The REED R6030 is a compact data logger that records temperature and relative humidity readings automatically over time, storing up to 32,000 readings with a user-selectable sampling interval from 1 second to 24 hours. It measures temperature from -40 to 158F (-40 to 70C) and humidity from 0-100% RH, and includes a built-in LCD showing current and min/max readings plus a real-time clock for date/time stamping. Data is configured and downloaded via USB, and the unit ships with a wall-mount bracket, security lock, and battery for long-term monitoring installations.
