Other recorders with internal sensors only are available from $ 300 - $ 400. All have only a single Temp/RH input. They do not have remote sensor inputs or alarm contacts. Some of the lower-cost chart recorders do not have 120VAC power adapters available and none can output to a computer. The ThermaViewer comes complete with 2 temp/RH remote sensors, alarm contact, 120vac power adaptor, and can be output to a computer, making it a much better value than any of the above.
