What is an IP Rating?

Many of the products we supply have an IP Rating. This is to help customers who work in a range of different environments make an informed decision when choosing a product. If there is no IP Rating stated in there listing that instrument does not have one, if you require some help choosing the right instrument please speak with on on our Live Chat. Below explains how an IP Rating is achieved. 

The digits (characteristic numerals) indicate conformity with the conditions summarized in the tables below. For example, a thermometer rated IP66 is dust tight and powerful water jets. 

First Digit: Solids

The first digit indicates the level of protection that the enclosure provides against access to hazardous parts (e.g., electrical conductors, moving parts) and the ingress of solid foreign objects.

Level Object size protected against Effective against
0 Not protected No protection against contact and ingress of objects
1 >50mm Any large surface of the body, such as the back of the hand, but no protection against deliberate contact with a body part.
2 >12.5mm Fingers or similar objects.
3 >2.5mm Tools, thick wires, etc.
4 >1mm Most wires, screws, etc.
5 Dust Protected Ingress of dust is not entirely prevented, but it must not enter in sufficient quantity to interfere with the satisfactory operation of the equipment; complete protection against contact.
6 Dust Tight No ingress of dust; complete protection against contact.



Second Digit: Liquids

Protection of the equipment inside the enclosure against harmful ingress of water.

Level Object size protected against Effective against
0 Not protected
1 Dripping water Dripping water (vertically falling drops) shall have no harmfull effect.
2 Dripping water when tilted up to 15° Vertically dripping water shall have no harmful effect when the enclosure is tilted at an angle up to 15° from its normal position.
3 Spraying water Water falling as a spray at any angle up to 60° from the vertical shall have no harmful effect.
4 Splashing water Water splashing against the enclosure from any direction shall have no harmful effect.
5 Water jets Water projected by a nozzle (6.3mm) against enclosure from any direction shall have no harmful effects.
6 Powerful water jets Water projected in powerful jets (12.5mm nozzle) against the enclosure from any direction shall have no harmful effects.
7 Immersion up to 1m Ingress of water in harmful quantity shall not be possible when the enclosure is immersed in water under defined conditions of pressure and time (up to 1 m of submersion).
8 Immersion beyond 1m The equipment is suitable for continuous immersion in water under conditions which shall be specified by the manufacturer. Normally, this will mean that the equipment is hermetically sealed. However, with certain types of equipment, it can mean that water can enter but only in such a manner that it produces no harmful effects.

Why wont my thermometer turn on?

If you have just received your thermometer, we always suggest that you check the battery compartment . Some thermometers are supplied with their batteries separately, so will need inserting. 

If you have had the thermometer for a while, check the battery compartment and change the batteries and check the metal clips that hold the batteries in place are undamaged. 

If you are still experiencing problems, please speak with our team on our Live Chat or email us on

Can I use a Infrared Thermometer when cooking food?

Infrared Thermometers only measure surface temperatures. So they are not the right tool to check if food is cooked.

We suggest using the traditional probe for this as this will provide you a core temperature.
