Great question - they're often confused, but they serve different purposes.

Bump Test: A quick functional check that exposes your detector to a known gas to verify the sensors respond. Takes about 30 seconds. Think of it as a "yes, it's working" check.

Calibration: A full adjustment of your detector's sensors to ensure accurate readings against a certified reference gas. This is what you need for compliance, audits, and true accuracy.

Our recommendation: Bump test before each use. Calibrate every 6 months (or per manufacturer guidelines). We'll even remind you when your units are coming due - ask us about our tracking service.

Absolutely - and here's the best part: K2 service customers get 50% off rental rates.

If your detector is in our shop for calibration or repair, you can rent a replacement unit at half price. Same-day shipping available so your crew never misses a beat.

Yes - every single calibration includes a NIST-traceable calibration certificate at no extra charge.

This certificate documents:

• Detector serial number and model
• Calibration date
• Gas concentrations used
• Pass/fail results
• Next recommended calibration date

It's exactly what you need for OSHA compliance, safety audits, and company records. Digital copies are available upon request.

We stand behind our repair work. Specific warranty terms depend on the type of repair:

• Sensor replacements: Covered by manufacturer sensor warranty (typically 2-3 years depending on sensor type)
• Component repairs: 90-day workmanship warranty on labor and parts

If something we repaired fails within the warranty period, send it back and we'll make it right. We're not here to nickel-and-dime you - we want customers for life.

Questions about a specific repair? Give us a call.

Most manufacturers recommend calibrating gas detectors every 6 months, though some environments or regulations may require more frequent calibration.

Signs your detector might need calibration now:

• It's been more than 6 months since the last calibration
• Failed bump tests
• Readings seem inconsistent or erratic
• Exposure to extreme conditions (heat, humidity, drops)
• Required for an upcoming audit or inspection

Pro tip: We keep track of calibration schedules for our repeat customers. We'll send you a reminder when your units are coming due. One less thing to track. Ask us about it.

We offer rush service for customers who need their equipment back ASAP.

Our standard turnaround is 3-5 business days, but if you're in a time crunch, give us a call at (949) 550-9777. We'll do everything we can to accommodate urgent jobs.
