Arsenometer HMAS100
Instruction Manual v2.0
The instrument also consists of:
Stirrer
– the stirrer will not operate all the time during the different stages
of a run. The stirrer is crucial to the operation of the instrument and
needs to be checked to ensure it is working properly. During a run, look
through the translucent beaker or lightly touch the bottom of the SAB to
determine that the stirrer is rotating when indicated on the handset. The
stirrer has been designed to minimise turbulence thus ensuring
increased repeatability.
Sample Analysis Beaker (SAB)
– the SAB has a fixed volume so
that when full and removed from the water course, excess
sample will empty out of the holes levelling off at a constant
volume.
Handset
– the handset is waterproof and robust. A periodic visual inspection
to ensure it is not damaged and that the screen is readable will suffice.
Buffers
– the buffers are powders, which should be stored in a
dark, cool, dry environment. If stored correctly, these have a
shelf life of 3 years. Refer to individual sachets for expiry dates.
