Description
JTZSE4 DIGITAL CONTROL SWITCH
Digital vacuum / pressure control switch for non-corrosive gases
Product Overview
JTZSE4
The JTZSE4 Digital Control Switch is a popular standard model for use with non-corrosive gases [compound and low pressure]. It is a compact multi-purpose compound pressure gauge specifically designed to cover negative to normal pressure. A rear mount bracket option is available.
