SI (metric) Versions
“SI” is the French acronym for the International System of Units. DTGs with “KPA” in the part
number are intended for markets where
only SI units are permitted. Therefore, these models
only have kpa, Bar and/or mBar available.
Accuracy
20 to 100% of Full Scale: ± 0.1% of reading
0 to 20% of Full Scale: ± 0.02% of Full Scale
*0 to -14.5 PSIG: ±2% of Full Scale (where F.S. = 14.5 PSI)
Note: Accuracy specifications are for one year, and include all effects of linearity, hysteresis,
repeatability, and temperature within the specified operating temperature range. The gauge
must be exercised and re-zeroed whenever exposed to significant changes in environmental
conditions to achieve these specifications. To exercise the gauge, cycle the gauge between zero
and the pressure of interest. A properly exercised gauge will return to a perfect zero reading.
Exposure to environmental extremes of temperature, shock and/or vibration may warrant a more
frequent recertification period.
*Not specified for 2000 PSI (7000 kpa) models and higher, though all models can be safely
connected to vacuum.
