Vaisala's HM44 kit meets the new ASTM standard and is the ideal solution for easy, reliable and accurate measurement of humidity in concrete. During construction, it is critical that concrete or other materials be dried precisely. Too short or too long a drying time can lead to problems costing both time and money. Avoid problems with Vaisala's HM44. For information, visit www.vaisala.com or call (888)VAISALA.
