B-A Tough Gauge© had been developed based on the patented Tough Mode© technology by Ampere Inc. in Japan.
The Tough Mode© can heat up the grid and collector while pressure measurement in order to prevent contaminants in process environment from being deposited on the grid and the collector. In conventional B-A Gauge, the deposited contaminants shorten the lifetime of the gauge and cause inaccurate measurement.
The B-A Tough Gauge© will give longer lifetime in the environment where corrosive or organic particles involved and will be able to keep the accuracy of the measurement all through your production cycle.

TG201C is a wide range vacuum gauge from atmospheric pressure to 10-9 mbar (hPa). There is no display on itself, hence the pressure measurement data will be transmitted through its Dsub-15 port to your control system, PLC or display.
