisture balance market and most are built with cheap strain gauge loadcells that are total JUNK.
The MA35 is Sartorius' replacement to the ever popular MA30. We don't have the numbers but probably the MA30 is the most commonly used moisture balance in the world for units sold. Sartorius discontinued the MA30 in 2003 and Sartorius was hoping customers would purchase the MA45 as the replacement moisture analyzer, but customer feedback changed this marketing strategy.
The MA45 moisture analyzer uses a ceramic heating element and one could consider the heating source similar to the sun where it is hottest in the center and cooler as you move outward from the center. Although the MA45 offered a mode to simulate the MA30 customers found they had to set the temperature 10 to 20 degrees higher to get corresponding results the MA30 produced for percent moisture on their samples.
The difference with the MA30 and the new MA35 is the heating element over all the other moisture balances on the market today is metal tubular and this provides more of an oven effect providing intense heat throughout the complete heating chamber thus allowing better drying to all sides of the sample (top, bottom and sides). The MA45 with the ceramic basically dries the sample on the top and more heat is applied to the center than the outer edges.
The ceramic element is still better than the halogen heating element found on most moisture balances since ceramic offers a more gradual and even ramp up temperature in the heating chamber. On the other hand halogen offer fast ramp up temperature, but it is more prone to burning and degrading your sample thus provide inconsistent and false moisture content results.
Although the metal tubular design isn't the fastest design for drying to run the percent moisture test since metal tubular takes longer to heat up over ceramic and halogen we feel it is the best method to determine moisture. Many people call and ask "how fast can I determine the moisture" when really they should be asking "how consistent and accurate are the results with this moisture analyzer over the competitor's moisture analyzer and our answer is always buy the Sartorius MA35 moisture balance.
Halogen is the cheapest heating element to manufacturer and the halogen bulbs burn out. On many models you have to send the moisture balance to the manufacturer for a costly replacement. The ceramic and metal tubular never really burn out or at least we have never had a customer call saying they needed to replace the Sartorius MA35 or MA45 heating element. Since halogen cost less these moisture analyzers are typically less than the Sartorius, but in the long run for downtime and repair cost to replace the heating element the Sartorius will cost you less to operate.
Also halogen consistently overshoots the temperature. If you set the temperature to 110°C the heat on the sample might spike to 120°C or 130°C and then stabilize back to the actual setting of 110°C. These over shots and excessive temperature on your sample may result in burning of organics and incorrect moisture results.
The metal tubular might take 120 seconds to heat to 110°C but it really is 110°C ± 1°C. So sure halogen might go to 110°C in 30 seconds but what good is it if your sample is degraded in the process.
