Robinair 11910/11920
Digital Gauges
Calibrated to measure 17 different
refrigerants (R12, R22, R123, R124,
R134a, R401A, R401B, R402A, R402B,
R404A, R407C, R408A, R409A, R410A,
R502, R507, R508B) these accurate
gauges allow you to choose the
temperature (°F or °C) and pressure
units (PSI, bar, kPa and kg/cm3) your
most comfortable using. The low side
gauge has a pressure scale of 30
inHg VAC to 250 psig and the high
side gauge has a pressure scale of
0 to 800 psig. Gauges come with a
backlight to enhance the view and
make the gauges easy to see in low
light conditions.
• Includes profiles for 17 common
refrigerants.
• Detects vacuums in "Hg.
• Selectable temperature and pressure
units of measure.
• Easy to read LCD screen with
large digits.
• Automatic shutdown after 15
minutes of inactivity.
• Low battery indicator.
