Three little low poly fantasy characters perfect to use for strategy tabletop games or as Dungeon and Dragons characters. Includes the Troll Spear Thrower, the Orc Skull Smasher and the Goblin Assassin. They print without support, the default size is as small as possible. If you are not sure about your printers capability or want to have them as game figures it is highly recommended to print them at 150%! More figures coming soon!Consisting simply of a surface and legs, the table is one piece

of furniture that has remained largely the same for thousands of But now, a French design duo has come up with a way to turn the humble table into a means of climate control that doesn't use any Paris-based industrial designer Jean-Sébastien Lagrange teamed up with French engineer Raphaël Ménard to create the Zero Energy Furniture table, also known as the ZEF Climatic Table. table looks like any other with the sleek design of a solid plank oak top and angled legs — but it could hold the secret to cutting energy costs by as much as 60%. “We wanted to see if it was possible to address climate and energy issues on a furniture scale,” Beneath the oak table are a series of phase-changing materials (PCMs) placed between the wood and anodized aluminum bottom. materials soften when the surrounding room reaches around 71 degrees, absorbing the excess heat, and then harden once the temperature dips back below 71 degrees, releasing the trapped

heat with the help of the aluminum and causing a noticeable change in the room’s temperature.air conditioning unit specials That means the table is essentially working like a “thermalheat pump units prices sponge,” as Lagrange and Ménard put it, sucking up excess heatthe air handling unit and then releasing it once the room becomes cool enough. According to the inventors, the table has the potential to reduce heating needs by as much as 60% and cooling demands by as much as 30%, which could save a lot of money as well as energy. It’s a feat of engineering that makes the most sense in homes that don't have climate control. In climates where the temperature can drastically swing from hot to cold in short spans of time, the ZEF Climatic Table

For example, if a room heats up on a sunny day and then the temperature drops at night, the ZEF table would make the climate in that room more consistent. The ZEF table works best in rooms that undergo significant It would also be best in parts of the world where air conditioning is either undesirable — like parts of Europe where it’s thought to cause illnesses thermostat or air conditioning unit is constantly turned on, it would be fighting the ZEF table and using more energy instead of Lagrange and Ménard are planning more Zero Energy Furniture inThe pair told WIRED that they are looking into home goods as well as lighting designs in their next Find out more about the Refractometers are widely used to measure the amount of dissolved substances in solutions containing mainly sucrose. between refractive index and the amount of dry substance content is well known for sucrose and is the basis of the Brix scale which is

measure of the number of grams of sucrose present per 100 grams of(50 Brix means 50 grams of solid per 100 gms of solution) This relationship holds for a large number of similar substances and so the Brix scale is widely used in the food industry. Unfortunately the refractive index of a sugar solution changes with temperature while its solid content remains the same. refractive index at different temperatures correspond to differentManual "Abbe" refractometers do not compensate for this temperature effect and manual correction tables should be used to adjust the readings to a standard temperature. The Schmidt and Haensch range of automatic refractometers supplied by Topac measure both the refractive index and the temperature of the sample in order to evaluate the Brix value. They read out both the actual refractive index and the actual sample temperature, but they automatically correct the Brix value to what it would be at 20 degs C.

regardless of the actual sample temperature. ( In the range 15 - 40 C) The instruments come in a variety of configurations to meet the needs of laboratory , QC, research and production applications. see what you need here then please call us to discuss your The ATR C instrument (pictured above) incorporates the sample holder into the same case as theThe sample (0.3ml) is easily placed in the funnel shaped sample well which is easily removed for cleaning. are automatically compensated to 20 deg C. in the temperature range 15An optional temperature stabilized sample holder can be fitted to the ATR-C. This facilitates adjustment of the measuring temperature in the range +15 - + 40 degrees Celsius with the aid of temperature controlled circulation bath. The ATR-E is similar to the ATR-CIt is designed for routine daily use for Brix measurements with an accuracy of 0.1 Brix with a fixed sample holder. temperature controlled sample holder for the ATR-E)

The ATR S is a continuous flow through version of the above, for use as a cane sugar purity analyzer in combination with theThis unit includes a stainless steel flow through cell, vertical prism and RS232 interface. Model ATR-SW with external sample holders The ATR SW is more accurate refractometer having a resolution of 0.0001 refractive index and 0.02 Brix. The sample holder is external to the electronic unit and can be used in either the horizontal position or in a vertical position with a flow through cell andThe sample holder is fitted with recirculating temperature control circuit for stabilizing the sample temperature with recirculating fluid from a temperature controlled bath. door used in the vertical flow through version may also be hooked into the temperature control circuit providing a highly stable thermal mass all around the sample. The vertical mode of operation is very useful for monitoring a continuous flow of sample liquid.

In this case the electronics can be set up to make measurements at predetermined intervals from 1 to 99 seconds. The vertical orientation is also useful for samples where solid particles may settle during measurement - in the vertical mode such particles do not settle on the measuring Model DUR-SW High Resolution Research Digital The DUR SW is a more sophisticated digital table top unit than the ATRs above. It offers a very high precision with a resolution of 0.00001 refractive index and 0.01 Brix . powerful electronics unit makes it possible to store up to 30 different scales and allows you to program scales to suit your ownOptional scales include Brix, Oechsle, Beaume, Serum,The display includes 8 lines of 30 characters each and the software provides for sample identification, clock, and print outThe layout of the display can be changed by the user. The sample holder provides for horizontal or vertical use as described
