Product Specifications

Compatible RAE Systems MultiRAE Gas Monitors 

This calibration kit is intended for compatible RAE Systems MultiRAE portable gas detectors equipped with O2, LEL, CO, H2S, and PID sensors. 

The included four-gas calibration mixture supports calibration of the standard electrochemical and combustible gas sensors, while the 100 ppm isobutylene cylinder provides calibration gas for the PID sensor. 

Always verify sensor configuration, calibration gas compatibility, and manufacturer calibration procedures before use. 

Why Is Proper Gas Monitor Calibration Important? 

Routine calibration helps verify that gas detection instruments respond accurately to known concentrations of calibration gas. Proper calibration supports reliable monitoring of oxygen levels, combustible gases, toxic gases, and volatile organic compounds in industrial and hazardous work environments. 

Using the correct calibration gas concentrations and compatible accessories helps maintain gas detector performance and supports workplace gas detection programs.

Frequently Asked Questions About the RAE Systems MultiRAE Calibration Kit

1. What does this RAE Systems MultiRAE calibration kit include?

The kit includes two calibration gas cylinders, regulator(s), a calibration adapter with tubing, and a carrying case. One cylinder contains the four-gas mixture, while the second contains 100 ppm isobutylene for PID calibration.

2. What gases are included in the four-gas calibration cylinder?

The four-gas cylinder contains:

• 18% oxygen (O2)

• 10 ppm hydrogen sulfide (H2S)

• 50 ppm carbon monoxide (CO)

• 50% LEL methane (2.5% by volume)

3. Why does the kit include a separate isobutylene cylinder?

The PID sensor uses a separate reference gas for span calibration. This kit includes 100 ppm isobutylene for calibrating the VOC photoionization detector.

4. Which RAE Systems monitors is this calibration kit designed for?

It is intended for compatible RAE Systems MultiRAE Series instruments equipped with O2, LEL, CO, H2S, and PID sensors. Always verify your exact monitor model and sensor configuration before ordering.

5. Can the four-gas cylinder calibrate the PID sensor?

No. The four-gas mixture is intended for the LEL, oxygen, carbon monoxide, and hydrogen sulfide sensors. The PID sensor requires its own calibration gas, which is why the kit includes a separate 100 ppm isobutylene cylinder.

6. What is the shelf life of the calibration gases?

The product listing specifies a 24-month shelf life for the four-gas mixture and a 48-month shelf life for the 100 ppm isobutylene cylinder. Always check the expiration date printed on the actual cylinder.

7. How often should a RAE Systems MultiRAE monitor be calibrated?

Calibration frequency depends on the instrument model, operating conditions, sensor configuration, and workplace procedures. Follow the manufacturer's recommendations and applicable safety requirements. Perform bump tests or calibration checks as required by your facility's program, and calibrate when required by the instrument's instructions or after a failed accuracy check.

8. Is a bump test the same as calibration?

No. A bump test verifies that the sensors respond to gas and that the alarms activate. Calibration adjusts the instrument's readings against known gas concentrations. A bump test does not replace a required calibration.

9. Does this kit include the MultiRAE gas monitor?

No. This listing is for the calibration kit and its gas cylinders and accessories. The gas monitor is sold separately.

10. Why are two calibration gas cylinders necessary for this MultiRAE configuration?

The instrument has four sensors that use the specified four-gas mixture and a PID sensor that uses isobutylene. Separate cylinders provide the appropriate reference gases for both sensor groups.
