美***OMEGA歐米茄MFR0122恒濕器/濕度調(diào)節(jié)器濕度控制

可調(diào)相對(duì)濕度范圍

開(kāi)關(guān)容量大

可安裝DIN導(dǎo)軌

MFR012設(shè)計(jì)用于控制外殼內(nèi)的相對(duì)空氣濕度。當(dāng)連接到外殼加熱器（去濕器）時(shí)，它將在設(shè)定的濕度水平打開(kāi)加熱器，以提高露點(diǎn)。這有助于防止冷凝和腐蝕引起的電子元件損壞和故障。MFR012還可用于控制冷卻風(fēng)扇、警示燈或其他設(shè)備。

Adjustable Relative Humidity Range

High Switching Capacity

DIN Rail Mountable

The MFR012 is designed to control the relative air humidity inside of enclosures. When connected to an enclosure heater, (de-humidifier), it will turn the heater on at the set humidity level in order to raise the dew point. This helps prevent damage and malfunction of electronic components caused by condensation and corrosion. The MFR012 can also be used to control cooling fans, warning lights or other devices.
