The multi-channel concrete maturity meter used to determine the earliest safe removal of concrete forms and shoring in the field. Displays both concrete temperature and maturity number simultaneously and the four channels can be used together. All information is available on the menu driven alphanumeric display. The meter utilizes inexpensive, quick connecting T type thermocouple wire. The datum temperature is programmable from -20°C to 50°C (-12°F to +122°F). A waterproof communications port allows information transfer from meter to meter, printer, or computer. The C6221 is similar to the C6211 meter except that a rechargeable nickel-cadmium battery is used. A waterproof battery charge connector enables charging from the 120V charger supplied or run directly off of AC power. This unit provides improved low ambient service temperature performance.
