We are the Thermometer Specialist

We stock a very wide range of thermometers for almost every application. Your looking for a thermometer and we want to help you find the correct one for your needs. Call the specialist whether you need a basic room thermometer or a HACCP complaint unit for taking regular temperature readings.

Temperature monitoring is used in a wide range of services and applications but the fundamental basic remains the same. They are designed to measure the change in difference of temperature with a defined scale. The most common of these are Kelvin K, Celsius °C and Fahrenheit °F of which most instruments commonly used will normally refer to Celsius °C.

For the most part the use of modern thermometer equipment is concerned with what you actually want to measure and how accurate you need to be. For example measuring extremely hot substances in the 1000’s of degrees we not be to concerned about 10 degree increments. However when testing food in the catering industry you may be required to have equipment that is accurate to within half a degree.

Today thermometers come in a wide variety of styles and designs, both analogue and digital version are available and it’s important to understand that the accuracy of a thermometer is not the same as the resolution it will work to. Resolution is concerned with the reading you receive for example 10.5 °C means the unit can measure down to one tenth of a degree whilst no decimal point means the thermometer would either read 10°C or ll°C.

However as stated this is not the same as accuracy, it may be that the thermometer is not 100% accurate so when the reading states 10.5°C it could be 12.5°C. In order to to check the accuracy of any thermometer it needs to be calibrated. Put simply, tested against a reference point such as a thermometer that is known to be accurate. In reality equipment these days is normally accurate straight out the box and will fine for most peoples requirements. If you need to be very accurate with your measurements please read this article calibration

A development which we are still asked about that effected thermometer equipment was the banning of the use of mercury in analogue thermometers this came into force on the 3 April 2009 effectively banning the sale to the general public. Please be aware that modern thermometers use an alcohol based liquid and that the mercury versions had to be withdrawn from shops in 2009. This does not effect equipment that was purchased prior to the 2009 date.

In most instances it’ snow possible to get digital thermometers for most applications, these tend to be quick in response, more robust and able to store from basic to huge amounts of data. Ideal if you take regular temperatures to record in a book or require an automated system that can store information over hours , weeks, or even months, Digital Thermometers and Data Loggers
