Why Sellingantiques dated this piece to THE 19TH CENTURY:
Original lid label citing the Weights and Measures Act: in use from 1826.
Engraved maker's address at 5 Charing Cross: active there until the mid-19th century.
Single-slot brass screws throughout: standard cabinet hardware before machine-made crossheads.
Fine hand-cut dovetails on the mahogany case corners: traditional early 19th-century joinery.
Gentle tarnishing and light surface marks across the brass: honest working handling.

This Independent Date Guide was compiled by Sellingantiques using its own proprietary system. It works only from the photographs shown on this page and is never told the date the dealer has declared. It is a guide, not a guarantee of age, and occasional errors can occur.

This 19th century Georgian scientific instrument is a complete mahogany cased chondrometer by Watkins & Hill of 5 Charing Cross, London, devised following an Act of Parliament on the 1st of January 1826 under George IV. The set comprises warm brown timber, a polished gold-coloured brass measuring bucket, a steel component on the graduated steelyard beam, and an original instructional label affixed to the inner lid of the hinged box, secured with visible brass hinges. The fitted wooden interior compartment contains the balance beam alongside the other loose components. Measuring 8.2 cm high, 30.5 cm wide, and 11.5 cm deep, this portable grain-density scale is suitable for display on an office desk or within a gentleman's library setting.

FAQs

A chondrometer is a specialised balance instrument created in the late eighteenth and nineteenth centuries to measure the density or weight per bushel of grain and seed samples.

These instruments were precision-machined from brass with steel pivot points, housed inside custom-fitted mahogany cases to protect the scale beam and measuring cylinder.

Authentic examples feature hand-engraved weight calibrations on a brass steelyard beam, maker inscriptions from recognized instrument builders, and printed instructional paper labels inside the lid.

Displayed open on an office desk, library bookshelf, or side table, a boxed chondrometer functions as a conversational historical curiosity and decorative accent.

Store the item in a climate-controlled room away from moisture, dust the brass components using a dry soft cloth without abrasive cleansers, and condition the mahogany timber with natural beeswax.
