Introduction Extech RH520A-220

Graphical datalogger for Humidity/Temperature measurements and Dew Point calculation

This paperless chart recorder provides a simultaneous digital and graphical display of relative humidity and temperature. The display also shows dew point, date and time, and Min/Max measurements. Stored readings can be recalled on the display or downloaded to a PC to obtain a permanent record. Provisions for wall mounting or the control panel swivels to act as a desk stand. The user can set audible and visual alarms with High and Low limits for humidity and temperature. ExChart software calculates Wet Bulb and Grains per Pound (GPP). Comes complete with a detachable sensor probe with 1-meter cable, RS-232 cable with the USB adapter, Windows-compatible software, 220 VAC adapter, and three AA batteries.
