Calibration Services

Calibration of your equipment can be achieved in two ways:

By one our engineers to visit you and calibrate your equipment on site

By sending us your equipment in the post for calibration

We calibrate a wide range of calibration equipment from manufacturers including:

 Icespy, Comark, Hacow, Dumo, Isotech, Labfacility, Techne, Tinsley,etc.

The range of products that we calibrate includes those listed below but this is by no means exhaustive so please contact us with your requirements.

Electronic thermometers with sensors ie Kaye probes

Platinum resistance thermometers PRT & SPRTS

Metal Block bath calibrators and portable liquid baths

Thermocouples - base metal ie J,T,K,N,E,L,U

Thermocouples - noble metal ie R,S,B,G,U

Digital Temperature indicators

Electrical calibration of temperature indicators,
controllers and recorders for the following sensors:

Electrical calibration of Temperature Simulators for:

Metal Thermocouples

Resistance Sensors

AutoClaves

A thermometer without a traceable calibration route to recognised National Standards ITS-90 is fairly useless.
Yet we all buy mass produced thermometers which are supplied without a calibration and use them.
I assume we all hope that the manufacturer has been conscientious and has at least carried out calibration checks on batch samples and has claimed a level of accuracy to the batch,
This is why Thermal Systems offer FREE OF CHARGE a calibration cerficate with all new equipment that we supply.

The only way of being confident in a thermometer is to have it annualy calibrated, then we can be sure that the reading it gives is meaningful.
You would not rely on the time from your wrist watch being accurate unless you had checked it would you?
Yet we run industrial plants, and food safety check's with un calibrated thermometers!

Temperature is one of the most commonly measured physical quantities but its basis is not widely understood.
Unlike other quantities, such as mass and time, temperature is defined on a theoretical set of conditions whereas other units are based on real physically realisable defined conditions.
For instance the perfect kilogram is in Paris and time is based on atomic transitions in a caesium atom.
Temperature is based on the thermodynamics of perfect systems, such as ideal gases and this results in the thermodynamic temperature scale measured in Kelvins (K), which is unattainable.
What we do is the next best thing and use thermodynamic systems to achieve a working temperature scale as near to the theoretical one as we can get.
The current working temperature scale is the International Temperature Scale of 1990 (ITS-90) and is measured in degrees Celsius (°C) for temperatures above 0° C and K or °C are used below 0° C (1° C = 1K).
A Kelvin (K) is a degree of temperature, equal in size to a Celsius degree (C), on a scale that begins at absolute zero.

0° K (absolute zero) = -273.16°C

Because each Celsius degree equals one Kelvin degree, 0° C = 273.16° K.

Add 274.16° degrees to each side of the equation, then 1° C = 274.16° K.

When we calibrate our thermometers it's to the ITS-90 temperature scale .

ITS-90 are Internationally agreed temperature values in ° C assigned to repeatable physical phenomena that occur at a constant temperature by using fixed points, like the boiling point of water 100°C and freezing point of water -0.01°C but you are limited to a small selection of points over a temperature range this is why we take great care in establishing true traceability to recognised National Standards.
