Micro Matic Co2 Pressure Tester

  • $136.49

If you want 100% accuracy on your CO2 regulator gauges, use this Micro Matic Pressure Tester. You rely on an accurate thermometer for measuring the temperature while making your homebrew and having accurate pressure gauges for dispensing your beer should be no different.

Procedures as Outlined by Micro Matic:

Step A. Check System for Pressure Leaks
Prior to utilizing tester, check the system for pressure leaks and repair. Regulators do malfunction and gauge readings are inconsistent when leaks are present.

Step B. Reset Gauge Pointer to Zero
If the tester's gauge pointer is not reading at zero, remove the cover from the faceplate and place thumb and index finger on each side of the pointer close to the pivot point (hub). Place a small screwdriver in the slot at the pointer's hub and lightly turn against thumb and finger. Release pointer and repeat or reverse adjustment until pointer rests at zero. Replace the cover on the faceplate. The tool is now ready to be applied to the dispensing system.

Step C. Testing
The tester can be attached directly to either a "D" or "S" style coupler with the adapter or it can be attached directly to a shut off from a regulator or gas distributor.

Testing from Regulator
For testing from a shut-off, place the open end of the 5/16" ID vinyl from the tester and attach directly to the barbs of the shut-off from a distributor or regulator. Assure that the tester's shut off is open to the 5/16" line and closed going to the coupler adapter on the other side.

Testing from Coupler
To read pressure directly at the coupler, engage directly onto the tester's adapter. Assure that the shut off feeding this side is open while the opposite shut off to the 5/16" line is closed.

With the tool attached in either method, apply pressure from the regulator. If the regulator gauge reading is inaccurate or unreadable, adjust the regulator to the tester's gauge. Replace or repair regulator gauge/regulator if required. To prevent beer from entering the tester's gauge, attempt to keep the gauge upright while utilizing with coupler adapter.
