Specifications
SKU: ERANNTEX Portable Pump-Suction Laser Methane Detector
The Eranntex BTYQ-MS500-CH4-TDLAS portable pump-suction laser methane detector is equipped with a multi-dimensional alarm system, including audible and visual alarms, visual alarms, combined audible and visual alarms, and vibration alarms. Alarm types cover concentration exceeding the specified limit, battery undervoltage, and system failure, and support low limit, high limit, range, and weighted average alarm modes. The device features a built-in factory reset function, automatic zero tracking technology to eliminate the effects of long-term drift, supports a multi-level calibration process, and automatically identifies and prevents concentration calibration errors. An optional ambient temperature and humidity measurement module is available, and a custom RS485 communication interface is available. Other functions and communication protocols can be developed upon request, and OEM/ODM customization services are also available.
