The models measure HC, CO, CO2, O2, and NOx. The specific measurement capabilities depend on the model choice (e.g., BK-EA201 measures HC and CO, while BK-EA501 measures all five gases).
Yes, the gas analyzer comes equipped with a built-in printer for instant data documentation, along with a high-brightness digital display.
The standard preheating time is 8 minutes. For urgent needs, it supports a fast 3-minute emergency detection preheating cycle.
The device is highly responsive, with a 95% response rate achieved in no more than 10 seconds.
The unit is compatible with AC 110V/220V ±10%, operating at standard frequencies of 50Hz or 60Hz.
Yes, the system is designed with an automatic zero calibration, linear data processing, and a built-in alarm that triggers instantly when the gas path is blocked.
