MiniMeta 2-Year Maintenance-Free IP68 Waterproof Gas Detector for Chlorine (CL₂) with Triple Alarm

A compact, IECEx/ATEX/EMC certified single-gas detector for chlorine (CL₂) monitoring. Measures 0–10ppm (0–20/50/100ppm also available) with 0.01ppm resolution using an electrochemical sensor. Features IP68 waterproof/dustproof, 2-year standby time on a single replaceable dry battery, triple alarm (95dB buzzer + 2 red LEDs + vibration), replaceable battery & sensor, and self-test function. Ideal for water treatment, chemical industry, and swimming pool safety.

The MiniMeta is an IECEx/ATEX/EMC certified portable single-gas detector designed for long-term, low-cost ownership. It operates on a 3.6V dry battery (non-rechargeable, replaceable) with a 2-year standby time – no charging and no calibration required during this period. The battery and sensor are both replaceable, extending the device's service life.

Taking chlorine (CL₂) as an example, the MiniMeta uses an electrochemical sensor to measure concentrations. Standard ranges include 0–10ppm, 0–20ppm, 0–50ppm, or 0–100ppm with a resolution of 0.01ppm. Accuracy is ≤ ±2–5% FS, with a response time (T90) of 15–30 seconds.

The detector features three simultaneous alarm modes: 95dB buzzer (@30cm), 2 high-brightness red LEDs, and vibration alarm. Users can set low/high alarm thresholds, STEL, TWA, and receive low battery, calibration due, and bump test due alerts. The LCD display shows gas name, concentration, unit, and battery power, along with real-time value, TWA, STEL, MAX, and MIN.

The MiniMeta includes a self-test function that automatically verifies sensor and circuit integrity on power-up, improving safety. It also features a back clip for easy carrying.

Chlorine is a greenish-yellow, highly reactive gas with a pungent, bleach-like odor. It is widely used as a disinfectant in water and wastewater treatment, in the production of PVC and other chemicals, and in swimming pool sanitation. Chlorine is highly toxic: even low concentrations cause eye and respiratory irritation; higher concentrations can cause pulmonary edema and death. Because chlorine is heavier than air, it accumulates in low-lying areas, making continuous monitoring essential for worker safety.
