Absolute micro-channel bi-channel test instrument


M4890 is the new and revolutionary double channel leak tester at absolute decay by ForTest. Born to be integrated on benches with high production rates, it provides a hardware that can be compared to that one of top series equipments, and with a measurement resolution up to 0,1 Pa. 

M4890 provides an innovative 2,5 “ high-resolution Oled display, a USB port for direct connection with PC (management software included) and several expansion ports to external automations, indicator lights, limit swtch, programming keyboards, etc…

The black anodized aluminium case has been designed for fixing it to a Din bar, or to a panel, or finally, by pneumatic connectors, directly on the station in order to minimize the volume under test.

Thanks to its double pneumatics, ultra fast internal valves and small testing connectors, testing time is reduced by half compared to single-channel equipments. 

Following a philosophy of fast assembling and quick start, M4890 has been designed to replace “do it yourself” testing stations, composed by pressure transducers, pneumatic groups and PLC, allowing to make a “plug and play”, without programming and installation costs; few minutes after assembling you will be fully operatives. 

M4890 can communicate via protocol whose property is of ForTest, Canbus or Modbus. 

Working scales go from -1 to 6 bar.
