The H2000 Plus is a compact and robust instrument that pinpoints extremely small leaks using hydrogen as a trace gas. The auto ranging feature of the unit automatically adjusts the sensitivity to the situation, allowing operators to scan large areas and pinpoint leaks without ever touching a button. In addition, it provides bi-directional network communications for retrieval and download of settings. The H2000 Plus can also be fully controlled by a PC or PLC. The device features a standard hand-held and maintenance-free microelectronic probe that requires no sample suction so dust contamination is prevented.
