Laboratory Accuracy Everywhere You Need to Measure
Unmatched Capabilities in a Fully Portable Density Meter
Temperature Controlled Measurements at 20° and 25°C
The problem with most handheld Density Meters is they drift because they do not control temperature. Density Meter measurements are highly sensitive to temperature and mathematically correcting for temperature may not be good enough for some applications. Only temperature control will result in the accuracy many users require.
The Rudolph DDM 29 utilizes powerful and compact Peltier technology. Control of the sample temperature for precise heating and cooling to ensure stable and accurate measurements at either 20 or 25°C.
Rugged Stainless Steel Double U-Tube for unmatched accuracy, durability, and weight reduction
The Rudolph DDM29 uses a 316 Stainless Steel, Double U-Tube instead of a simple glass U-Tube. This new design is durable and corrosion resistant. Stainless Steel is preferable for customers who are tired of replacing glass U-Tubes in other handheld brands.
The Double U-Tube design allows for handheld accuracy and rapid measurement speed. Demonstrating 3 decimal place measurement readings in 30 seconds, and 4 decimal measurements in 60 seconds.
User friendly GUI and Bright, Back Lit,Touch Screen Display
Extremely easy to use Graphic User Interface (GUI) and the availability of 10 different Languages on a brightly lit 7 inch(128mm) touch screen makes this the most User Friendly Density Meter in the market today. The interface is a bright LED touchscreen, with a large easy to navigate GUI. No more difficulties reading measurements in bright or dark environments.
Portability and Flexibility
TheDDM29 is powered by a Lithium-Ion battery that is easily recharged, your DDM29 is ready to go everywhere you need to make measurements. This might be at the loading dock when receiving incoming raw goods or out on a distillery floor. The Lithium Ion battery can be charged in approximately 2 hours providing up to 4 hours of constant measurements under heavy usage or 8 hours of normal usage. Included is a Charging Station for convenient stationary charging.
Laboratory Accuracy – Everywhere You Need to Measure
Most Handheld Density Meters use temperature correction and publish 2 or 3 digit accuracy which is very prone to drift. The DDM29 uses Peltier Temperature Control, which eliminates drift and provides accuracy to the 4th decimal place. Laboratory accuracy in the DDM29 reduces testing of materials in the main Lab. Testing can now be done accurately in the receiving dock, formulations area, or where ever measurements are needed.
Flexible Method Management
Factory installed measurement methods cover a wide group of industries and applications. The DDM29 is factory configured with over 50 density and concentration tables, such as Brix, %Alcohol, API, and most common chemicals. Additional tables, polynomials, and formulas may be added.
Essential Oils
Chemicals
Beer, wort, and fermentation monitoring
Raw material soft drink monitoring
Monomers, Polymers and Elastometers
Pharmaceutical raw materials and finished products
A measurement method is created exactly for unique measurement applications. You may use Concentration Tables, Formulas and Polynomials to match the measurement methods used in your laboratory or field application.
