This contains everything you need to calculate or graph data in the lab. For example, compute pH vs Temperature calibration curves with ease! It also features safety precautions and can be used as a safety procedure checklist for labs of any size. This data book also includes cutsheets that will help save time and keep paperwork organized and tidy. The data book is divided into the following sections: Advantages: Faster, more accurate readings with increased precision and accuracy. Greater flexibility with scales and instruments that can be used with the precision balances. More detailed, allow the recording of more information for easier calculations and analysis. The maximum load is greater. Better designed balance to take advantage of larger weighing platens etc. Disadvantages: Balance size is substantially larger due to increased length and width. Solid bottom covers can cause problems if they are not perfectly flat or if there are "lumps" underneath them (e.g., warped lab benches). Some disadvantages may be overcome by better design, but perhaps at added cost for this feature. Some of the disadvantages are inherent in balances of any type. Other disadvantages may be less significant depending on application. Where applicable, the advantages or disadvantages listed below may be used to help determine if a spring or electronic balance is a better fit for a particular application. Generally, electronic balances have a larger capacity for a given size than spring scales. Electronic balances more closely approximate the theoretical ideal of an infinitely sensitive balance with no moving parts and no friction. Electronic balances have greater accuracy and repeatability than spring scales. They more closely approximate true mass rather than force (weight) with springs and levers that increase errors in force (weight) measurements as the lever distance increases from the fulcrum point. Electronic balances are more expensive than spring scales. Most electronic balances are less durable than spring scales because of their high sensitivity to shock. The more sensitive electronic components are also more easily damaged if dropped, banged on the lab bench top, or impacted by other lab equipment. Spring scales offer the most options for sizes and capacities for a given model size. They may be less expensive than equivalent capacity (g x range) electronic balances. They do not require calibration or maintenance like electronic balances, although you still need to check them periodically (e.g., monthly). Spring scales are generally available with larger capacities up to 2000 kg (4200 lbs). Most spring scales come with mounting hardware for permanent installation (e. g., wall hangers, clamp mounts, etc.), but some may be temporarily mounted (e.g., on a lab bench). Spring scales are generally less expensive than comparable capacity (g x range) electronic balances. Scale accuracy is generally dependent upon the spring design used. The smaller the range of the spring scale, the more impact it will have on accuracy due to friction and temperature changes. Accuracy can be improved by adding new springs to an existing scale or by changing the torsion balance taper of that scale's balance arm.
