The Riken Keiki model SC-8000 is a single toxic gas detector, built for tough environments. It’s durability sets a new standard for rugged, reliable, portable toxic gas detection. This robust, yet lightweight, sample drawing monitor is designed to provide continuous exposure monitoring in safe or hazardous areas.

Its large LCD display makes reading the SC-8000 easy, even when the operator is wearing a hazmat suit.

For loud environments the unit is equipped with a 95dB alarm that alternates between a high & low pitch so the alarm can be heard in noisy places. This, together with three bright LED lamps make the SC-8000 alarms very noticeable.

The unit is intrinsically safe for hazardous areas and designed to be waterproof to IP67. In all, making the SC-8000 an extremely rugged unit for the most demanding situations.

Some of the most common toxic gases the SC-8000 will detect are Silane (SiH4), Phosphine (PH3), Arsine (AsH3), Ammonia (NH3), Hydrogen Chloride (HCl), Chlorine (Cl2) and Hydrogen Fluoride (HF), plus many others.
