TFA 30.5010 Klima Guard Digital Thermo-Hygrometer

I really like this device. It can display both the temperature and the relative humidity at the same time. We don't use any of the more sophisticated modes in my family. This one has been working for a couple of years, we still like it. The memory for minimum and maximum temperatures is useful for checking how cold the kids' bedroom gets at night.

The product is more expensive than a number of similar products, but hopefully overtime it will prove its worth and value. Recommended on Heritage House website. Appears accurate and sensitive to changes in humidity. Of course, knowing your room temperature, humidity and dew points is only useful if you take action such as using extractor fans and opening windows to reduce condensation and humidity. Armed with this device and some research I now understand more about the importance of ventilation, and how to manage it.

appears very sensitive. set it quick and get away from it or it picks up your breathing moisture and mucks up max settings .good bit of kit.

This is a very nice, well-made Hygrometer and I've tried a few. Although I have always found it reads slightly higher than many of my others, it’s not such a problem in that it works best as a tool to show "change" or "variation". For those homeowners suffering damp a hygrometer is much more effective than a damp meter. If you experience high humidity (70% relative and above) then you have a problem with moisture and you are risking mould growth and damage to the fabric of your property. Find the source of the water, fix the problem that's causing the water ingress (and don’t be fooled into thinking you need chemical injection and waterproof plaster), and in-theory you should notice the humidity drop. Be warned, this process can take many money months or in my case up to 1 year. The process can be speeded up or at least controlled by the use of a dehumidifier, and Trotec do a fantastic range.TROTEC TTK 70 E Portable Air Dehumidifier, Dehumidifying max. 20 L/Day

Hygrometer & temperature unit works as expected. Only had it about a week so can,t comment about reliability but seems to work quite well, responding to the recent drop in temperature and showing the variations in humidity when we open the windows. Well made and the display is clear and quite large.

Was recommended this product. Does exactly whst it says it will. Dew point useful for room eith condensation, helped us understand the issue.

Arrived with damage to screen that appeared at first to be a cosmetic issue, but was actually damage to plastic covering which I presumed would potentially affect its operation in a humid environment, so it went straight back.

Bought this on recommendation from Heritage House website, and have been so impressed with the results. We had a significant problem battling damp in our house and because of Heritage House were able to conclude it was definitely condensation damp. We had been using a dehumidifier on and off, but were never sure how effective it was etc. Using this tool immediately told us what the humidity was in the house, and allowed us to open windows wide for 15 mins and were stunned at how effective that was in reducing the humidity in the house - it dropped 10% and we were then in the 40-50% humidity range which put the dewpoint safely within the temperature of the outdoors - we still use the dehumidifier when it's more humid outside, but now we know how long we need to have it on, etc and when we can simply open the windows. Having the dewpoint was especially helpful as it allowed us to figure out when we were at risk of getting condensation in the corners of the room etc. Ie. sometimes it was more humid in the house, but because it was so warm, the dew point was high enough that it didn't matter etc. Very pleased, and would recommend to anyone battling damp.
