2.1. The Micro 800 Meter and the Environment
The Micro 800 Meter is designed to be used outdoors and is rated to IP67, that is to say it
is waterproof but it
is not
designed for submersion. In order to prevent accidental dunking
or loss, a lanyard is supplied.
Please note that the Micro 800 Meter is only waterproof when the associated Micro
800 Probe plug is fitted. Without the plug fitted, water can enter the Meter through
the socket. Damage caused by water ingress through the socket is not covered by
your warranty.
You may notice a small hole on the rear of the unit near the socket. This is a waterproof
vent for the internal barometric sensor.
Do not poke anything into this hole!
Doing so will
cause major damage to the vent’s waterproof membrane and invalidate your warranty.
2.2. The Micro 800 Probe and the Environment
The Micro 800 Probe is designed to be fully submerged in water and is rated to IP68, that is
to say, it is rated for continual immersion.
2.3. About the Probe Sleeve
The Micro 800 Probe is constructed with a protective aluminium sleeve surrounding the
more delicate sensing electrode.
The Probe Sleeve can be easily removed by unscrewing to allow cleaning of the electrode,
however,
the Probe sleeve forms an integral, working part of the Probe’s EC
measurement system, and MUST be fitted for correct operation.
The only exception to this rule is when a DO Flowcell is being used. In this case, the plastic
tube in the Flowcell replaces the function of the Probe sleeve.
2.4. About the Lanyard
The lanyard supplied with the Micro 800 Meter may, at first, appear to be a little long. This
is intentional. In order to keep the Meter out of the way whilst your hands are full, the
lanyard has been made long enough to wear round your neck and over your shoulder so
the Meter sits on your hip.
The extra length also allows the meter to be held in a comfortable position in front of you
during normal use. In order to prevent you being dragged into the water in the event of the
Probe cable becoming snagged, the lanyard includes a quick-release clip.
