HI 8564
portable thermo-hygrometer with probe for measurements of RH and temperature

HI 8564 is a thermo-hygrometer portable, able to perform fast measurements of relative humidity and temperature.
The humidity probe is constructed of sturdy ABS plastic and is equipped with capacitive sensor and signal amplifier. The perforated cap on the end of the probe allows for good air circulation and at the same time protects the sensor. The standard version of this probe is supplied with 2 meters of cable, but it is also available with 5 meter cable.
hygrometer This is particularly suitable for measurements in closed environments, and is therefore recommended for use in libraries, archives, museums, typography and computer rooms.
HI 8564 is simple to use, all measurements are displayed on the liquid crystal display, which also shows the graphic symbols that indicate the operating mode of the instrument.
