Description by the supplier

RADWAG-manufactured AVK-1000 automatic vacuum mass comparator is intended for national metrological institutes that transfer and maintain the national reference mass standard of 1 kg.


The comparator is intended for weighing mass standards and silicone spheres of 100 mm diameter. It enables comparison of up to 6 prototypes of max 1kg mass. The repeatability of the process is of 0.3 µg and readability of d = 0.1 µg.


A specially designed vacuum chamber enables carrying out measurements in a vacuum of 10-6 mbar capacity or in atmosphere containing noble gases.


AVK-1000 is equipped with suspended weighing pan that eliminates eccentricity errors.


Standard version of the mass comparator features thermo-hygro-barometer for testing ambient conditions with great accuracy: pressure of 0.001hPa, humidity of 0.01% and temperature of 0.001 °C.

The comparator is also equipped with high quality vacuum gauge.


The AVK-1000 vacuum mass comparator can be equipped with the LOAD LOCK system for carrying mass standards. The system enables switching or adding artefacts without changing the atmosphere inside the main chamber. With the use of a special chamber for mass standards switching the whole process is 90% shorter.

During mass standards replacement carried out without the use of the LOAD LOCK system, the air enters the main chamber of the mass comparator. After each opening of the chamber it is necessary to pump the air out in order to obtain required vacuum value. The vacuum mass comparator needs approx. 48 hours in order to obtain vacuum that ensures measurement repeatability.


The LOAD LOCK is equipped with a high-efficiency pump system, the time of pumping the air out in order to enable opening of the valve of the main chamber is significantly shortened. The stabilization of the main chamber after replacing/adding the mass standard and closing the valve connecting the main chamber and the LOAD LOCK system takes 5 hours.


The high-quality vacuum gauges enable monitoring and comparing the vacuum value in order to determine the moment when opening the valve again and replacing the mass standard is available. A specially designed viewfinder enables monitoring of the process.


The LOAD LOCK enables switching objects of dimensions adapted to the AVK-1000 mass comparator: cylindrical mass standards of 22-95 mm diameter and silicone spheres of 40-100 mm diameter.


Supplementing the AVK-1000 vacuum mass comparator with LOAD LOCK system significantly improves the comparison performance.

Radwag UYA 6.5Y.KO  Mass Comparator

The newest line of Radwag mass comparators enables adjusting mass standards and weights according to (more) 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.

Radwag HX7.4P2.1500.H Stainless Steel Multifunctional Beam Scale-cover
Radwag HX7.4P2.1500.H Stainless Steel Multifunctional Beam Scale

HX7.4P2 H is a beam scale made of stainless steel. 4-load-cell, 2-component mechanical design stands (more) for high measurement accuracy. The weights may be loaded onto the pan using a forklift or a transporter crane, supplementary handles significantly facilitate the transport. The device has been fitted with a 7" colour display and a diode bar graph. Blinking green and red diodes show current load mass, the mass is presented in reference to the scale range or declared minimum and maximum thresholds. At the back of the housing there are hermetic connectors of RS232, RS485, USB and Ethernet communication interfaces, plus digital inputs/outputs and analogue output. This enables cooperation with external devices such as barcode scanners, printers, external displays, control buttons, light signalling towers, other controlling/signalling devices, systems for automatic process control and superior IT systems. With use of the bracket you can either place the indicator at any flat horizontal surface, or fix it to the wall adjusting the tilt respectively to suit your needs. The terminal's software allows carrying out processes such as weighing, parts counting, dosing, labelling, formulations and percent weighing. Indicator’s system of information is based on databases (users, products, weighings, packaging, formulations, customers) and ALIBI memory which guarantees stored data safety.
