Advanced mass comparator for precise weight calibration in metrology labs.
The newest line of Radwag mass comparators enables adjusting mass standards and weights according to the OIML recommendations (R-111) from 1mg to 5 g in class E1 and lower.
Mass comparators are used for both, ensuring traceability of mass measurements and verification of weights in accordance with the principles of legal metrology. RADWAG Mass Comparators have gained recognition among Accredited Calibration Laboratories in many countries.
The standard equipment of the UYA 5Y.KO mass comparator is an anti-draft chamber eliminating imperfect conditions in weighing rooms (air drafts). The mass comparator is placed inside the anti-draft chamber. Sliding side panes enable easy access to the weighing chamber.
Mass comparator UYA 5Y.KO series, comprises two components. One of them holds the electronic module, and the other precise mechanical measuring system. Such solution guarantees elimination of temperature influence (warming of electronic elements) on the comparator's indications. The comparator features an aesthetic, cylindrically shaped weighing chamber with glass draft shield and automatic door opening system. All elements of the weighing chamber are manufactured from glass or metal to minimize the influence of electrostatic charges on the measuring result.
CAUTION: In order to carry out the weighing process by means of microbalance and ultra-microbalances correctly, it is necessary to prepare the workstation and to operate the device as required. Usage and installation guidelines are to found in the following document: Installation and usage conditions for ultra-microbalances and microbalances.
€24,146 sits above most mass comparators here. The middle half of the 134 with a price runs from €432 to €23,103.
Lab equipment markets are fragmented. Buyers spend weeks calling distributors, comparing quotes, and verifying supplier reliability. Sellers struggle to reach global research labs.
We built Questpair to fix this. Every supplier on the platform is verified before listing. Every quote you receive comes from a real, vetted seller. AI prepares your case in minutes, then a real specialist takes over.
We're an independent team based in The Netherlands, working with research labs and procurement teams across Europe and worldwide.
With a service contract, ten to fifteen years is normal for most benchtop instruments. Detectors and pumps are the parts that wear first.
Often, yes. Verified suppliers frequently work with service partners converting the instrument. If applicable, we can list servicing options alongside the offer.
Ask a scientist through the request button. Parts are often available even when the instrument itself is discontinued.
Two to six weeks, depending on refurbishment scope and whether calibration is included.
We ship to 38 countries. Crating and customs handling are quoted with the instrument.
Tell us what you need and a scientist finds it for you, usually within the hour.
