We present the measurements of scatter broadening timescales (τ_SC) for 124 pulsars at 327 MHz using the upgraded Ooty Radio Telescope. These pulsars lie in the dispersion measure range of 37-503 pc/cm3 and declination (δ) range of -57°< σ < 60°. New τ_SC estimates for 58 pulsars are presented, increasing the sample of all such measurements by about 40% at 327 MHz. Using all available τ_SC measurements in the literature, we investigate the dependence of τ_SC on dispersion measure. Our measurements, together with previously reported values for τ_SC, affirm that the ionized interstellar medium up to 3 kpc is consistent with the Kolmogorov spectrum, while it deviates significantly beyond this distance.
