The new RKI SP-220 Gas Leak Detector allows fast and reliable gas detection from a single instrument with a single sensor. Depending on the SP-220 model, you can detect up to 40 target gases including fumigants, toxics, freons, and combustible gases. Simply select a target gas and the RKI SP-220 will automatically adjust to factory or user set target points for that specific gas, keeping setup to a minimum. Response time is around 10 seconds, and the SP-220 will detect concentrations as low as 0.1 ppm.
The backlit LCD screen displays the currently selected gas, the gas concentration both numerically and through a bar graph, and the status of the pump, battery, pilot, and sound. The RKI SP-220 Gas Leak Checker alerts to high levels (factory or user-set) through both on screen and audible alarms. These can be user-customized as needed. Up to 256 data points can be stored to memory, including automatic storage of the highest measured reading. The Peak Hold function will constantly show the peak value of the current test period.
A calibration kit is offered for the RKI SP-220 which enables easy field calibration of the PH3 (phosphine) sensor. Protection is provided by the included rubber over-molded case, rated for ingress to IP55 as water-resistant and dust-proof. Two AA alkaline batteries will power the SP-220 for up to 12 hours, and a built-in LED provides light for dark work areas. Weighing just 7.5 ounces, the SP-220 is easily carried or mounted to clothing for continuous monitoring.
