Hydrometer, Specific Gravity, Analytical

Quick Answer: The LabEquip Analytical Specific Gravity Hydrometer is a precision, narrow-range density instrument designed for laboratory bench work where accuracy matters more than a wide measuring span. It reads specific gravity relative to water and is built for pharmaceutical, chemical, and quality-control settings that need tighter readings than a general-purpose or industrial hydrometer can offer.

Product Description

This hydrometer measures the specific gravity (density relative to water) of a liquid using the standard buoyancy principle: it floats at a depth determined by the liquid’s density, and the reading is taken at the liquid’s surface against a printed glass stem scale. The “Analytical” designation refers to its intended use — controlled laboratory analysis rather than field or bulk industrial checks — which generally calls for finer graduation spacing over a narrower span than a general-purpose instrument covers in one reading.

What Makes This Instrument Distinct

Within our specific gravity hydrometer range, this analytical-grade instrument is positioned for precision laboratory bench use, distinct from the already-listed Hydrometer, Specific Gravity, Industry (a general-purpose glass instrument suited to routine industrial checks) and the dual-scale Hydrometer, Specific Gravity/ Beaume, General Purpose. Where an industry-grade hydrometer typically favours a broader working range for general checks, an analytical instrument is intended for narrower-range, higher-precision readings, and laboratories commonly use several analytical hydrometers together, each covering a different portion of the specific gravity scale, to maintain that precision across a wider overall span. We have not independently verified the exact graduation interval or the specific gravity range printed on this particular listing’s stem — please confirm the precise range and least count with our sales team before specifying it for a tender or calibration record.

Care & Maintenance

• Handle by the top of the stem only — avoid gripping or knocking the weighted bulb.
• Rinse with clean water and dry immediately after each use to prevent residue from affecting future readings.
• Store upright in a padded case or rack, away from other glassware, to avoid chips or scratches on the graduated scale.
• Avoid sudden temperature changes when moving between samples, as thermal shock can crack the glass.
• Periodically check calibration against a known reference liquid (such as distilled water) as part of routine lab QC.

Frequently Asked Questions

What does “analytical” mean for this hydrometer?
It indicates the instrument is intended for precision laboratory bench work, generally with a narrower measuring span and finer graduation spacing than a general-purpose or industrial hydrometer.

What scale does it read?
It reads specific gravity — the density of a liquid relative to water — using a printed glass stem scale.

How is it different from the Industry-grade hydrometer you sell?
The Industry-grade hydrometer is built for general, routine industrial checks over a broader range, while this analytical instrument targets tighter, laboratory-grade precision.

Do I need more than one to cover a wide density range?
Often, yes — laboratories commonly use a set of analytical hydrometers, each covering a narrower band, to maintain precision across a wider overall specific gravity range. Confirm your exact requirement with our sales team.

What is the exact graduation interval on this listing?
We have not independently verified the precise range or graduation interval for this specific listing. Please contact our sales team at [email protected] to confirm before specifying it for a tender or calibration record.

How should I clean and store it?
Rinse and dry it after each use, handle it by the stem only, and store it upright in a padded case away from other glassware to prevent chips that could affect readings.
