A great deal of information lies hidden behind the vibrating needle of a typical pressure gauge. Is the TEV valve modulating properly, or is there liquid flooding back in the system?

Digi-Cool offers unprecedented diagnostic power with the Digital Refrigeration System Analyzer (DRSA). The patented pressure bar graphs allow you to see pressure dynamics intuitively for quick diagnosis. Automatic saturation, subcooling and superheat readings mean no more wallet cards. Conceived by a technician with modern engineering, the unit will endure years of field use.

The new DRSA-1100 features an integrated temperature probe to automatically calculate superheat and subcooling, and pressure extremes monitoring for simple pressure controls set-up, for even greater convenience during start-ups.
