Appendix
Hydrogen detecting type, etc.
Applicable refrigerants
R-410A, R-407C, R-404A, R-507A, R-134a, etc.
Previous testers detected chlorine. Since HFCs do not contain chlorine, new tester detects
hydrogen.
Contains synthetic oil, therefore it can be used for piping work of every refrigerant cycle.
Offers high rust resistance and stability over long period of time.
Can be used for R-410A and R-22 units.
High pressure gauge
- 0.1 to 5.3 MPa (-76 cmHg to 53 kg/cm
Low pressure gauge
- 0.1 to 3.8 MPa (-76 cmHg to 38 kg/cm
1/4"  5/16" (2 min  2.5 min)
No oil is used in pressure test of gauges.
For prevention of contamination
