TEC DG-8 Digital Pressure Gauge — Micro-Manometer for Radon Diagnostics

Professional-grade single-channel micro-manometer from The Energy Conservatory (TEC), designed for the field measurement work that C-NRPP-certified mitigators do every day: verifying sub-slab pressure field extension, sizing fans, troubleshooting weak systems, and confirming system performance after install.

Why mitigators carry a DG-8

• 0.1 Pascal resolution — fine enough to measure the small pressure differentials that drive sub-slab depressurization
• Standalone operation — no blower door required, no laptop required, no wires beyond the tubing
• Color LCD display — readable in dim basements and bright attics
• Rechargeable battery — no AA changes between jobs
• Mobile app integration — free TEC Gauge app for iOS and Android lets you log readings, capture screenshots, and share results with clients
• Firmware-updatable — stays current with TEC software improvements

Field uses

• Pressure field extension (PFE) testing through test holes during diagnostics
• Post-install verification of sub-slab vacuum at the suction point and remote test holes
• Fan sizing — measuring fan-side pressure to confirm fan selection
• Troubleshooting a system that won't bring radon down — finding the leak or short-circuit
• Building diagnostics beyond radon — zone pressures, duct leakage spot checks

Made for the field

The DG-8 is the professional micro-manometer that radon mitigators, energy auditors, and HVAC commissioners actually carry on the truck. Compact enough to fit in a tool bag, rugged enough for daily field use.
