precision pressure gauge

compact outline structure, one-hand operation, especially suitable for the field, narrow place to use.advanced microprocessors, timely access the date change of built-in sensor, have continuous correction to zero, linear and temperature drift of the instrument, assurance the instrument have high precision in a long time.use micro-power devices and large-capacity Ni-Mh rechargeable (Lithium) battery, and the instrument can continuous working in a long time in the wild places without electricity.the instrument compact structure, the figures show with clear and visual.imported chassis, extraction and inesrtion style external battery, can be change at random.multi-use of one machine, with an optional of many kinds of digital modules, and wide measuring range.
