Series LFDPTG-1
Bottom Entry Combination
Pressure/Temperature Gauges
Dial Sizes: 3" (80mm)
Series LFDPTG-1 Combination Pressure and Temperature
Gauges are used in commercial, residential, and institutional
HVAC applications. These gauges are bottom-entry type
models with black enamel steel cases, Kostil Polymer windows,
1
/2" NPT connections, copper alloy Bourdon tube
pressure elements, and bimetal spiral springs. The LFDPTG-1
features Lead Free* construction to comply with Lead Free*
installation requirements. Accuracy is ASME
, Type B. The Series
LFDPTG-1 gauges are available in various pressure rating
scales. The dual pressure scale features PSI and kPa mea-
surements. The dual temperature scale features ºF and ºC
measurements.
