Goodbye to the Manometer Needle
KELLER AG für Druckmesstechnik now presents its fully electronic
ECO 1 manometer – an instrument that can perform all standard
measuring jobs at an exceptionally low price. As compared to its
mechanical predecessors, Keller’s digital technology offers high
resolution and excellent repeatabilty at very similar prices.
The ECO 1’s dual display updates twice every second, showing the
measured value and the minimum or maximum value attained. As
a special feature, the ECO 1 has a Zero Tare feature which allows
the user to set the zero at any pressure, so the manometer will then
always show deviations from the Zero Tare value as the actual value.
The user-friendly two-key operating system provides access to the
entire range of functions: the stored MAX/MIN can be erased and
reset to zero, or the device can be switched to continuous mode. In
continuous operating mode, the battery has capacity for up to 1400
hours. The ECO 1 electronic manometer has a standard automatic
switch-off time of about 15 minutes after the last key was pressed,
this function extends the battery life where continuous operation is
The easy-to-handle ECO 1 is available with two practice-based
measuring ranges of -1…30 bar and 0…300 bar. In the compensated temperature range from 0 to 50 °C, the economically priced standard manometer offers typical overall accuracy of 0,5 %FS (Full
Scale). The standard design features IP65 protection, and the optional protective cover means that it can also be operated reliably
outdoors in any weather conditions. This instrument is also available in an Exia ATEX approved version compliant with 94/9/EC.
The standard delivery includes a swivel pressure connection which optimises readout alignment during operation.
