China Electronic Hygrotherm Temperature Humidity Integration Adjustable Temperature Humidity Ntl 78-M

Electronic Hygrotherm Temperature and humidity integration Adjustable temperature and humidity NTL 78-M (NTL 78)
• Temperature and humidity adjustable
• Wide voltage range
• Operating temperature down to -40°C
• High switching capacity
• Status indicator (LED)
The electronic hygrotherm senses the ambient temperature and relative humidity in an enclosure with electric/
electronic components and turns on a heater (or alternatively a fan) at either set point, helping prevent the formation
of condensation in the enclosure. Due to its wide voltage range the hygrotherm can be utilised anywhere in the
world.  The LED integrated in the adjustment knob on the active controller is lit when the connected device is in
operation.
