✅【 4 in 1 Specialist Gas Detector】 The 9000A detects carbon monoxide (CO), oxygen(O₂), hydrogen sulphide (H₂S) and explosive gases(EX).
✅【 Three alarm modes】 sound, light and vibration. The gas detector can set alarm thresholds based on the actual gas detected. It can also store up to 3000 alarm records.
✅【 Accurate Gas Leak Detector】
The Gas Monitor measures Oxygen from 0-30% VOL with a ±5% FS tolerance,
Hydrogen Sulphide from 0-100 PPM with a ±10% FS tolerance;
It measures carbon monoxide over a range of 0-1000 PPM with a ±10% tolerance.
Finally, it detects combustible gases over a range of 0-100% LEL, with a display error of ±5% FS.
✅【 Large Color LCD Display】 2.8" colour display, menu navigation with 3 buttons, 3000 alarm logs can be stored.
✅【 Portable CO Detector】 this gas detect









✅ Warm tips about charging:The battery socket in our Gas Detector is unplugged, and the customer needs to open the battery cover and plug in the battery.
Descriptions:
- Professional 4-in-1 Gas Detector: The natural gas leak detector combines electrochemical and catalytic sensors to monitor O2/CO/EX/H2S Gas Levels (0-30%VOL O2, 0-100%LEL EX). Perfect for Home & Industrial Safety in Confined Spaces or Indoor Air Quality (IAQ) Assessments. ±5% minimum accuracy ensures reliable natural gas detector performance.
- Triple Alerts: The Natural Gas Leak Alarm has three alarm modes: sound, light and vibration. The gas detector can set the alarm threshold according to the actual detected gas. When the safety value is exceeded, the gas leak detector alarm can store 3000 sets of alarm records.
- Accurate measurement: The measurable range of hydrogen sulfide and carbon monoxide in the gas detector can reach 0-100PPM, ±5% minimum accuracy ensures reliable gas detector for natural gas leak detection performance.
- Large Color LCD Display 2.8" colour display, menu navigation with 3 buttons, 3000 alarm logs can be stored.
- Smart Gas Detector: Portable gas leak detector provides more than 8 hours of battery life and has an automatic shutdown function. T<45 seconds response time prevents carbon monoxide poisoning and combustible gas explosion.
- Home and Industrial Use: Natural gas leak detector can be used in home basements, kitchens or industrial sites, and can detect natural gas/carbon monoxide/hydrogen sulfide in garages, furnace rooms or sewage treatment plants, it can also be used as an indoor air quality detector
✅Tips of Gas Leak Detector: Do not use corrosive solvents and hard objects to clean this air quality monitor, which may cause damage to the surface and sensor. If the combustible gas sensor has been exposed to sulphur compounds, silica vapours, halogen compounds, etc., it is recommended that it be calibrated with a known concentration of standard gas.
