Refrigerated Temperature Calibration Baths
Complete refrigerated circulating system for open or closed applications for temperature ranges from -35°C to 100°C. Each bath is supplied with a lid & bridging plate.
There are three bath capacities: 7 litre (RB-5A), 12 litre (RB-12A) & 22 litre (RB-22A).
Temperature control is via one of the four thermo regulators & together they offer a choice of 12 different bath combinations.
• Circulating bath with built in refrigeration
• Temperature range from -35°C to 100°C
• Three capacities of bath; 7, 12 or 22 litre
• The combination of 3 circulating baths &
4 thermo regulators to choose from.

Dip Coolers (cold finger)
The cooling head of the Techne® Dip Cooler fits neatly and unobtrusively into the corner of a liquid bath & can be secured with a specially designed mounting bracket (supplied). If cooling can be achieved by using cold tap water, a dip cooler is recommended as it conserves water & is easier & more convenient to use.
Techne® Dip Coolers are designed for use when temperatures down to –35°C are required.
• Two models
• Compact refrigeration units for achieving
temperatures down to –35°C*
• Cooling head of the Dip Cooler fits neatly into
the corner of a Techne liquid bath( RU series of
dip coolers)
• Designed for use with Techne liquid baths

Flow Coolers
The Techne® Flow Coolers work in conjunction with a Techne® thermo regulator. The bath liquid flows through the unit which continually extracts heat from the bath fluid by means of the heat exchanger which is built into the unit.
Techne® Flow coolers are designed for use when temperatures down to –35°C are required.
• Two models
• Compact refrigeration units for achieving
temperatures down to–35°C*
• Designed for use with Techne liquid baths

RCB-80 Ultra Low Temperature Bath
The RCB-80 is a mechanically-refrigerated bench top circulating low temperature calibrating bath that provides precise temperature control for a wide variety of applications & eliminates the cost & potential hazards associated with using dry ice or liquid nitrogen.
It offers a 4 litre bath capacity with an ultimate low temperature of -80°C. A built in magnetic stirrer, with variable speed control, provides excellent temperature uniformity & stability. A custom-fitted phenolic cover is standard with every unit when a probe holder is not ordered.
For sensor calibrations, we suggest ordering the probe holder for placement of probes under test.

Portable Drywell Temperature Calibrating Block Baths are found here
Important points to consideration when selecting a temperature calibration bath for calibration by comparison:
A temperature probe is calibrated in a block by comparison with a known reference thermometer which should have a system accuracy of at least four times that of the thermometer being calibrated. For accurate calibration,
the two thermometers must be in thermal equilibrium which requires that they are as close as possible over their full length
and ideally of similar thermal mass, and response time.
A separate reference thermometer, with no limitations of being built-in, is a much better option as it is placed close to the thermometer or sensor being calibrated & can be easily calibrated & re-calibrated over a wide temperature range to traceable national standards.
So, instead of having to send the calibration bath away for annual re-calibration, you need only to send your external reference thermometer away for re-calibration, saving freight costs and down time.
