Description

A galvanometer is modified to act as a voltmeter by connecting a high resistance (multiplier) in series, increasing its voltage measuring range. For ammeter conversion, a low resistance (shunt) is added in parallel, allowing the instrument to read higher currents safely. Apparatus Design: The core unit contains a moving-coil galvanometer with terminals for easy addition of external resistors. Supplied with a set of precision multiplier resistances (for voltmeter conversion) and shunt resistances (for ammeter conversion). Clearly marked and robust terminals or switches allow for quick reconfiguration between voltmeter and ammeter modes. Operation: To use as a voltmeter, the multiplier resistor is connected in series with the galvanometer—calibration is done for a specific voltage range. For ammeter function, the shunt is placed in parallel—calibration is done for a specific maximum current range. Scales and circuit arrangements are often provided to illustrate both connections in a laboratory setting. This multifunctional apparatus is ideal for practical demonstrations of meter conversions in physics and electronics labs, directly supporting concepts of series and parallel resistance behavior in measurement applications.

Ferrous Ammonium Sulphate Extra Pure (also known as Ammonium Iron(II) Sulfate Hexahydrate or Mohr's Salt) is a pale green to blue-green crystalline solid with the chemical formula FeSO4(NH4)2SO4·6H2O. It is supplied in extra pure grade with high chemical purity, typically 98.5% and above, suitable for analytical and research applications requiring precise and reliable chemical reagents.​ Description for Website Ferrous Ammonium Sulphate Extra Pure is a high-purity crystalline compound of ammonium, iron(II), and sulfate ions, stabilized as a hexahydrate. It is widely used as a primary standard in analytical chemistry for redox titrations due to its stability against oxidation compared to regular iron(II) salts. Its light blue-green crystals are odorless and dissolve readily in water. This reagent is also utilized in dosimetry for measuring gamma radiation exposure, nanomaterials synthesis, and medical applications for iron deficiency treatment.​ Key Features Chemical formula: FeSO4(NH4)2SO4·6H2O Appearance: Pale green to blue-green crystalline powder or crystals Purity: Extra pure grade (typically ≥98.5%) Solubility: Highly soluble in water; stable in air due to ammonium sulfate stabilization Applications: Analytical reagent for redox titrations, primary standard, dosimetry, nanomaterial synthesis, and medical use as an iron supplement Handling: Store in a cool, dry place protected from light; sensitive to air oxidation but more stable than simple ferrous sulfate​ Safety and Stability Extra pure ferrous ammonium sulfate is stable under recommended storage conditions but is sensitive to light and air over long periods. Proper storage and handling practices are recommended to maintain reagent quality.​ This description provides a professional summary suitable for product listings, catalogs, or websites targeting laboratory and industrial customers who require high-purity ferrous ammonium sulfate for precise chemical applications.​
