PendoTECH Single Use Conductivity Sensors are manufactured in an FDA Registered, ISO 13485 certified facility and each sensor is tested prior to release to ensure accuracy and to determine its unique cell constant
1 to 5, cell constant
recognition:automatic, temperature compensation: 0.
Features include automatic or manual temperature compensation, automatic conductivity cell constant
recognition with auto ranging, and up to five-point calibration.
By employing an appropriate cell constant, c, it is possible to determine the specific electrical conductivity from the resistance and temperature measurements (American Public Health Association 1985) as:
25] is electrical conductivity of the sample (dS/m) at 25[degrees]C; c is cell constant (1/m), which represents the specific resistance measured by the electrodes; T is temperature of the measurements ([degrees]C); R is measured resistance of the sample ([OMEGA]), which may be expressed as R = V/I; V is potential difference between 2 inner electrodes (V); and I is current (A).
The CLS 15 sensors are calibrated with ASTM-produced standards and delivered with NIST certificate and precision cell constant
The enzyme maintains different ion concentrations on either side of a membrane, a crucial factor in keeping the volume of a cell constant
and propagating nerve signals.
The software packages available with the DSC will automatically calculate the cell constant
as part of the calibration routine, and then use this value during subsequent experimentation.
it is necessary to keep the temperature of the cell constant
Typical examples of the NRFs are given that have been derived from cell constants
published in recent issues of Acta Crystallographica Section E.
Assuming we had a periodic low-symmetry crystal, we searched unsuccessfully to fi t the data with cell constants
With cell constants
suitable for high purity water through to plant water, their Model 403 conductivity sensor is manufactured from FDA-compliant materials and is avaidable with 1.
