Extech RHT30 logs air humidity and temperature in harsh sites, and it keeps going without fuss. Two built-in sensors feed precise data into a roomy memory that captures shifts day and night.
Fast Download, Zero Software Fuss
Extech RHT30 ends cable clutter because the full-size USB blade plugs straight into any computer, and reports open by themselves as clear PDF or spreadsheet files. You read trends in seconds and move on with the job.
Flexible Control in the Field
You choose the sample rate, alarm limits, delay times and even one of six languages, and Extech RHT30 stores the mix with password protection so settings stay safe. An LED that shines green, amber or red tells crews if limits break before costly spoilage begins.
Because Extech RHT30 holds forty-eight thousand readings, you can leave it for weeks while the tough housing resists knocks, dust and splash. When memory fills, one touch stops logging and the bookmark marks key events for faster review later.
