TEC - Model DG-8 -Digital Pressure Gauge

Digital TrueFlow® Solution
The DG-8 is a key component of the Digital TrueFlow® solution and provides static pressure readings which are used in two ways:

1. Supply plenum pressure with the HVAC system filter in place and then with the TrueFlow® Grid – to adjust the raw flow reading from the Digital TrueFlow® to deliver excellent flow rate accuracy in the specific system being measured.
2. Additional static pressures in the system (Supply, Return, and entrance and exit of air handler/furnace) to diagnose the root-cause of low system air flow.

The DG-8 and Digital TrueFlow® Grid connect by Bluetooth® to the TEC TrueFlow® App to take measurements and provide the system diagnosis. Download the free TEC TrueFlow® App on your Android or iOS device.

• Accurate Readings at 0.9%: Upholds your confidence of accurate results from TEC equipment
• Easy-to-read Color Display: Easily toggle measurements between in. H2O and Pascals
• Lithium Battery: Equips you with a rechargeable power source on the job
• Texturized Durable Case: Ensures optimal grip in rugged environments and protects your gauge from accidental damage
• Powerful Mounting Magnets: Provides dependable and convenient mounting options
• Bluetooth® Communication: Connect to the TEC TrueFlow® or TEC Gauge app on your Android or iOS device

The DG-8 is a highly accurate single-channel micromanometer, and it is intended for use beyond the TrueFlow® – including in key building pressure measurements, such as room pressures, zonal pressures, Exhaust Fan Flow Meter, Pressure Pans, CAZ depressurization testing, radon sub-slab, hospital room pressure, and many more.
