Double Beam Balance
Tuesday, April 22nd, 2014Harvard Trip Balance,Dual Beam Balance Scale,Dual Beam Balance balance
Tuesday, April 22nd, 2014-
Two Stainless Steel Platforms
This mechanical scale has two durable stainless steel weighing platforms for comparison weighing in labs and classrooms. Unlike gold or silver, stainless steel doesn’t scratch easily and keeps its shine without rusting or tarnishing.

Double Weighing Beams
This beam balance has two weight beams for more precise weighing. The larger beam measures to 200 grams with 10 gram resolution and the smaller to 10 grams with 0.1 gram resolution.
-
Tare Poise
This mechanical balance comes equipped with a tare poise. This will let ya zero the weight of a separate container without the need for additional counter weights. You can tare up to 225 grams of weight with this beam balance.
-
Zero Adjust Knob
Before you start weighing with the Harvard 1560SD you can make sure it’s set to zero by using the zero knob on the side of the balance. This can help assure you’re getting the most accurate weight readings from this Harvard Trip balance.
-
Magnetic Damping
You don’t have to worry about this balance bouncing around taking forever to stabilize. Ohaus was smart with this mechanical balance and designed it with a magnetic damping system to make weighing and reading your weights quick and painless.

Instructions on use
- The triple beam balance is used to measure masses very precisely; the reading error is 0.05 gram.
- With the pan empty, move the three sliders on the three beams to their leftmost positions, so that the balance reads zero. If the indicator on the far right is not aligned with the fixed mark, then calibrate the balance by turning the set screw on the left under the pan.
- Once the balance has been calibrated, place the object to be measured on the pan.
- Move the 100 gram slider along the beam to the right until the indicator drops below the fixed mark. The notched position immediately to the left of this point indicates the number of hundreds of grams.
- Now move the 10 gram slider along the beam to the right until the indicator drops below the fixed mark. The notched position immediately to the left of this point indicates the number of tens of grams.
- The beam in front is not notched; the slider can move anywhere along the beam. The boldface numbers on this beam are grams and the tick marks between the boldface numbers indicate tenths of grams.
- To find the mass of the object on the pan, simple add the numbers from the three beams.
- As with a ruler, it is possible to read the front scale to the nearest half tick mark.
Newton Spring Scale
Tuesday, April 22nd, 2014Balances measure mass.
Scales calibrated in kilograms are only done so for convenience, because we often use them to weigh in Earth standard gravity, and what we really want is the mass, but we cheat by using the scale instead of the balance.
Newtons aren’t a very popular unit in common use outside the study of physics…unfortunately, and so is the distinction of mass vs weight unpopular for one to understand.
For this reason, a 1 kg reading on a spring scale refers to 9.8 Newtons of tension, and it scales proportionally. This refers to the TENSION force with which the spring scale pulls on something.
If used to measure friction force, it is only done so indirectly. Because the target object is, in a good experiment, pulled at constant velocity, forces on it add up to zero, and as such, the tension need fully oppose the friction, should the scale be pulled horizontally and should the surface be flat.

Convenient Weight Marker
When ya give this spring scale a tug, the weight marker will slide to the appropriate weight and stay there until ya move it back to zero. This will help ya out when you’re weighing items that are a little on the heavy side. Load, weigh, unload, check your weights…it’s really simple.

This Thing Sure Is Durable
This mechanical scale was built to last. Inside the corrosion resistant housing you’ll find stainless steel components that are attached to the stainless steel weighing hook and hanger. Whether ya want to use this as a fishing scale, hunting scale, bow scale, or just a great general purpose scale, you’re good to go with this Halsun.

Quadruple Beam Balance
Wednesday, April 16th, 2014A quadruple-beam balance is a handy laboratory tool to have when you need to weigh small items to a hundredth-gram precision. The beams are horizontal metal rails that hold sliding counterweights, starting with 100 grams and going down to a tenth-gram. The first beam is furthest back from the user; it holds the 100-gram mass, the second is closer, having the 10-gram, and so on. The tenth-gram beam is marked in .01-gram increments. An adjustable weighted screw on the left lets you precisely zero the scale. On the right is a tilting indicator. It’s vertically centered when the scale’s in balance, otherwise it’s over-or under-balanced.
