PortaCount Fit Test Probe Refill Kit

50x "Probes", 50x "Push Nuts" made by TSI for your PortaCounting needs! Packaged in resealable bags. 

Years ago when I was first sourcing a used PortaCount, one of the hardest things to find was probes. I lucked out at the time, but really really wished someone sold a smaller pack than 500 for less than hundreds of dollars. Here we are in the future, and we've done just that! 

Need an installer tool? I've got you!

These are re-packaged by weight with a high precision scale, but is worth noting that the count per bag may be slightly off, since we are doing this small scale and by hand. Thank you for understanding :)
