3-1/8" (80 mm) DRY MANIFOLD GAUGES (°F and °C)
RED, BLUE AND BLACK With 1% accuracy (Class 1) calibration
Large 3-1/8" gauges are housed in a red or blue steel case
with front recalibrator screw. High visibility colored temperature
scales are easy to read through the full view polycarbonate crystal.
™
• Flutterless
needle pulsation
• Brass gauge movement
• Copper alloy Bourdon tube
• 1/8" NPT Male connection
• Calibrated to 1% accuracy
• Color-coded red for pressure and blue for compound
• Color-coded refrigerant types
When a gauge has a RETARD zone, full scale is considered to
be the last marked reading prior to entering the RETARD zone.
For example, this gauge has a full scale reading of 120 psi.
Gauge accuracy is not specifi ed in the RETARD zone.

gauges are 1/8" NPT Male bottom connection.
• Larger to show vacuum more accurately in inches of mercury
and Torr (or millibar)
CAUTION: Vacuum gauges must be handled carefully.
Dropping, pressurizing and rough handling reduce their life.

With dual scale
Ammonia gauges are designed for use on manifolds and as
permanent gauges on any system or equipment charged with
ammonia. The Bourdon tube is made of 316 stainless. The dials
show dual temperature and pressure scales. All gauges are equipped
with restrictors to protect the gauges against pulsating pressure.
