Calibration for 4-gas meters, single-gas monitors and PID instruments, done by OEM-certified technicians in our own San Antonio-area Repair Depot. Ship your detectors in, drop them off at our Universal City headquarters, or have our technicians calibrate them at your station on a set schedule.
Detectors only protect a crew when they read true. Every calibration we perform is built to give your crew a reading they can trust and a record your safety officer can show.
01
Check-in and screening
Your instrument is logged by serial number on arrival, with its warranty status and service history attached, then goes through our documented screening process and a functional check.
02
Certified calibration
Calibration on the manufacturer’s required cycle. Sensors that won’t hold calibration are identified for replacement, at no charge when the instrument is covered by a Honeywell Service Made Simple Enhanced agreement.
03
Certificate on file
A calibration certificate tied to the instrument’s serial number, kept on file for its whole service life. Need a copy for an audit? We can text or email it.
04
Repairs when needed
If the instrument needs more than calibration, our technicians repair it in-house. When it falls outside our in-house scope, we coordinate the manufacturer repair and handle the logistics.

Three ways to get it done
Drop-off, mail-in or on-site.
Drop-off or mail-in to the depot
Best for a few instruments, an overdue calibration or a detector that’s acting up. Open an RMA, then drop the instrument off at our Universal City headquarters (1500 Northlake Pass, Suite 101, Mon–Fri 8–5) or ship it in. It’s typically back in service in 48–72 hours.

On-site with a Service Program
Best for departments with a fleet of detectors. Our certified technicians come to you every 30 to 180 days, your choice of cycle, to test and calibrate gas, radiation and chemical detectors, replenish consumables and fix minor problems during the visit. If an instrument has to go to the depot, an express loaner covers you when required. One annual PO covers the program. See Service Programs
Sending an instrument

FAQ
Calibration questions.
How long does gas detector calibration take?
Depot work typically turns around in 48–72 hours from the time the instrument arrives. On a Service Program, calibration happens at your location during the scheduled visit.
How much does calibration cost?
We quote every job, because it depends on the instrument, its sensors and its condition. Request a quote for depot calibration, or ask for a Service Program estimate to cover your whole fleet on one annual PO.
Do you calibrate BW and RAE Systems 4-gas meters?
Yes. FarrWest is a Honeywell Authorized Service Provider for BW and RAE Systems gas detection. Instruments under a Honeywell Service Made Simple Enhanced agreement get covered parts and labor at no charge.
Will I get a calibration certificate?
Yes. Each certificate is tied to the instrument’s serial number and stored with its full calibration and repair history, so you can pull it for an audit or inspection.
Is there gas detector calibration near San Antonio?
Yes. Local agencies can drop instruments off at our Universal City headquarters, 1500 Northlake Pass, Suite 101, Monday to Friday 8 to 5. Agencies anywhere can ship instruments to the depot with an RMA, and our Service Program technicians work on-site in 10+ states.
