Low maintenance, quartz-crystal hygrometer
Blygold treatments are bacteria and fungi resistant
MICHELL INSTRUMENTS HAS announced the launch of its recently enhanced QMA401 Low Maintenance Trace Moisture Analyser.
Maintaining this new generation quartz-crys- tal oscillator based analyser is simple, infre- quent and inexpensive. No service at all is re- quired for at least 2 years, at which point the desiccant dryer could need replacement – a pro- cess that can be carried out by the user in less
than 10 minutes. It’s straightforward to replace the internal moisture generator in the field with a freshly calibrated NPL or NIST traceable refer- ence unit from the factory, which will last for a full 3 years of operation.
The newly designed quartz crystal technolo- gy-based hygrometer features an improved touch-screen interface. The menu system is in- tuitive for easy operation following the struc-
ture known from Michell’s premium range of chilled mirror hygrometers. Operators, and service engineers, will be able to switch easily between the S8000 chilled mirror range and the QMA401. The case of the QMA401 has also been redesigned with a mod- ern, easy-clean surface, which is sim- ilar in look and feel to the S8000 pre- cision hygrometers.
Using the new generation of quartz crystal microbalance (QCM) sensor, the QMA401 precision hygrometer pro- vides consistently accurate measure- ments of trace moisture. This is achieved through an automatic self- calibration system which adjusts the analyser against an internal moisture generator (traceable to NPL and NIST).

Special coating
BLYGOLD PROVIDES CORROSION protec- tive coating for cooling coils and evaporators.
The coating shields vulnerable metals from aggressive environments.
The aluminium content in the coating provides the necessary heat conductivity for the coated exchangers. Special additives en- sure the applied coating film is bacteria and fungi resistant.
After treating evaporators or cooling coils these articles should be considered "treated arti- cles" and labelled as such.
The efficiency of the coating to resist bacteria and fungal growth has been tested and is avail- able upon request.

Explosion proof fans and chillers
A HOT ENVIRONMENT is made even hot- ter when working with a large amount of heavy machinery.
The combination of heat from the sun, plus that radiating off the machinery, can be haz- ardous on the health of employees.
Without an active cooling system in place, this combination of heat can cause extreme, irreversible dam- age to equipment, as well as, low pro- ductivity from
staff. Larson
Electronics
has a line of
e x p l o s i o n
proof coolers
and fans to
combat heat,
and save on en-
ergy and mainte-
nance costs.
Its line of classified fans provides cooling in hazardous work environments by stirring up stagnant air in low activity areas and then circulating fresh air around the work space. This movement helps to remove unwanted odours, smoke and dangerous fumes, as well
ing of heavy-duty machines and staff.
For hazardous areas with smaller access ways, Larson has a line of evaporative cool- ers and chillers. These explosion proof chill- ers combine a non-sparking aluminum fan with dry mist technology to cool hazardous work areas that do not have access to tradi-
tional air conditioning.
For workers in hazardous loca-
tions, these industrial fans and chillers help to not only keep them coolbuteliminatethehazardsthat come from breathing concentrated amounts of combustible gases. This combined with versatile voltage op- tions and extreme portability makes these perfect for any hazardous workenvironmentinseriousneedof
