Manufacturer's Description
Braun Ear Thermometers work best with Braun LF40 Lens Filters. Take your temperature accurately and hygienically with these replacement lens filters for Braun thermometers. Designed to comfortably fit ThermoScan Ear Thermometers, this pack includes 40 lens filters, allowing you to protect your sensor from scratches and dirt for maximum hygiene between use. Each filter may only be used once, reducing the risk of contamination.

The ear is regarded as the most reliable place to get a consistent reading of the humans core body temperature. You should measure your child's temperature regularly to understand their normal reading, so you can recognise signs of fever early.

How do Braun Ear Thermometers Work?

1. Eardrum emits infrared radiation.
2. Infrared radiation passes through the lens filter.
3. Depending on the specifications (material, thickness, production process etc.) the lens filter lets pass a reduced amount of infrared radiation.
4. The sensor of the device receives a reduced amount of infrared radiation.
5. With a complex algorithm specially adjusted on the specifications of Braun lens filters the ThermoScan ear thermometer converts the infrared radiation into a temperature being shown on the display.
An infrared ear thermometer and the lens filter always work as a system. To get an accurate reading it is mandatory to align specifications of device and lens filter.

Hygienic
Cross contamination is virtually eliminated with use of LF40 disposable filters.

Box Contains

• 40 x disposable lens filters

Customer Reviews

Good product, necessary for hygenic use.
Good product, basically a 'condom' for the lens on the thermometer, which stops wax and possible infectious stuff from being transferred to different people, and keeps it hygenic for you too.
Good value, best price around is on here, and the packs last for ages, as you dont need a new one each time if it is only for you, just a wipe with a tissue!
Hope this helps, a definate buy!

necessity more than anything
These lens are indeed great for taking temperature... but at a price! Amazon price may be the cheaper, it still a lot if your baby is sick and you have to monitor the temperature every other hour, having to replace the filter every time.

For me, these filters do the job very well, but remember to pile up plenty. Otherwise you'll have to throw the thermometer the day they stop selling the filters!
I still use the old "traditional" thermometer from time to time, partly for this reason.
No problem with the filter, only wish they would come in packs of 200 for that price!

Good product slow delivery
This is a good product at a very good price. It took a bit of time to send it to me with little communication.
