5.0 CLEANING, MAINTENANCE, AND DISPOSAL
The HANDI+ analyzer requires little maintenance. For best performance and accuracy, the HANDI+
should be calibrated on a frequent basis. For general use, it is recommended the HANDI+ be cali-
brated once a month on a known source of oxygen such as clean dry (compressed) air. Reference the
calibration section in this manual for more details.
If the unit becomes wet, it should be dried off immediately with a soft dry towel. The display may indi-
cate low concentrations of oxygen if the sample port of the sensor becomes wet. In this case, remove
the barbed adapter and thoroughly dry inside and out with a soft dry towel or cotton applicator tip.
Additionally, dry the face of the sensor with a cotton applicator tip and allow to air dry for one half-
hour (or until the oxygen display returns to normal). Exposure of the HANDI+ to water or extremely
high RH may result in shortened life or cause the electronic circuit or battery to fail. Disposal: Please
note the materials of construction for proper disposal. The material of the HANDI+ housing is a poly-
carbonate and ABS blend. The sensing portion of the HANDI+ contains lead and acetic acid. The
HANDI+ contains a printed circuit board and a Lithium Battery.
