Cole-Parmer 2-Speed, Spring-Wound Hygrothermograph (each)
Use this hygrothermograph for indoor or sheltered outdoor use. The sturdy base, tinted cover, and carrying handle are constructed of lightweight, corrosion-resistant acrylic.
Hygrothermometer needs no external power or batteries; spring winding keeps the chart running for 8 days. Unit maintains a steady chart speed even when the motor begins to run down. Two easy-to-change gears are included; one for 1-day (26-hour) rotation and another for 7-day (172-hour) rotation.
Feature a human hair bundle humidity sensor and an aged bimetallic strip temperature sensor. Response time is 15 minutes for 45% of reading.
Exposure to RH levels above 90% can cause a decrease of about 7-10% RH in readings over the entire range due to temporary elongation of the hair bundle. When exposed to humidity levels below 80%, hair bundle will return to normal in about three weeks.
