Extech 445815 Humidity Meter with Alarm and Remote Probe

- Calibrated using Boveda- Well-built and BIG digital display...readings can be seen clearly from far away!- ACCURATE and FAST response time, almost INSTANT actually!- TEMPERATURE & RH% readings are very useful in any environment, but it does DEW Point readings as well...which is a BIG plus!- Probe can be detached to take readings behind walls if necessary, which is super convenient & handy- MIN & MAX can be reset, but can also be used to trigger a beeping ALARM which is more useful than it seems- This product only PROVES that EXTECH's already excellent reputation in this industry is WELL-DESERVED and 100% JUSTIFIED- Cheap analog meters do not guarantee fast, accurate & reliable readings...so stop wasting your time and invest in a good HIGH-QUALITY tool like THIS one and say bye bye to those analog meters for good!

Il prodotto mi è arrivato nei tempi previsti, amazon è impeccabile.Lo ho testato con termo igrometro professionale (250 € la sola sonda con compensazione barometrica) e ho visto che è arrivato tarato alla perfezione, non è stato necessario intervenire.Il funzionamento è molto semplice.Per questo prezzo è davvero un ottimo prodotto, potete settare allarme della U.R. al valore desiderato, unico allarme è sulla umidità !Ottimo davvero.Utile per capire quando è ora di aprire le finestre.

I bought this after much research and I'm sure I have made the right choice.I suffer badly with COPD and I need a more accurate reading of the air quality in my home so I can set my other equipment to fine tune the air for better breathing ....Firstly...It is very accurate and you also have the ability to calibrate it with the appropriate Kit but it is £30,but remember...DO NOT mess with these adjustment screws unless.A) you know what your doing and B) you own the calibration kit,,They are not there to tamper with otherwise and even when using the screws ,only very small adjustments have to be made each time allowing 30 mins between each adjustment if temp and Dew point is essential then look no further..It also comes with an 18" probe which sits on the side in it's own little holder...this is great for those hard to get to places that need to check if damp has set in. It's real easy to set up and it's quick to respond to the atmosphere around it which is handy as you don't always want to leave it hours on end for results...It's also very well made with a small kick stand at the rear to place on any flat surface..You also have the ability to set a high and low humidity (maybe more for those monitoring technical equipment) and also a reset button to see what changes have occured during the day. I will point out that it IS Green with a silver accent and not black as the main photo shows,but it looks quite smart none the less...£40 gets you a great accurate Temp gauge and Dew point monitor and it does a fantastic job.Highly recommended

Besitze seit Jahren ein Extech 445815,Nachdem ich in der Amazon-Suchmaschine nach Feuchtmessgeräten suchte, fand ich ein optisch ähnliches Gerät mit mobiler Sonde.Hiervon bestellte ich zwei Geräte und ward von der Genauigkeit schwer enttäuscht; wer das Lüften des Kellers und des Hauses ernst nimmt, kann mit TP-Differenzen von 3 Grad nicht zufrieden sein.Dann suchte ich gezielt nach dem Extech 445815, von welchem ich dann drei Geräte bestellte.Die drei Geräte haben eine gute vergleichende Genauigkeit und entsprechen auch dem langjährig benutzten Gerät.Ein Gerät musste in der Temperatur etwas nachjustiert werden - und dann stimmte auch dieses sehr gut.Und nun zu den Vorteilen dieses Gerätes:Das Gerät hat eine relativ sehr gute Grundgenauigkeit - die Grundmesswerte relative Feuchte und Temperatur lassen sich über zwei Potentiometer in Grenzen nachjustieren.Die externe Sonde sorgt für eine relativ schnelle Messwerterfassung (im Gegensatz zu Geräten mit integrierten Fühlern im Inneren des Gehäuses) - und dies ist sehr wichtig zur schnellen Entscheidung über das Lüften insb. des Kellers besonders in den Sommermonaten.Warum gleich mehrere Geräte - diese habe ich im Hause verteilt und eines dient der schnellen Feuchtigkeitserfassung der Außenluft (das Gerät sollte aber nicht dem Regen ausgesetzt sein - leidvolle Erfahrung vor einigen Jahren).Bei mir gibt es keinen muffelnden Keller - dazu muss aber auch die Einsicht der Frau beitragen, dass man bei schwülwarmen Wetter den Keller besser nicht wischt - ein oft mühsamer Überzeugungsprozess.

Uno dei pochi che oltre a temperatura e % di umidità, indica il “Punto di Rugiada” (DEW). Ne ho acquistati due; uno da tenere in casa e uno per la misurazione dell’esterno. Quando il DEW in casa è superiore rispetto all’esterno, so che posso arieggiare senza correre il rischio di far entrare in casa aria più umida.
