Design a Calibrator Setup with Your Department’s Specific Needs in Mind! Finding the perfect combination for your department is quick and simple with the CRC-Ultra.

Supports the Connection of Many Different Combinations of Ion and PET Chambers,Well Counter, and Beta Counter. The flexible configuration of Beta Detector, Well Counter, and field upgradeable Ion and PET chambers creates an endless possibility of combinations. The CRC-Ultra can also combine both 12 atmosphere and 5 atmosphere PET chambers, and uses the same outstanding proprietary sealed and pressurized chambers.

The Choice is Yours: Create a Setup as Simple or as Broad as You Require! Whether you plan to operate a small setup or something on a grand scale, look to the future with the CRC-Ultra’s expansive capabilities. By simply connecting additional units, the CRC-Ultra can adapt to changes as quickly as your department does!

Connect Additional Remote Displays and Printers for Enhanced Functionality 

- The intelligent remote display unit is controlled by the CRC-Ultra Dose Calibrator. It switches up to (8) pre-set nuclides independ-ently for each chamber, measures bias voltage, Auto Zero, Auto Background, and performs accuracy tests. The remote can be located as far as 100 feet from the main unit. - Item #5130-2211

- The Epson roll printer (Item#5430-0058) makes an excellent companion to the CRC-Ultra. Compact and ideal in locations where space is a minimum, it uses an easily accessible ribbon cartridge that prints red or black.  The CRC-Ultra also accomodates Okidata, HP Deskjet, and Epson Stylus printers with USB interface
