1. Germany TESTS TEST****4H2 gas transmitter features as follows: Standard two-wire ***0mA current signal output，with alarm control unit or DCS (distributed control systems) Large screen multi-parameter LCD display，display the gas concentration, type, unit, percent and working condition directly. Plug and Play, intelligent sensor of international standard No field calibration for changing sensor，automatic recognition of sensor’s essential parameter. Automatic recognition of sensor fault and display on site，at the same time outputting the corresponding current fault signal. Full range temperature digital compensation automatic tracking to ensure the accurate measurement The standard three of the machine is to make the single-person and single-site maintenance come true Standard PDA intelligent user software is used to achieve single-person and single-site set maintenance. Set maintenance does not affect control unit Measure range：****0, **0, **0, ***0, ***0, ***0, ****0, ****0, ****0ppm 2.
