The Ultima ID R1234yf Refrigerant Analyzer will provide a fast, easy and accurate means to determine refrigerant purity in refrigerant storage cylinders or directly in vehicle air conditioning systems. The instrument utilizes non-dispersive infrared (NDIR) technology to determine the weight concentration of R1234yf or R134a refrigerant. Acceptable refrigerant purity as it relates to this instrument, has been defined by the SAE as a refrigerant mixture that contains 98.0%, or greater of R1234yf or R134a, by weight.
The instrument is supplied complete with an R1234yf sample hose, an R134a sample hose, a 100- 240 VAC power transformer, built in Lithium Iron Phosphate battery, thermal printer and all required
plumbing housed within a rugged, portable, storage case.
Sample gas is admitted into the instrument through the supplied sample hose and presented to the
sensing device. The instrument provides the user with a digital display of refrigerant purity. The instrument only considers the weights of the refrigerant and contaminates in the total mixture. Air is
measured, and displayed, separately. Other contents such as refrigerant oil and dye are not
considered contaminants.
The instrument interfaces with the user via a LCD graphic display, status indicator lamps, and push
button communication switches. Alarm indications are provided to alert of instrument fault conditions or contaminated refrigerant presence.
Control Panel
The Control Panel serves as the main user interface. The Control Panel features three soft key
buttons that change their function as the instrument changes modes. The current function for each
button is displayed above the Soft Key Buttons on the LCD graphic display. Red and Green LED’s
at the top of the Control Panel are used for visual status indications.

Software Updates
From time to time, software updates may be made available to improve operating performance
or add additional features. Some updates will be provided at no charge to implement operating efficiencies while others will be optional, paid upgrades, to add new refrigerants etc. Many of the updates can be completed by the user; however some will require the instrument to be returned to the factory for new gas calibrations.
The Ultima ID Pro™ has a USB update port located on the Back Panel Connections. This port should not be used for any other purpose other than to install factory updates using the factory USB drive.
Back Panel Connections
The connections located on the back panel are illustrated below.
