洪堡's 电动贯入仪, takes our H-1200 universal penetrometer and adds an automatic digital timer to it. The timer's release mechanism is switchable between seconds minutes, or hours. Timer may be set in 1/10th second intervals. Plunger releases with push of a button, and automatically stops after the preset time duration. H-1240.4F adds a voltage adapter and internal switch on the timing mechanism to change cycle to 50Hz.
This unit has a machine-grooved aluminum base, built-in leveling screws fitted with rubber inserts to protect needle and cone tips. Two stainless steel rods support the cast aluminum head with coarse/fine adjustments. A button release mechanism with a digital timer automatically stops the plunger when the preset time from 0.1–9.9 seconds expires and the indicator can be instantly reset to zero. Any needle or cone with a standard 1/8in (3mm) diameter stem may be mounted to the 47.5g柱塞总成. The penetrometer is supplied with a standard 2.5g ASTM D 5 Needle and two additional Loading Weights (50g and 100g).
