Gas monitors are made to be used on some of the toughest job sites in the world. Industrial chemical and gas facilities are made for production, not comfort, and the safety of the workers depends on gas monitors doing their job day in and day out. Because so much is riding on the accuracy of these gas detection devices, regular calibration and testing is necessary. When sensors wear out or are overloaded, or when regular maintenance and re-certification is required, it takes trained technicians to make sure the work is done right. Gas detectors all come with warranties, but they vary by manufacturer. Each manufacturer deals with their warranty issues differently. If you have problems with your monitor, and you're not sure if it's covered under warranty or not, here's what you need to do. Call us with your order number from PK Safety Supply, along with the model number and serial number of the device. If you can't find these numbers, or aren't sure which numbers we need, have the monitor handy and give us a call at 800-829-9580 so we can help you find them. You can also contact us online though our live chat. Our regular hours are Monday through Friday from 6am until 5pm Pacific Standard Time (PST). With the information in hand (or on the screen, as the case may be), we'll be able to tell you if the monitor is under warranty, or not. If it is still covered, we will issue you a Repair Authorization number (RA#), and provide you with an address to ship the monitor directly to the manufacturer. They will then evaluate the unit and repair or replace depending upon their analysis. Gas detectors that are past their warranty can often be repaired at our in-house facility by our factory-trained technicians. Once you contact us, if it is determined the monitor is past its warranty, we will ask you some questions about the issues your monitor is having and see if we think there is a chance to repair it. If we agree there is a chance to repair the unit, we’ll have you ship it to us. There is a $50 fee to examine the monitor. However, this initial fee is waived if our recommended repairs are authorized by you, or a new replacement unit is purchased. Once we receive the monitor, we will take it apart and see if there are any additional problems with the unit. After we understand the scope of the repairs, we will contact you with a complete estimate for the cost (including return shipping) before we do the work. Once you approve the estimate, we will make the necessary repairs to the unit and return it to you. Our repair fees are $70/hour for labor plus the price of parts. If you have questions about repairing your monitors, or the warranty that comes with your device, please contact us at www.pksafety.com.
