Low Ownership Cost HCN Gas Detector Single Gas Detector with Replaceable Sensor and Replaceable Battery for Toxic Exposure Protection

MiniMeta is an IECEX/ATEX/EMC certified single-gas detector. It Can detect hundreds of user-selected toxic gases, user friendly and easy for operation. The battery and sensor is replaceable to provide user a long term protection. It is designed to offer a low long-term ownership cost of a gas monitoring system.

Hydrogen cyanide represents an extremely dangerous occupational hazard; many individuals lack the ability to detect its characteristic bitter-almond odour by smell alone, making continuous instrument-based monitoring essential for worker safety. This diffusion-sampling unit adopts an electrochemical HCN sensor with configurable measuring ranges of 0-10 ppm, 0-50 ppm, 0-100 ppm and selectable resolution of either 0.01 ppm or 0.1 ppm.

• IECEx, ATEX, EMC certification for deployment inside hazardous explosive-atmosphere locations
• Explosion-proof classification: Ex ia IIC T4 Ga
• IP68 rating: complete dust protection and temporary submersion capability

• Target gas: Hydrogen Cyanide (HCN)
• Available measuring ranges: 0-10 ppm, 0-50 ppm, 0-100 ppm
• Selectable resolution: 0.01 ppm / 0.1 ppm
• Detection principle: Electrochemical sensor, diffusion-type sampling (no pump)
• Accuracy: ≤ ±2-5 %FS (sensor-dependent)
• T90 response time: 15-30 seconds

• Supply: 3.6 V field-replaceable non-rechargeable dry battery
• Standby operating lifespan: up to 2-years; no charging required during service cycle

• Alarm outputs: 95 dB@30 cm acoustic buzzer, dual high-brightness red LED lamps, vibration alert
• Supported alarm categories: Low concentration, high concentration, STEL, TWA, low-battery reminder; also flags upcoming calibration-due and bump-test-due status

• Operating temperature range: -20 °C ~ +55 °C
• Operating humidity: 0-95 %RH (non-condensing environment only)
• Working air pressure: 86-106 kPa
• Total weight: 125 g including back clip and battery
• Outer dimensions: 90*60*33 mm; supplied with back-clip for garment attachment

• Automatic startup self-test for sensor and battery condition
• Optional event-history data-logging capability
• Optional single-unit or multi-position docking-station for bump-test and calibration workflows
• Visual read-out supports real-time readings plus TWA, STEL, MAX and MIN calculated exposure values; screen displays gas identity, numerical value, concentration unit and remaining battery charge

1. Rugged Field-Proven Construction IP68 dust-and-water-tight enclosure tolerates harsh outdoor and plant-floor industrial environments. Meets Ex ia IIC T4 Ga intrinsic-safety standards for classified hazardous-area deployment.

2. Extended Service Cycle, Minimal Power Management Single 3.6 V dry-cell supports up to two-year standby runtime. Charging infrastructure is unnecessary; end-users swap batteries directly on-site.

3. Streamlined Maintenance Workflow No compulsory frequent calibration over the two-year standby operating window. User-swappable sensor module extends instrument usable lifespan. Optional docking-station streamlines scheduled bump-test and calibration operations.

4. Multi-Modal Clear Hazard Notification Combination buzzer, dual-LED visual indicators and vibration guarantee warning perception even within noisy industrial surroundings. Screen simultaneously presents instantaneous readings plus occupational-safety metrics including TWA, STEL, MAX and MIN.

5. Light-Weight Wearable Ergonomic Form Compact footprint at just 125 g inclusive of clip and battery. Integrated back-clip enables convenient fastening to work clothing or safety-harness straps.

Optional accessories: bump-test & calibration docking-station, event-data-logging functional module.

Q1: What target gas is this MiniMeta unit configured for?

A: This instrument is purpose-configured for hydrogen-cyanide (HCN). Alternative sensor cartridges for numerous other toxic gases can be fitted on request.

Q2: What measuring ranges and resolution choices exist for HCN measurement?

A: Available measuring ranges:0-10 ppm, 0-50 ppm, 0-100 ppm. Resolution options:0.01 ppm or 0.1 ppm, selected at time of ordering.

Q3: What sampling method does this detector adopt?

A: Pure diffusion-based sampling; there is no built-in sampling pump.

Q4: What are the explosion-proof and environmental-protection ratings?

A: Explosion-proof level Ex ia IIC T4 Ga; IP68 dust-proof and water-proof rating.

Q5: What battery type is used and what runtime can users expect?

A: 3.6 V non-rechargeable field-replaceable dry battery; maximum standby runtime reaches two-years, no charging needed.

Q6: Is docking-station hardware included within standard delivery scope?

A: Docking-station for bump-testing and calibration is sold separately as optional accessory.

Q7: Can the unit record historical measurement events?

A: Event-logging function belongs to optional upgrade and is not pre-installed by factory default.

Q8: What alarm types does MiniMeta HCN support?

A: It provides sound, dual-LED light and vibration alerts; alarm items cover low/high gas concentration, STEL, TWA, low battery, plus upcoming calibration and bump-test reminders.
