Answer:
ERP lists approx. 410 × 140 mm dimensions and a 280 g net weight without battery; the product weight field remains 0.37 kg. ERP also lists 9V or rechargeable NiCd power, 40 h / 14 h operation at 10% alarm time, and 14 h recharge.
ERP describes the SMD-100 as approximately 410 × 140 mm and approximately 280 g without battery. The ERP product weight field remains 0.37 kg; the net-weight note is kept distinct. ERP lists standard 9V or rechargeable NiCd power, up to 40 h or 14 h operation respectively at a 10% alarm duty cycle, a 14 h recharge time, and 0–95% non-condensing relative humidity.
