Before you order
Every measurement in this category is a function of temperature, and the specification that decides whether a result is defensible is the temperature control, not the measuring range. A refractive index quoted to five decimal places on a bench held to ±0.5 °C is quoted to more places than it is worth; a viscosity measured without a thermostatted jacket is a number about the room. Where a method states a reference temperature — 20 °C for most refractometry, 25 °C for many viscosity methods — the instrument has to hold it, so ask what the temperature control is before you compare anything else.

Why we publish the standard revision, not just the number.
Testing instruments are bought against a method, and a method is written against a standard. When that standard is revised, the old number stays in circulation for years — sometimes decades — because catalogues copy each other and nobody re-checks.
Three examples currently live across this industry: ASTM D1559 for Marshall stability, withdrawn in 1998. ASTM D422 for hydrometer analysis, withdrawn in 2016. IS 13311 for non-destructive concrete testing, absorbed into the IS 516 family in 2018. All three still appear on product listings you can buy from today.
That matters commercially, not just pedantically. If your quality manual cites a withdrawn standard, a NABL assessor will raise it, and the fastest way that error enters a manual is by being copied off a supplier’s specification sheet.
On qualification: for pharmaceutical customers, the documentation is half the purchase. GMP-specification equipment differs in its contact surfaces, its control system, its printed cycle records and its IQ/OQ/PQ protocol set. Specify that requirement at enquiry stage — retrofitting it after installation costs more and delays qualification.
On site preparation: compression testing machines, ductility baths, abrasion machines and large ovens need foundations, three-phase supply, drainage or extraction. We issue the foundation drawing and utility schedule with the quotation so the civil work can run in parallel with the delivery lead time rather than after it.
