Precise temperatures for precise calibration
29 Jul 2004
Calibration thermostats have a separate chamber adjustable for height in order to achieve an optimum temperature gradient and an optimum temperature stability
Temperature sensors, temperature measuring devices or thermometers are control mechanisms or measuring instruments that must conform to certain constancy demands.
These guidelines are usually laid down in the statute books in the form of national and international standards.
Before these control instruments can be used, they are calibrated or adjusted.
And this is where Lauda calibration thermostats come into their own.
In order to be able to obtain optimum values when performing the calibration or adjustment process, certain factors such as temperature gradient, temperature stability and immersion depth must be kept as constant as possible and be reproducible again and again.
In order to achieve an optimum temperature gradient and an optimum temperature stability as well as immersion depth for the control instruments, Lauda calibration thermostats have a separate chamber that is adjustable for height.
Lauda says it caters for the various demands made by users.
This is why there are different Lauda calibration thermostats that vary in bath size, immersion depth and temperature range.
Lauda Proline calibration thermostats are a new addition to the range.
This product line allows the user to put together the thermostat to precisely match requirements.
The types PJ 12 and PJ 12 C have a temperature range from 30 to 300C.
In conjunction with a Lauda add-on cooler they can be operated at temperatures down to 0C.
Although the special insulated variants PJL 12 and PJL 12 C are limited to a maximum 200C, they can boast temperatures of up to -40C in combination with a Lauda add-on cooler.
All devices have a particularly large bath depth.
They are suitable for the use of several thermometers at a time due to the diameter of the usable area of 120mm.
The cooling devices RE 212 J and RE 312 J offer a temperature control of +/-0.01 C within the attractively priced Ecoline range.
The thermostats work in a temperature range from -30 up to 200C, with up to 12 litres bath volume and an integrated automatic cooling system.
The Ultra range of calibration thermostats is suitable for the most demanding of requirements.
They are available in models from 20 up to 300C or with the through-flow cooler DLK 45 suitable for temperature ranges between -40/-35 and 200 C.
Fitted with the digital controller R 400 PL a separation is achieved between the thermostat bath and the control.
Rotoracks to take thermometers are also available as an accessory on request.
