仪器简介：
The hygrotest was specially developed for humidity measurement in air conditioning technology and process engineering. Its popular long-term stability make it ideal for these demanding measurements (see inter-laboratory test). The result of hygrotest's years of development and market experience is, for example, a measurement range of 0 to 100%RH and a standardized measurement accuracy of +/-2 %RH (optionally +/-1 %RH for the hygrotest 650. With its innovative heated technology, the hygrotest 650 HP is perfectly suited to high humidity applications, and guarantees fast sensor reaction times and a long life under extreme humidity conditions (close to the 100% limit). Two freely scalable analog outputs and a digital output RS232 are available for the output of relative humidity, temperature, absolute humidity, wet bulb temperature or degree of humidity - optionally with a digital output RS485 in combination with the displays H3, H4 and H5. The hygrotest also excels by its compact and robust design, as seen for example, in the metal housing of the hygrotest 650/650 HP.
