4-Channel Concrete Maturity Meters

Four-Channel Concrete Maturity Meters have internal memory for continuous recording of half-hour readings. Datum temperature and activation energy are user programmable. One to four locations can be monitored at once, and channels are accessed via membrane keyboard and alphanumeric display. Maturity progress can be checked directly from the meter at any time. The Type T thermocouple wires have quick connect jacks for direct embedding into a concrete structure to measure temperature at specific intervals. Memory capacity is 32K. Both meters include Type T thermocouple wire, four connectors, RS-232 cable for downloading to a PC, and a plastic carrying case.

HM-136 is operated by included 9V lithium battery for three weeks or more.

HM-134 has the same capabilities, but is rechargeable and comes with a NiCad battery and charger to more than double battery life or permit operation from 115V AC.
