KAQ-57OA KEPLER O2 Fixed Gas Detector

Details of KEPLER Oxygen (O2) Gas Detector Model KAQ-57OA

The KEPLER Oxygen (O2) Gas Detector, model KAQ-57OA, is an oxygen gas detector that displays measurement results on a 7-Segment display with 4 digits. It comes equipped with an IR Remote for setting and calibration purposes. Additionally, it features three LED lights which illuminate when the measured value exceeds Low alarm or High alarm levels. The device is robust, meeting explosion-proof standards and constructed from aluminum alloy material. It also provides an analog output of 4~20 mA.

This sensor can be used for workplace safety to prevent hazards such as oxygen deficiency, toxic substances, poisonous gases, confined spaces, and flammable gas explosions. It is suitable for various industrial applications including steel mills, oil industries, petrochemicals, shipbuilding, wastewater treatment plants, mines, power stations, etc.
