What Probes do I Need?

What Probes do I Need?

When most of our users start out with our platform, they primarily begin with A/C testing, then expand into furnace testing, so I will start with the required probes needed for A/C to start, then add additional probes required for Heat Pumps and Furnaces.

Required A/C or Heat Pump Cooling Probes:
  1. Low Pressure
  2. High Pressure
  3. Suction Line Temp
  4. Liquid Line Temp
  5. Outdoor Air Temp
  6. Return Air Psychrometer
  7. Supply Air Psychrometer
  8. Return Air Static Pressure (RESP) Manometer*
  9. Supply Air Static Pressure (SESP) Manometer*
            *One dual port manometer can be substituted for probes 8 & 9 however it can only display Total External             Static Pressure (TESP). It cannot isolate supply and return measurements, rather it calculates the total             difference between the two.

Required Heat Pump Heating Probes:
All A/C probes plus the following:
  1. Vapor Line Temp*
            *Can also be used in cooling mode on the Discharge Line

Required Furnace Probes:
  1. Return Air Temp Probe (from A/C List)
  2. Supply Air Temp Probe (from A/C List)
  3. Static Pressure Manometers (from the A/C List 8 & 9*)
  4. Incoming Gas Pressure Manometer
  5. Manifold Gas Pressure Manometer
  6. Combustion Analyzer
Optional Furnace Probes:
  1. Induced Draft Pressure Manometer
  2. TEC DG-8 Manometer for Combustion Air Zone (CAZ) Pressure Testing.*
    *Fieldpiece, Testo, and Yellow Jacket probes are not sensitive enough for this measurement.
