The experimental observable properties of the triplet $p_z$-wave pairingstate, proposed by Wu {\em et al.} [arXiv:1503.06707] in quasi-one dimensionalA$_2$Cr$_3$As$_3$ materials, are theoretically investigated. This pairing stateis characterized by the line nodes on the $k_z=0$ plane on the Fermi surfaces.Based on the three-band tight binding model, we obtain the specific heat,superfluid density, Knight shift and spin relaxation rate and find that allthese properties at low temperature ($T\ll T_c$) show powerlaw behaviors andare consistent available experiments. Particularly, the superfluid densitydetermined by the $p_z$-wave pairing state in this quasi-one dimensional systemis anisotropic: the in-plane superfluid density varies as$\Delta\rho_{\parallel}\sim T$ but the out-plane one varies as$\Delta\rho_{\perp}\sim T^3$ at low temperature. The anisotropic upper criticalfield reported in experiment is consistent with the $S_z=0$ (i.e.,$(\uparrow\downarrow+\downarrow\uparrow)$) $p_z$-wave pairing state. We alsosuggest the phase-sensitive dc-SQUID measurements to pin down the triplet$p_z$-wave pairing state.
