Description:
OC-850 portable multi gas detector is a customizable handheld air safety detector, configured dual core sensor combination: O₂ Oxygen , CH₂O Formaldehyde.
Both O2 and CH2O adopt independent high-selectivity electrochemical sensors, effectively reduce cross-interference between oxygen and formaldehyde gas, accurately detect oxygen concentration and formaldehyde volatile gas released from paint, furniture, adhesive after decoration.
This detector supports dual sampling modes: standard diffusion passive sampling and optional 1L/min pump suction active sampling, convenient for closed wardrobe, cabinet, newly renovated room, workshop interior gas extraction. Built-in stainless steel filter screen filters dust and floating particles to protect internal sensors. Clear LCD screen synchronously displays real-time O2 & CH2O concentration, gas name and over-limit alarm status.
It holds Ex ib IIB T3 explosion-proof certification and IP65 dustproof & waterproof rating, triple sound-light-vibration over-limit alarm, stores up to 9999 groups alarm records. Wide working temperature -40℃~70℃, 100 hours long standby without pump. Widely used in new decoration residential houses, office buildings, furniture factories, paint workshops, indoor environmental acceptance and daily indoor air quality inspection.
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
