Chlorine detector
Thread Content
Dear sea friends, according to Article 3.10 of the GB11984 Safety Regulations for Chlorine, the maximum allowable concentration of chlorine in areas where it is used is 1 milligram per cubic meter, which is equivalent to 0.34 ppm. The alarm accuracy of our company’s devices does not meet this requirement. Could anyone recommend manufacturers that produce alarms with such high precision?
For chlorine concentration, the range is 0–5 ppm; for the first and second levels, alarm values of 0.5 and 1 can be set accordingly.
Such a setting does not meet **standard requirements.
So, have you found the product? This figure wasn’t just guessed randomly.

It wasn’t found. Previously, an evaluation agency brought up the issue of setting this alarm value to us, and we also consulted the manufacturers that produce chlorine alarms; they issued a certificate stating that no such product can be manufactured in the industry； However, I think that since there is the **standard GB11984, we should follow it; otherwise, what’s the point of having such a standard? If no one can meet it, it’s better to abolish it. The concern here is that some of the experts in charge of the inspections will stick rigidly to the standards and not give in, making it difficult for us to make the necessary adjustments……
Because this is a standard, it’s impossible to take all substances into account; this time it’s Zhang San, next time it’s Li Si, and it will go on like this indefinitely.
The source of the data mentioned by this brother has been found. This requirement is specified in both the \"Safety Design Standards for Caustic Soda Plants T/HGJ 10600-2019\" and the \"TCCASC1003-2021 General Technical Requirements for Safety Facilities for Chlorine Production in Chlor-alkali Plants\".
Yes! Since I come from the chlor-alkali industry, I have some knowledge in this area; with such a design, it can be manufactured by any detector manufacturer available on the market today.
