Techne Temperature Calibration Equipment
Precision FB08 Series Fluidised
Baths
Description and operation The FB08 is a rectangular bench standing unit. The controls for temperature
and fluidizing air flow are mounted on a recessed panel on the front of the
unit, together with on-off switches for the power supply and the dust extractor
and indicators for various functions. Insulated and vented the outer case is
safe to touch even at the maximum operating temperature. The inner container is
filled from the top with alumina. When fluidised, this medium is heated by four
immersion heaters close to the container wall with the control thermocouple
between the heaters. The internal components are protected by an air cutout
switch that disables heat in the event the fluidizing air is
lost. In operation, set the fluidizing air by means of a combined control valve and flow meter. (Note: air adjustment is automatic with the FB08C) Fluidizing air requirements are inverse of the bath temperature. i.e- lower bath temperatures require more air for proper fluidization. The bath temperature is set by means of a front panel mounted PID controller. Sensors for calibration should be suspended as close as possible to the center of the bath. When calibrating sensors the probe holder is recommended as it is custom built with the dimensions of the sensors you will be calibrating. Dead-Bed Operation
Models to choose from: The FB08 is offered in three different models. The standard FB08 operates from +50 to 700°C, in addition to the standard unit the FB08C offers automatic fluidizing air control and is capable of remote PC operation. When connected to your liquid nitrogen supply the FB08LT operates between -100 and +200°C. The single probe plate and ring are included with the baths. You will also receive one 35lb. charge of alumina to get started. Specifications

LCB-7 |
LCB-7 Calibration Bath Compact, accurate and reliable liquid baths for calibration.
|
| Controllers incorporate the safety features
of overtemperature cut-out and low liquid level device. LCB-7 baths have a
thermometer hole to take a reference thermometer, drain tap, lid, carrying
handles and insulation on sides and base. A built in cooling coil is
included. The system offers a display accuracy of ±1.0°C, but if you
require higher accuracy take a look at one of the thermometer
systems we offer. We recommend the use of our bath liquids to get the best performance at a wider range of operating temperatures. |

LCB-12 |
LCB-12 Calibration Bath Compact, accurate and reliable liquid baths for calibration.
|
The LCB-12 bath has a thermometer hole to take a reference
thermometer, drain tap, lid, carrying handles and insulation on sides and base.
A built in cooling coil is included. The 12 inch immersion depth of the LCB-12
makes it an excellent choice for use in the calibration of liquid in glass
thermometers, RTD's, thermocouples and fluid filled bulbs. Controllers
incorporate the safety features of an over-temperature cut-out and low liquid
level device. The system offers a display accuracy of ±1.0°C, but if you require
higher accuracy take a look at one of the thermometer
systems we offer.
We recommend the use of

Portable
Thermoregulators | |
| Inventors of the "Clip On" thermoregulator in 1948, Techne® now offers five "Clip On" units. These Thermoregulators will convert your existing liquid bath or container into a precision temperature controlled bath with exceptional thermal performance. They offer a full range of options such as analog or digital set/readout, high pump output and RS232 interface. | |
|
|
The
TE10A clip on thermoregulator offers a temperature range
capability of -20°C to + 95°C, covering most
routine laboratory applications. A circulating pump with external
circulation connections is standard, as is adjustable over-temperature
cutout. |
|
|
The TE10D
Tempunit offers a temperature range capability of between
-40°C to +120°C. There is a digital temperature
selector, circulating pump with external circulation connections,
adjustable over-temperature cut-out and low liquid level cut-out. The
TU20D has a temperature range capability of -40°C to
+200°C and incorporates the additional feature of an RS232
port. The top of the range TU20C has additional features fitted as
standard including an audible alarm, a high capacity dual pressure pump,
cooling coil and also includes an RS232 port. The temperature range
capability is -40°C to +250°C.The TU20HT is designed for internally circulated baths, thus it is not capable of external pumping for re-circulation, but does include the cooling coil, Thermsoft software and has an operating temperature range capability of -40 to +250 °C. For applications that
require sub-ambient operation, see our refrigeration
units for use in combination with the unheated baths or one of the
refrigerated
baths for an integrated system.Download the full version of ThermSoft software. It allows you to create ramp and dwell programs and remotely control the TU20D, TU20C and TU20HT from your PC . Thermsoft is included with the TU20C and TU20HT and is a free download for the TU20D. |
