The Riken Keiki SD-1EC Smart Transmitter/ Gas Detector line of smart transmitters features state-of-the-art gas detectors with durable flameproof enclosure, best operability and maximum safety, especially in hydrogen/acethylene atmospheres. A simple magnetic control key is placed over clear marked positions on the surface plate to test and adjust the instrument without opening the transmitter in situations with the danger of explosion. This œsingle-man-calibration is already in use and appreciated with other Reken Keiki gas detectors for easy maintenance. The built-in microprocessor features self-diagnosis functions and automatic zero setting to minimise maintenance work and costs compared to other sensors. Dual alarm contacts or trouble alarm contact are provided for activation of external buzzer or alarm light. Powered by 24VDC, the unit has a 4-20mA output for communication to external controllers, for external readouts or alarming devices.

The Riken Keiki CO-03 personal single gas monitor is developed to protect users against carbon monoxide (CO) gas types. The Riken Keiki CO-03 has a gas- and trouble alarm detection, with a detection range of 0-500ppm (1ppm). Both will be displayed throughout flashing light, buzzer and vibration.

The Riken Keiki GX-3R is the smallest and lightest 4 Gas Confined Space gas detector available today. With a size of 58 mm wide, 65 mm high and weighing 100g, the Riken Keiki GX-3R gas detector can be defined as true craftsmanship. The Riken Keiki GX-3R is perfect for confined space work as its size means it does not interfere with work even if it is attached in the breathing zone. Battery Life: The Riken Keiki GX-3R gas detector has a build-in extended battery mode which allows the monitor to be used continuously for up to 40 hours before recharging. IP66/68 compliance, as well as a three-year sensor warranty, allows the Riken Keiki GX-3R to be used with confidence. Alarm: The GX-3R has 3 preset alarm settings per gas and an over alarm which allows the alarms to be set at EH40 workplace exposure limits plus an additional alarm for a higher detection range. The GX-3R internal data logger allows 3600 event logs and 300 hours which can be read out using an IrDA link. A loud 95dB alarms buzzer is also included. Operating temperature range: The Riken Keiki GX-3R has an operating temperature range of -40 degrees Celcius to +60 degrees Celcius (intermittent) or -20 degrees Celcius +50 degrees Celcius (continuous) allowing the GX-3R to be used in many different environments and applications. The GX-3R uses 3 compact sensors including a brand new Electrochemical Oxygen Sensor. The Riken Keiki GX-3R Confined Space Monitor will detect, Combustibles, Hydrogen Sulphide, Oxygen as well as Carbon Monoxide. A 3-year sensor warranty is now standard.
