Explosion-proof Calorimeter

OHC-800

Features

・“Opt-Sonic calculation” is applied by using Optical sensor
　and Sonic sensor.
・Easy to switch the display among "Calorific value", "Density"
　and "WOBBE index".
・Fulfilling self-diagnosis function and running cost.
・Body structure that can be installed into all types of
　location.
