ExtechSD700 Pressure, Humidity and Temperature Data Logger

Just what I needed

Wird verwendet, weil Mieter über oberflächliche Feuchtigkeit klagten. Der Logger kann im 1/2 Minuten-Takt Temperatur und Luftfeuchte messen; der Speicher reicht bislang für einige Wochen aus. Die Daten sind passwortgeschützt und können nur mit korrektem Passwort ausgelesen werden. Anhand der Daten kann das Lüftungsverhalten dokumentiert werden. Gut für eine allfällige Beweissicherung.

These are the humidity meters that we use for work. We don't use the measured dew point, instead we do our own calculations to determine it (I find that the measured dew point is off).This meter is very easy to use. Just make sure that you aren't holding the meter too close to your face (otherwise your breath will skew the results).

Worked consistently for 3 months then stopped all together, now doesn't turn on. Checked return and support coverage and that ended at 3 months to the date.Not worth the price, buy local

I just received the above product today. I have gone through the instructions on how to change from F to C which did work however it is already reading E2 error and needs to be recalibrated? According to the instructions this requires a salt reference bottle? Is this something that I now have to purchase? If so, we will likely return the unit. Please advise, thank you.
