Oakton<sup>®</sup> Hygrothermographs

Oakton® Hygrothermographs

To monitor and record relative humidity and temperature conditions. All models feature a human hair bundle humidity sensor (domed mini-drum model has dual bundles) and an aged bimetallic strip temperature sensor. Response time is 15 minutes for 45% of reading. Each unit is individually tested and includes a factory certificate stating that it meets or exceeds stated specifications. Each hygrothermograph also includes all the components necessary to get started including two felt-tipped pens (one blue and one red), one seven-day sheet of chart paper (one roll of one-month paper with long cycle model) and batteries. Hygrothermographs 354-27463, 354-27460 and 354-27466 are shown with optional axial fan for more uniform sample measurements in fluctuating environments.

Cat. No. 354-24895 Economical Mini-Drum Hygrothermograph:
Records temperature and humidity on seven-day rotation. It can be used in tight places such as under fume hoods or inside environmental chambers. Quartz-controlled drive mechanism rotates drum at a single speed.

354-27463 Two-Speed Hygrothermograph:
is a spring-wound model which records temperature and humidity on a one- or seven-day rotation. Made of lightweight, corrosion-resistant acrylic for indoor or sheltered outdoor use. Spring winding keeps chart running for eight days. Even when the motor begins to run down, a steady chart speed is maintained. Includes one 1-day gear and one 7-day gear.

354-27460 Battery-Operated, Three-Speed Hygrothermograph:
Select to record temperature and humidity for one, seven or 32 days with the flip of a switch. Lightweight, corrosion-resistant case for indoor or sheltered outdoor use. Quartz-controlled drive mechanism consistently rotates chart drum even when batteries are weak. A flashing LCD indicates the unit is operational.

354-27466 Long-Cycle Hygrothermograph:
Records temperature and humidity on a one- or three-month rotation. Quartz-controlled strip chart drive consistently rotates chart drum even when batteries are weak. This unit features a corrosion-resistant acrylic plastic case with tinted cover for easy viewing.
