China Electronic Hygrostat Adjustable Pre-Set Relative Humidity Temperature-Compensated Ntl 77-M

Electronic Hygrostat Adjustable and pre-set relative humidity Temperature-compensated NTL 77-M (NTL 77)
• Adjustable and pre-set relative humidity
• Status indicator (LED)
• High switching capacity
• Clip fxing
• Temperature-compensated
The electronic hygrostat senses the relative humidity in an enclosure with electric/electronic components and turns
on a heater at the set point, helping prevent the formation of condensation in the enclosure. The LED integrated in the
adjustment knob is lit when the connected heater is in operation.
