73-0040RK-03 Gaswatch 2, Model GW2X Single Gas Personal Monitor, 0 - 40% vol. O2 with Watch Band by RKI Instruments
RKI Instruments utilizes the latest technology and research to develop a wide range of workplace safety products. As an industry leader in advanced micro sensor technology, their designs are typically compact, efficient, and affordable. The company has a long-standing track record for innovative technologies and their robust research and development team is constantly seeking new ways to meet the needs of hazardous jobsites. The new GasWatch 2 by RKI Instruments is paving the way for workplace safety products. Its compact design and high portability ensure that the device is always accessible and its dependence on advanced technology guarantees its reliability and accuracy.
GasWatch 2
The GasWatch 2 features an easy and convenient method for monitoring single gases. With three gases to choose from (carbon monoxide, oxygen, and hydrogen sulfide), users can receive a fast and accurate response. Each individual gas sensor is color coded for quick reference and convenience. The unique space saving device fits directly on the wrist similar to a watch. The hands free device monitors the environment for the atmospheric condition and alerts the wearer in accordance with its settings. Its micro sensors use galvanic and electrochemical technology to monitor the air quality. They are inexpensive and are made to be easily replaced while in the field. They also have a life expectancy of over 2 years.
Features
The GasWatch 2 is regulated by advanced microprocessor technology for reliable and accurate readings. Additionally, the gas watch has a triple alarm feature to notify wearers of dangerous conditions. The flashing lights, audible buzzer, and vibration alert is sure to be noticed on the jobsite. The large digital LCD display screen with a backlight will also automatically activate and provide a readout of the gas conditions, PEAK, TWA, and STEL readings. The unit also notifies wearers of possible equipment malfunction. As can be expected, it also tells time.
Although the GasWatch 2 is designed for convenient use on the wrist, the device may also be worn on a belt, hard hat, or protective gear. RKI Instruments makes compatible clips for customers to use when wearing the GasWatch 2.
GasWatch 2 Specifications
Weighing in at approximately 2 ounces, the GasWatch 2 is extremely compact with dimensions of 2.5”W x 1.7”H x 0.9”D. The power source is one coin lithium battery (CR2450). The long life battery can operate for over 3,000 hours or 1 year of normal use with no alarms or backlighting. A typical response time for the unit is approximately 20 seconds for oxygen and 30 seconds for hydrogen sulfide and carbon monoxide. To preserve the integrity and security of the device, the unit is housed in a high-impact casing that is dust proof and weather proof.
The GasWatch 2 has been rated intrinsically safe and comes standard with a 2 year warranty for materials and craftsmanship.
