Frequently Asked Questions
What is isobutylene used for in this calibration gas?
Isobutylene is used as the PID (photoionization detector) sensor calibration reference in the GX-6100 when configured for VOC detection. The PID sensor responds to volatile organic compounds, and isobutylene is a standard reference compound used to span the PID response. This blend calibrates both the PID and the electrochemical gas sensors (H2S, CO, O2) in a single gas application.
Is 81-0143RK-04 compatible with other RKI monitors that have PID sensors?
This specific mix is listed for the GX-6100 and SDM-6100. Compatibility with other monitors — such as the GX-6000 or GX-Force with a PID option — depends on the sensor configuration and the concentrations specified in those monitors' calibration procedures. Call
800.829.9580 and reference the monitor model and sensor kit part number for a compatibility check.
How does this mix differ from the standard 81-0154RK-04 four-gas mix?
The standard
81-0154RK-04 contains H2S, CO, CH4, and O2 — for four-gas monitors without a PID. The 81-0143RK-04 adds isobutylene as a fifth component for PID sensor calibration. Do not interchange these mixes unless the monitor's calibration procedure explicitly allows it.
Why is calibration gas non-returnable?
Calibration gas is a hazardous material with a traceable certification lot. Once shipped, cylinders cannot be re-inspected or restocked. Confirm the monitor model and sensor configuration before placing an order. Call
800.829.9580 to verify compatibility before purchasing.
How should the 34-liter cylinder be stored?
Store upright in a cool, dry, ventilated area away from heat sources and incompatible materials. Secure the cylinder to prevent tipping. H2S-containing blends are reactive with certain metals — use the regulator supplied or recommended by RKI. Do not store in a vehicle or enclosed space without proper ventilation.
Can PK Safety service or calibrate the GX-6100?
Yes. PK Safety services RKI Instruments monitors in-house with factory-trained technicians, including the GX-6100 series. Services include PID sensor calibration and replacement, electrochemical sensor replacement, and full functional testing. Call
800.829.9580 to arrange service or request a return authorization.
