Note:
1.The measuring range within 20-300SLM.
2.SLM means standard liter per minute. Standard-state: gas temperature is 0ºC and pressure is 101.325 kPa. The testing environment is room temperature and clear air.
3.The response time could be customized for 15-1000ms.
4.The temperature compensation is for the tem. range of 0-50ºC and the compensation performance can't be ensured beyond the temperature range.
