The Cent-O-Gram with four beams, provides the ultimate in simplicity and dependability. The Cent-O-Gram balance offers the accuracy and convenience of an integrated weigh below balance while allowing students to visualize mass measurement principles. Designed with a hanging stainless steel pan system, the balance offers 10 times the readability of the Ohaus Triple Beam and Dial-O-Gram top loading balances.

For easy reading, the poise show weights through center windows, and the beams are stepped up from front to rear. The three-point beam eliminates the need for level adjustment. Zeroing is quickly achieved by means of a zero adjust knob at the end of the beam. It is built with aluminum pressure castings for the base and beam assembly, agate bearings and steel knife-edges. Everything about the Cent-O-Gram ensures a high standard of quality.

When the job calls for sensitivity to a hundredth of a gram, but the budget calls for economy, the Model 311 fits the bill perfectly.  Is was designed for precise, all-around lab work.  The unique pan and bow design allows you to handle lab vessels, powders, even small lab animals with ease.  A built-in specific gravity platform stores in the base.  To speed weighing, the magnetic damping system brings the pointer to a rest with a minimum number of swings.

Precision-ground knife edges and self aligning agate bearings provide maximum sensitivity and reproducibility.  Notched beams provide positive positioning of poise, and magnetic dampening slows oscillation. 

The Cent-O-Gram with four beams, provides the ultimate in simplicity and dependability.  For easy reading, the poise show weights through center windows, and the beams are stepped up from front to rear.

Dave's testing equipmentDavid W. Davenport has written a new report showing how three mechanical "pocket scales"-Accura, Calibrön, and Deering 10 gram -compare in accuracy to the extremely accurate Mettler AE 100 analytical balance (Swiss, electronic).  Also determine how the laboratory-quality Ohaus Dial-O-Gram 310 Model mechanical bench balance compares to the Mettler AE 100 analytical balance.  Compare and contrast all four mechanical scales for accuracy, features, and ease of use.   You'll be amazed at the results.  See the summary reportDownload Acrobat nowDownload the complete detailed report for the Dial-O-Gram 310-00 Scale in pdf format.
Ohaus Scout Pro Scales Want to go with a digital electronic balance?  Be sure to review the SPX422 (420g x 0.01g.)  The Scout comes standard with the weigh below hook for determining the specific gravity of materials.
