Cole-Parmer Economical Minidrum Hygrothermograph (each)
This hygrothermograph is so compact it will fit almost anywhere; measures just 6.00''W x 7.38''H x 3.88''D.
Hygrothermograph employs a quartz-controlled drive mechanism for constant speed; operates for 6 months on one AA battery (included). Chart rotation period is 7 days. Acrylic cover latches securely to protect paper and pens and is easily removable.
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.
