Extech 42280A Temperature and Humidity Datalogger
The 42280A keeps watch on temperature and humidity and records up to 24,000 readings, each with a date and time. When it’s time to report, plug it into a PC and it produces a PDF with trend graphs, or export the data to Excel.
Reports with less work
Add up to eight time-stamped markers while it logs, such as when a door was opened or a dehumidifier was switched on, and they show up in the report.
Alarms and limits
Set high and low limits on the meter or from your PC. Audible and visible alarms tell you when conditions move outside them.
Mount it where it works
Put it on a wall, a desk or a tripod. The screen shows humidity, temperature, date, time and the max and min readings. Passwords protect the logged data.
In the box
USB cable, AC adaptor with an Australian plug, and four AA batteries.
