Automatic Universal Penetrometer delivers precise, automated sensitive measurements. The machine-grooved aluminum base has 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 standard 1/8in (3mm) diameter stem may be mounted to the 47.5g plunger assembly. The penetrometer is supplied with a standard 2.5g ASTM D 5 Needle and two additional Loading Weights (50g and 100g).
HM-322 model features a button release mechanism with a digital timer to automatically stop the plunger when the preset time from 0.1—9.9 seconds expires. Indicator dial is graduated in 400 divisions of 0.1mm, corresponding to 40mm penetration.
HM-322D model is based on the HM-320 and HM-322 Penetrometers but uses a digital penetration gauge for precise readings. This model will also start the test with the push of a single button and stop it after a preset duration.
