RKI 04 Series Single Gas (each)

The 04 Series toxic single gas monitor is designed to operate for many years with field replaceable sensors and filters. The HCN, NO2, PH3, and SO2 versions can be operated continuously for at least 3,000 hours on (2) AAA size alkaline batteries. The 04 models have 2 preset alarms that are user adjustable. Each version is also equipped with visual, audible, and vibration alarms as standard. Each 04 Series monitor is impact, dust, and water resistant with an IP-67 rating. 04 Series instruments are safe for use in hazardous locations, classified as intrinsically safe ATEX/IECEx and by QPS to U.S. and Canadian standards     for Class I, Division 1, Groups A, B, C, and D atmospheres. The replacement sensors are inexpensive, easily field replaceable, and are interchangeable with other popular RKI instruments like the GX-3R, GX-3R Pro, and GasWatch 3. * 3 year warranty on material and workmanship including sensors (1 year warranty for Ammonia and sensor) Model Name SC-04 HCN SC-04 NO2 SC-04 PH3 SC-04 SO2 CO-04 (-H2) CX-04 Gas Detected Hydrogen Cyanide Nitrogen Dioxide Phosphine Sulfur Dioxide Carbon Monoxide CO O2 Detection Principle Electrochemical Part# 73-0071 73-0073 73-0079 73-0083 73-0067 73-0069 Detection Range(Increments) 0 ~ 30.0 ppm(0.1 ppm) 0 ~ 20.00 ppm(0.05 ppm) 0 ~ 20.00 ppm(0.01 ppm) 0 ~ 100.0 ppm(0.05 ppm) 0 ~ 2000 ppm(1 ppm) 0 ~ 40%(0.1%) Alarm Set Points 1st: 5.0 ppm2nd: 10.0 ppm3rd: 30.0 ppmTWA: 4.7 ppmSTEL: 10 ppm 1st: 2.00 ppm2nd: b4.00 ppm3rd: 20.00 ppmTWA: 0.50 ppmSTEL: 1.00 ppm 1st: 0.30 ppm2nd: 0.60 ppm3rd: 0.60 ppmTWA: 0.30 ppmSTEL: 1.00 ppm 1st: 2.00 ppm2nd: 5.00 ppm3rd: 100.00 ppmTWA: 2.00 ppmSTEL 5.00 ppm 1st 25 ppm2nd 50 ppm3rd 1200 ppmTWA 25 ppmSTEL 200 ppm L: 19.5 %LL: 18.0%H: 25.0 % Alarm Types Gas alarms: 1st, 2nd and 3rd (user adjustable), OVER alarm, STEL and TWATrouble alarms: Sensor connection, low battery, circuit failure, and calibration range error Alarm Methods Gas alarm: Flashing LED’s, intermittent buzzer, flashing gas value, and vibrationTrouble alarm: Flashing LED’s, intermittent buzzer, and display of error messageSTEL & TWA alarms: Flashing LED’s, intermittent buzzer, flashing gas value, and vibration Gas Sampling Diffusion Response Time T90 in 30 seconds Accuracy(which ever is greater) ± 10% of readingor ± 5 % of full scale < 300 ppm ± 5 % of reading> 300 ppm ± 20 % of reading < 25% ± 0.5 %> 25% ± 3.0 % Data Logging 10 second intervals = 10 hours, 5 minute intervals = 300 hours, 10 minute intervals = 600 hours Instrument records alarms, alarm trends, gas readings, calibration & bump test history, instrument information and settings.
