Delmer LD 2 Microbalance – 2 g Capacity, 1 µg Readability
The Delmer LD 2 is a laboratory microbalance listed with a 2 g maximum capacity and 1 µg (0.001 mg) readability. It is designed for specialist low-mass weighing where the method requires very small sample measurements and the balance's verified performance is suitable for the required tolerance. The listed repeatability is ±1 µg and linearity is ±3 µg; the pan diameter is 15 mm.

How to assess suitability
Do not select a microbalance on readability alone. Compare the smallest sample mass, allowable measurement error, repeatability, linearity, uncertainty, environmental conditions and required records. Use a stable, level, low-vibration bench; minimise drafts, static and temperature changes; and follow the manufacturer's handling and calibration instructions.
A product listing does not establish USP, GMP, GLP or legal-metrology certification. For regulated laboratory use, confirm the instrument's documentation and qualify it within the applicable quality system. Commercial precious-metal transactions may have separate local legal-metrology requirements.
LD 2 or LD 5?
The LD 2 is listed for a maximum of 2 g and ±1 µg repeatability; the LD 5 provides a listed 5 g capacity and ±2 µg repeatability. Both list 1 µg readability. Choose against the sample range and validated method requirements, not capacity or display increment alone.
Frequently asked questions
What does 1 µg readability mean? The display increments in 1 µg steps. This is not a guarantee of 1 µg accuracy or uncertainty.
Can the LD 2 be used for pharmaceutical weighing? It may be suitable when its verified performance meets the method and required qualification, calibration and documentation are completed. Confirm suitability before use.
What information should I provide for a recommendation? Share the smallest and largest sample mass, required tolerance, application, destination country, documentation needs and interface requirements.
