What is the allowable range for the zero offset value of flammable and toxic gas detectors? Are there any standards?
Section 5.2.2 of the explanatory notes for GBT50493-2019 states:
The allowable range for the zero offset value of flammable and toxic alarms depends on the specifications of the specific product and manufacturer. Generally, under normal conditions, the zero offset should be kept within ±5%. For the exact standards, please refer to the product manual or contact the manufacturer for more detailed specifications. Standards such as GB15322.1 may also provide some guidance. .
