Digital Hygrothermograph with Temperature and Humidity Monitoring

Description

The Seedburo Hygrothermograph can be used for indoor or (sheltered) outdoor use. The unit provides a permanent record of temperature and relative humidity changes over a 1-day or 7-day period (and 32-day for No. 3725Q) and measures in °F or °C by changing chart paper. A removable clear plastic cover with handle allows for chart and component access.
Available in two models, the Model 3725 is spring wound and includes two easy-to-change gears for 1-day or 7-day rotation. The Model 3725Q is powered by two “C” batteries (included) and features a quartz-controlled drive mechanism. With the 3725Q the user can select 1-, 7- or 32-day operation with the flip of a switch. Each unit includes two felt tipped pens (blue and red). An optional axial fan is also available for both units to produce more uniform measurements in environments with varying conditions.
