Operation; Maintenance - Hach HIAC MicroCount-05 Liquid Sensor Manuel D'utilisation

Operation

W A R N I N G
Personal injury hazard. Never remove covers from the instrument. This is a laser-
based instrument and the user risks injury if exposed to the laser.
W A R N I N G
Fire hazard. The user is responsible to make sure that sufficient
precautions are taken when the equipment is used with methods that
use flammable liquids. Make sure to obey correct user precautions and
safety protocols. This includes, but is not limited to, spill and leak
controls, proper ventilation, no unattended use, and that the instrument
is never left unattended while power is applied.
W A R N I N G
Chemical exposure hazard. Obey laboratory safety procedures and wear all of
the personal protective equipment appropriate to the chemicals that are handled.
Refer to the current material safety data sheets (MSDS) for safety protocols.
N O T I C E
Make sure to flush the cell and sample lines completely with clean, particle-free
water immediately before use. Make sure that there are no leaks in the sampling
system to obtain accurate samples. Make sure that the sample is compatible with
water before use.
N O T I C E
Cover removal will void the warranty.
The sensor will be operated automatically with the connected particle
counter and the sampler systems. To optimize the sensor performance:
• Make sure to flush the tubing and the microcell with clean miscible
liquids between different sample analyses.
• Powder sample: Make sure to select an appropriate liquid to prepare a
powder suspension for the analyses. For a stable dispersion use a
surfactant. To remove air bubbles in the sample, the manufacturer
recommends that an Ultrasonic bath cleaner is used to degas the
sample (Replacement parts and accessories
• Keep the sample at ambient temperature. Cold liquids can cause
water condensation on the microcell window.
• Make sure that all samples are compatible with the components used

Maintenance

Clean the sensor and the microcell
Sensor body: Examine the sensor periodically for debris and deposits.
Clean the sensor when there is a build-up of deposits. Use a clean,
damp, lint-free soft cloth or a vacuum cleaner to remove loose debris
from the sensor body.
