Lowest
temperatures typically reach within 90 to 120 minutes, at an ambient
of 27oC to 30oC. The lowest reachable
temperature varies with ambient temperature, quality & nature of
tank media and level of equipment maintenance. An air-conditioned
environment is most suited, though not absolutely necessary.
While calculating space requirements based on the above data, please
take into account free air circulation space of at least 300 mm on
all sides of the equipment.
Suggested tank liquids are distilled water for operating
temperatures above 5oC and good quality methanol for
operating temperatures below 5oC.
The Digital Temperature Display is calibrated at our factory against
thermometers which have calibration certificates traceable to
national standards. Calibration Certificates from a Government of
India lab, traceable to national standards for individual equipment
can be given, at extra cost.
It is suggested that models with Cat. No. IRI 014 H & IRI 014 I
are used consistently only at temperatures lower than -20oC,
and only intermittently for higher temperatures.
OPTIONS
