The HM40 ThermoHygrometer is the advanced version of the popular Phoenix HMI-41, which has a well-earned reputation for its accuracy and dependability. Manufactured by the Vaisala Company in Helsinki, Finland, the Phoenix HM40 meter will provide years of trouble-free service.
The HM40 ThermoHygrometer offers the following readings:
For spot-checking and analyzing drying conditions, the HM40 is a must. It incorporates Vaisala's HUMICAP® 180R Sensor, which is accurate, durable, and resistant to dust and most chemical contaminants. The HM40 provides superior and precise readings in tough environments.
The HM40 includes a user-friendly, large graphic display and easy-to-use push buttons along with an intuitive interface. Users can choose from 10 languages, which is especially handy for overcoming any language barriers and ensuring results are accurate no matter which language the user is most fluent in.
Other settings can also be modified by the restorer to best suit his or her individual needs. In addition to relative humidity and temperature, the HM40 provides five calculated humidity parameters, available in both metric and nonmetric units, including dew point, wet bulb temperature, and grains per pound.
The HM40 Humidity Meter is available in either the standard version (PH-4034285-EA) or remote probe version (PH-4034345-EA). The graph clearly indicates when the readings have stabilized. The meter is powered by 2 AA-sized batteries. An external NiMH battery recharger with USB connection and rechargeable NiMH batteries are offered as an option. Each HM40 comes also with a handy belt clip and a case.
