ThermoPro TP55 Digital Room Thermometer Temperature and Humidity Monitor with All Time or 24hrs Max and Min Records for Temperature and Humidity Baby Room Thermometer with Large Backlight Touchscreen

Product Information

However, continuing with the theme of ‘simplicity’, there are only two buttons in total; the other allows you to alternate between Fahrenheit and Celsius depending on your preference. It will measure within the ranges of -10 to +50° in either unit. Some max/min thermometers will automatically reset after 24 hours, whilst others will need to be manually reset when required. I recommend a digital thermometer over a traditional analogue model . The displays are clearer and easier to read and interpret. You may wish to look for a thermometer that doubles up as a hygrometer (measuring humidity as well as temperature). These give a broader overview of growing conditions. A healthy humidity level in the UK is about 50-55% relative humidity (RH). Several of the hygrometers reviewed here show a smiley face when the humidity is at this level.

Too much humidity can cause damage to furniture, encourage mould to grow and lead to health problems. Too little humidity can be a problem too, as dry air can lead to dry skin and chapped lips. The TFA 30.5026.01 is a small digital thermometer and hygrometer which can be mounted on the wall or positioned on a table. All of the hygrometers we mentioned above are really accurate, but some that are available are not accurate at all. For taking basic temperature readings, look for a wireless digital thermometer that shows min/max temperature data as well as the current temperature. Thermometers that show maximum and minimum temperature over a certain period are really useful, as these allow you to see how much temperature variation your plants are experiencing. You can then plan ahead to keep your greenhouse’s temperature more consistent.

The best place to put a hygrometer in your home is in a common living area. It shouldn’t be near any windows or rooms that create excess humidity (like the bathroom or kitchen, for example). So, a living room or hallway are good places.

ThermoPro TP-55 Digital Indoor Temperature Humidity Monitor

The numbers for both the temperature and humidity are sufficiently large and easy to read, and the screen clearly displays other information as well. At a glance, directionally arrows indicate whether the temperature/humidity is dropping or rising, and the unit automatically interprets whether the humidity percentage is considered within ‘dry’, ‘comfortable’ or ‘wet’ levels.

Hygrometer FAQs

Accurate at low temperatures but some customers have found the temperature accuracy decreases as the weather gets warmer

The LCD screen is clear, so you can read it from a few metres away. One nice feature is that it a smiley face icon appears when the humidity is at a healthy level. According to the manufacturers, it’s accurate to ±1°C, and reports from customers seem to support this claim. Whilst not precise enough for professional use, it should give a good overall impression of the temperature and humidity inside the greenhouse.

What Is The UK’s Best Greenhouse Thermometer?

This device can measure temperatures from -50 to +70 °C, with both Celsius and Fahrenheit modes. It can also measure humidity from 10 to 99% RH. Some thermometers don’t mention any form of weatherproofing, in which case you should presume that they haven’t got any. For a greenhouse thermometer to be long lasting and effective, it should ideally at least describe itself as ‘water resistant’. Some analogue hygrometers are pretty difficult to read. If you need reading glasses, you’ll need to find them each time you want to monitor the humidity in your home. This can get a bit frustrating.

Most analogue hygrometers can be adjusted with a knob. Most digital hygrometers can also be adjusted and should come with instructions on how to calibrate them. If you can’t calibrate your hygrometer, you can take note of the difference and remember it for future reference. Where is the best place to put a hygrometer?In terms of accuracy, it seems to generally perform well as both a temperature and humidity gauge for non-professional use. It measures temperature in increments of one decimal place and the manufacturers state that it is accurate to ±1°C. Write: DIY Garden (Harris Creative Ltd), Lytchett House, 13 Freeland Park, Wareham Road, Poole, Dorset, BH16 6FA Data on screen is clearly laid out and easy to interpret, including arrows to indicate if temp/humidity is rising or falling The best hygrometer for you depends on your particular needs. If you are after a hygrometer for a specific task, like putting in a musical instrument case, for example, you will need one that is small enough to fit inside without damaging the instrument.
