Intrinsically Safe Digital Gauge with Memory Function
LEO-Record-Ei-H2
The highly accurate, digital pressure gauge LEO-Record-H2 complements the hydrogen portfolio with a display and storage device, which can record pressure and temperature over a longer period of time. Due to the increased nickel content in the stainless steel, the device has a low embrittlement rate, which ensures a long service life. Thanks to its gold-plated membrane, H2 diffusion is reduced to a minimum.
Via the RS485 interface, the pressure gauge can be easily connected to a computer to make configurations or read out the records. With its high accuracy and safety, the LEO-Record-H2 fulfils all requirements for measuring devices in the field of hydrogen.
Intrinsically safe – suitable for use in explosive atmospheres.
