Intended Use

The Portavo 904 OXY is a portable 
oxygen meter. With a plain text line on 
a high-contrast LCD, operation is largely 
intuitive. The meter stands out by the 
following features:
•  Use of digital Memosens sensors
•  A detachable quiver protects the 

sensor and prevents it from drying out. 
Furthermore, it can be used for calibra-
tion. 

•  The rugged housing is made of a 

high-performance polymer. It provides 
high impact resistance and dimen-
sional stability even when exposed to 
extreme moisture.

Overview of the Portavo 904 OXY 

Quiver

•  Scratch-proof clear glass display, perfectly readable even after years
•  Very long operating time with one set of batteries (4x AA) or use of a Li-ion 

 battery for reliable operation even at high or very low operating temperatures

•  Data logger with 5000 values
•  Micro USB port for communication with Paraly SW 112 PC software for data 

evaluation of digital sensors (Memosens)

•  Sensoface icons provide single-glance information on the sensor condition 

(page 37)

•  Real-time clock and indication of battery charging level
