    Keller ECO2 Digital Manometer (300bar)

    The Keller ECO2 Digital Manometer can measure pressure from 0 to 300bar via its 7/16” UNF male connector. Measurements are accurate to ±0.5% FS and it boasts a resolution of 100mbar.

    In addition to the 7/16” connector, the Keller ECO2 also comes supplied with a G1/4” adaptor and an ‘O’ ring swivel that allows the manometer to swivel through 360˚. Pressure measurements are taken via the piezoresistive pressure transducer.

    The Keller ECO2 has a clear digital screen and shows readings in a range of units that include bar, mbar/hPa, kPa, MPa, PSI, kp/cm2. There is a min/max recording feature with a reset option and a zero function allows relative pressure measurements.

    Automatic power off helps preserve the battery and the Keller ECO2 has a battery life of 1000 hours. Solid outer casing gives the Keller ECO2 IP65-level protection from dust and water ingress.
