The PG-100B series inherits many of the features from the PG-100N series such as Si chip for excellent stability, easy one-handed operation, large 3½ digit LCD display, long battery life, automatic power off, one-touch zero-point calibration, and analog output. On top of these features, PG-100B uses SUS316L stainless steel diaphragm for pressure sensing which allows the PG-100B series to measure both gas and liquid pressure. Pressure units can be changed in selected models.
