Description:
- SO₂ and NO₂ adopt independent high-selectivity electrochemical sensors, effectively reduce cross interference of mixed acid flue gas, accurately quantify acidic gaseous pollutants from boiler, cement kiln and incinerator exhaust;
- PM2.5 & PM10 adopt high-precision laser scattering particle sensor, synchronously measure inhalable dust concentration in flue gas and factory ambient environment.
It supports standard diffusion sampling and optional 1L/min pump suction sampling for deep flue pipeline sampling. Equipped with LCD screen to synchronously display all gas and particle concentration, unit and alarm status, stores up to 9999 groups of test records for environmental emission filing and pollution source traceability.
With Ex ib IIB T3 explosion-proof grade and IP65 dustproof & waterproof shell, only 300g lightweight handheld design, 100 hours long standby under diffusion mode. Widely applied in thermal power boilers, cement kilns, waste incineration plants, smelting factories and environmental law enforcement flue gas dust spot check.
Features:
- Detects 1–5 gases simultaneously
- Compatible with electrochemical, NDIR, PID, and semiconductor sensors
- Flexible gas configuration for different detection environments
- Pump suction or diffusion sampling mode (optional)
- LCD display showing gas concentration, gas type, and alarm status
- High-precision imported sensors for accurate measurement
- Built-in self calibration and zero calibration functions
- Temperature and pressure compensation for reliable readings
- Two-level alarm system: sound, light, and vibration
- Adjustable alarm set points
- One-key factory reset function
- Large capacity rechargeable lithium polymer battery
- Durable PC + TPE housing: anti-slip, waterproof, dustproof, explosion-proof
- Stainless steel filter for better gas flow and sensor protection
