The SH5508B Toxicity Testing Chamber is designed in compliance with the British Navel Engineering Standard NES 713. It is applicable for the toxicity assessment test of small specimens, such as wires and cables.
The SH5508B Toxicity Testing Chamber is designed in compliance with the British Navel Engineering StandardNES 713.It is applicable for the toxicity assessment test of small specimens, such as wires and cables.
The chamber is an integrated test apparatus combining thefunction ofsampleholding, sample combustion, programmable control, gas mixing and gas samplingaltogether in one machine, endowing the machine with a compact structure and user-friendly operation pattern.
With the gas analytical equipment (colorimetric gas reaction tubes / gas analyzer) the operator is capable to analyze the concentration(ppm) of certain toxicity gas, and subsequently calculate the toxicity index of the test specimen.
