Scott, does the calibration change if one removes the yellow metering tip? I realize it cuts the dilution in half but what about calibration?Any in-line sprayer will cavitate resulting in inaccurate dilution ration as it gets closer to boiling. Depending upon your elevation, the temperature at which this starts to happen will vary from 180 F to 200 F. Stay below the cavitation temperature.
Pressure depends upon the specific model of sprayer and the valve. The Hydro_force in-line sprayers are calibrated at 400 PSI. Dilution ratio will be most accurate at that PSI.
It can be used at anywhere from 100 to 1000 PSI and the spray gun itself is rated at 2700 PSI.
Remember that the ATW temp is usually about 30-40º less than ATM temp. And why not just pre-spray the house at idle or 1/2 throttle?My truckmount heats too quickly to keep it under 200 degrees. So if I spray a room at 220 or 230, does it not draw enough chemical?
The dilution goes from 1:8 to 1:4 when the metering tip is removed. You could put the yellow tip back in and be back at the original calibration / dilution.Scott, does the calibration change if one removes the yellow metering tip? I realize it cuts the dilution in half but what about calibration?
The Hydro-Force in-line sprayers use an 8006 Veejet as the spray tip. Products from different vendors may have different valves or be calibrated differently. The 8006 is the ideal size for a variety of products to be sprayed and stay near the most accurate dilution rate.
