Professional Wireless HVAC Thermometer and Humidity Sensors
Monitor up to 3 Indoor HVAC Zones and Outdoor Temperature from AC Unit Work Area!
HVAC Signal professional wireless thermometers help HVAC technicians service residential and commercial refrigeration and heating jobs quicker and safer.
HVAC technicians can work faster and safer on large and small residential homes, multi-family units, multi-floor commercial office buildings. Poor performing vents can be evaluated and diagnosed. Service calls require fewer ladder climbs, entry and exits of buildings, less customer disturbance, and fewer footprints on customer flooring.
Technicians easily hang wireless thermometers directly on indoor vents and carry the main display thermometer to the rooftop or ground-level condenser unit to monitor indoor temperatures. Technicians can check up to three indoor zones’ supply or intake vents. Indoor, outdoor temperatures and humidity are displayed on the main display in real-time as adjustments are made.
Wireless thermometer range is up to 330 feet depending on construction. No short-range Bluetooth connections or software issues. Thermometers are battery operated with no recharging downtime.
