RPM 2000 X, 6000 X and 10000 X The Second Generation of Electronic Reversing Pressure Meters
The RPM 2000 X, 6000 X and 10000 X is a family of digital deep sea reversing pressure meters with the outer dimensions of mercury instruments. The features are:
- Replaces mercury instruments
- High resolution and accuracy
- Ranges of 2000 dbar, 6000 dbar and 10000 dbar
- Piezoresistive sensor
- Easy to read digital display
- Electronically protected against loss of sample value
- Displays mean value, standard deviation and burst samples
- Automatic offset nullbalance capability
- Easy handling
- Robust glass - titanium housing with double O-ring seals
- 10000 m depth capability
- Contains no mercury
They have the same positive features as classical unprotected reversing thermometers but without the disadvantages:
- The displayed values are the real sample values. Use of a secondary thermometer is no longer required.
- Reading of values with maximum accuracy no longer needs optical magnification.
- Automatic offset nullbalance by initialising the sample mode.
- The sampled values are protected against inadvertent further reversing.
- Displays the mean value, which is the average of sixteen individual readings of a burst series.
- For quality determination, the standard deviation is displayed and the individual measurements of the burst can be read out.
