INSREF Digital Non CFC Low Temperature
Calibration Bath, Cat. No. IRI 014


Polished Stainless Steel tank of filling volume 10 -12 ltrs and overall size 300 mm x 200 mm z 200 mm (D)
Capacity of upto 8 probes of dia 19 mm & length 200mm
Stirrer for uniform temperature in tank 
Long - life stainless steel immersion heater to maintain temperature extra long cold zone 
All other wetted parts are also of stainless steel
Tank insulation is formed-in-place Polyurethane Foam (PUF)

Operating temperature rang as per table below 
Digital proportional, fully solid state temperature control 
Accuracy of temperature control better than 0.1oC at minimum temperature 
Digital temperature  display with  resolution (least count) of 0.1oC
Accuracy of temperature display  0.5% of full range 1 digit
High temperature safety cut-off for heater (over temperature protection)

Cooling is by air cooled, fully balanced, long life mechanical systems, with single or
double stages (as required ) using hermetically sealed compressors and 
environment friendly, non- CFC gases
For double stage systems, necessary safety cut-offs
are built - in to allow unattended operation
Built-in Voltage Stabilizer with high & low voltage cut-off is provided to protect 
compressors from erratic power supply

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 AVAILABLE
Smaller / larger tank sizes - Smaller frame sizes - Higher Maximum Temperatures
