Quart X-ray field meter and the high-precision kV / mass meters are designed to be able to measure with simple operation without trouble of the inspector.
It can be used without troublesome and complicated presetting, and very high accuracy measurement value can be acquired.
X-ray field & Fan beam meter
■ QUART nonius
QUART nonius is a sophisticated measuring instrument for easily checking the geometrical characteristics of X-ray irradiation field and X-ray. It can be used in both analog and digital systems and can be used for analysis of X-ray fan beam characteristics of CT and dental equipment. Measurement accuracy is very high, and its tolerance is only 0.1 mm. Because of its excellent precision and resolution properties, enhanced product research has validated the nonius to be suitable for QA application in Radiation Therapy. Measurement results are transferred to the PC in real time, and the data is visualized in an easy-to-understand manner by the nonius software.
It can be connected to any PC as long as it uses Windows OS. Also, it can measure the position and width of the X-ray of the fan beam, as well as dose.
- optional QUART bridge holder available as an accessory
- nonius is equipped with a USB cable and comes with the associated software & a compact carrying case.
[How to use] Very easy to use!
① Connect the device via USB to a Laptop or Tablet PC
(Windows OS required).
② Position the head unit at the respective position.
③ Use light field or a reference point for alignment.
④ Trigger the QA/QC exposure.
⑤ Immediately evaluate the results.

The high-precision kV / mAs meters
■ QUART didoMAS
QUART didoMAS is a high precision meter that can be used with almost all X-ray equipment from general imaging to mammography. The measurement range is set automatically, and presetting for measurement time and parameters is unnecessary.
A customized cable for the connection and detector head and circuit are included in the set.
- The mA is refreshed and displayed every second.
- One charge, 80 hours of continuous use.
- Recharging the meter until full takes only between 3 – 4 hours
- Low battery warning

■ MAS１
MAS 1 can measure electric current from various X-rays and display integrated type ammeter. Since this meter has an AC / DC automatic detection function, resetting manually is not needed. Also, since the display of the meter shows all the information at one time, one irradiation is enough.
- measures electric current from any x-ray: single phase / full wave / multiphase /DC
- use for medical or dental x-rays, digital x-ray
- battery operated, built in measurement of battery
- displays mA, mAs and exposure time for each reading
