Mastercool 691234YF-MINI Refrigerant Identifier for R1234yf, Compact PASS/FAIL Analyzer
- The Mastercool 691234YF-MINI is a handheld refrigerant identifier designed to verify R1234yf purity in automotive A/C systems; it gives a PASS or FAIL reading for contaminated blends, detects air intrusion, and operates at 12 VDC with an automatic/manual calibration method.
- Features:
- Tests for R1234yf (tetrafluoropropene) refrigerant purity and issues a PASS/FAIL signal when purity drops below ~95 %; ensures technicians do not introduce substandard or mixed refrigerants.
- Detects excess air (noncondensables) or contaminants that raise pressure and reduce cooling efficiency.
- Rugged ABS housing with rubber sleeve for protection; lightweight (~0.8 kg / 2 pounds) and portable for field use.
- Operates from vehicle power (12 VDC), with approvals including UL, CE, RoHS conformity; user interface uses membrane buttons and visual indicators.

Q: What does PASS vs FAIL mean for R1234yf purity?
A: Pass means the refrigerant tested is at or above approximately 95% purity of R1234yf; Fail indicates the presence of illegal blends, air, or contaminants below that level.
Q: Can it detect air or noncondensable gases in the system?
A: Yes, the device monitors for excess air (noncondensables) and alerts when air contamination is above acceptable levels, which can affect system performance and safety.
Q: What power source does this unit use?
A: It requires a 12 VDC power supply, typically drawn from a vehicle or power adapter matching that spec.
