Description
EKWi comparator/relay output is a laboratory balance accessory that adds comparator and relay output capability for compatible EKWi-series instruments. It is intended for setups in which weighing status needs to be signalled or switched to external devices as part of routine laboratory workflows. The accessory is supplied as one piece, with a net weight of 0,5 kg and a gross weight of 1,0 kg. Packaging measures 0,17 m in depth, 0,17 m in width and 0,2 m in height, corresponding to a packaging volume of 0,006 m³. Country of origin is Japan. This comparator/relay output unit from manufacturer A&D Instruments is covered by a one-year warranty and is grouped with laboratory materials and balance accessories. It complements precision and fine-balance installations where comparator results must be made available beyond the instrument display, without altering the core weighing hardware. Compact packaging and moderate weight simplify storage, shipment and bench-side installation beside the host balance.

Questions about EKWi Comp/Relay Output
What is this article?
EKWi Comp/Relay Output is the article on this page. Luminix Health distributes A&D for laboratory use. It sits in Balance accessories, calibration & certificates, inside Balances & scales, in Lab instruments.
These are the draft shields, the pans, the ionisers, the printers and the calibration certificates that belong to a balance. A certificate states the errors found at stated loads. It does not make a different balance correct.
A balance compares a mass with a standard. An analytical balance reads to 0.1 mg or finer and needs a draft shield and a stable bench. A precision balance is coarser and faster. A platform scale takes a heavier load. The reading is only as good as the calibration chain back to the kilogram, which is why test weights and a certificate exist. A moisture analyser is a balance with a heater: it records the loss of mass as water leaves. The unit of mass is kept by the BIPM, compared across Europe by EURAMET, and accredited by BELAC. NIST publishes the same measurement foundations.
