HD32.8 Series Inputs Temperature Data Logger – Thermocouples

Brand: Delta OHM S.R.L.

Rugged data logger with 8 inputs for K, J, T, N, R, S, B and E type thermocouple with miniature connector temperature probes.

Use of data loggers HD32.8.8 and HD32.8.16: in field for measurement campaigns on complex systems with many measurement points, testing facilities, in pharmaceutical and food sectors, ovens mapping, air conditioning centrals etc.
Features
  • Unit of measurement °C, °F, °K configurable.
  • Flash memory organized in 64 sections with a total capacity of 800.000 acquisitions to be divided among all the present inputs. 
  • Storage can be managed in two ways
    • When the available memory is full, data are overwritten by starting from the oldest ones (circular memory)
    • Storage stops when the available memory is full.
  • Simultaneous display in group of 4.
