Observator OMC-406 Temperature and Humidity Sensor
The air temperature and hum idity probe OM C-406 provides ac curate and prec ise m easurements of humidity and temperature. A dvancements i n s ensor and i ntegrated c ircuit t echnology has m ade i tpossible to achieve outstanding performance from a hand-hel d probe. Through the use of the probe and by proper application of basic procedures when obtaining humidity measurements the date will be reliable and dependable
Описание
The humidity s ensor used int he OM C-406 is as olid s tate dev ice which c hanges i ts el ectrical characteristics at extremely small changes in hum idity. T hese changes are det ected, linearized and amplfied as an anal og-output by uni que el ectronic Circuitry s pecifcally des igned f or maximum
performance. T he temperature sensing system also uses integrated circuit technology in combination with an accurate temperature element (PT-100) to produce high quality data.
