Hazardous gas detector instrumentation calibration

Hazardous gas detectors may be fitted with a number of different sensors to detect a wide range of gases.
This listing details the traceable calibration gases currently held by JMW and the various hazardous gas detection instrumentation that JMW calibrate.

Calibration While-U-Wait
JMW offer a "calibrate while you wait service", telephone 01279 307100 to book an appointment.

Help Us To Help You
When sending items to JMW for calibration please ensure that you include the following:
Your name
Your full postal address
A valid email address
Your mobile telephone number

In general the accepted calibration interval for hazardous gas detectors is 6 calendar months.

JMW maintain a database of all previously calibrated equipment and advise the owner prior to the end of the calibration interval that recalibration is recommended.
