Knick Portamess® 911 Oxy with Knick SE 302 oxygen sensor
Portamess® 911 Oxy
The basic unit for the mobile oxygen measurement. Clearly. Uncomplicated.
The facts:
* Measured with flow free oxygen sensors; stirrer is not required
* Automatic calibration on air (in the device's calibration vessel) with one button operation
* Automatic correction for temperature and pressure influences
* Permanent polarization of the sensor for measurement of immediate
* Sensors maintenance
* Measurements in the laboratory / field sensor SE 302 - immersion measurements with SE 303
* Comparison or control measurements of process sensors with adapter cable
* Possibility to enter the salt content to correct the solubility
* Zero point calibration of sensors articulated not necessary, but possible for sensors with offset
* Calibration timer
* Simultaneous display of temperature and oxygen Size
* Display of oxygen saturation index, or oxygen concentration
* Power Up with display control
* Low battery warning
* 1000 hours with only 3 AA batteries (AA)
* Shutdown (polarization voltage of the sensor is not turned off)
* 200 values may be stored with date and time
* Data Logger
