That depends on the manufacturer…some say 30 days whereas others say 90 or 180 days. Typically the facility HSE will have a plan that includes calibration frequency. Otherwise, revert to manufacturer recommendations.

Every manufacturer recommends a bump-test before each days use, meaning if you are planning on using your meter, it must be bump tested before using it that day. A bump test is nothing more than applying a concentration of known gas in “normal running” mode to verify sensor response and alarms.
Note: Do NOT apply a high concentration of gas (CO- Engine Exhaust or Flammable Gas) as this will overdose the sensor and could lead to early sensor replacement.

  • Yes, but you must follow the directions on our website to ensure the shipment is properly prepared. Simple attach the “eco M/T” adapter to the empty bottle by screwing it into cylinder threads, which ensures the bottle is completely empty. Click on the “EcoSmart Returns” button on our website and complete the form for a Free Return label. Next place the empty cylinders in a box (with the “eco M\T” still attached to each bottle) and attach shipping label. No Hazmat paperwork is necessary since the “eco M/T” guarantees there is no pressure in the bottle.

While they can be the same bottle, the different terms mainly refer to how the gas is being used.

For Calibration, you may use a bottle as a part of a Calibration Kit which includes the bottle, regulator, tubing, and calibration adapter for the meter you are going to calibrate. When you calibrate, you are adjusting the values of the sensors in the meter that correlate to the concentration of the gases in your Calibration Gas cylinder. During Calibration the alarms are typically deactivated for a time period.

When you perform a Bump Test, you are simply applying the gas to the meter while in normal operation mode to confirm that the calibration has been accepted and the meter displays the gas concentrations (typically +\- 10%) of that in your cylinder. This also verifies that the visual and audible alarms are operating properly. The Bump Test may also be referred to as a Functional Test.

When ordering gas cylinders on our website, we recommend the correct cylinder threads for that specific size cylinder at the bottom of the page. If your meter has a pump attached for active sampling, a demand flow regulator (DFR) will be the correct option. If you have a personal meter, one that uses diffusion (no pump), a fixed flow regulator will be the correct option. Typically 0.5 Liters per minute (LPM) is the correct flow rate, but if needed, flow rates from 0.1 LPM to 6LPM can be ordered. If you currently have a bottle and need to know the correct model regulator, just click on the “ASK US!” button and send us a picture and we will quickly let you know the correct model needed for your specific cylinder.

Refer to the manufacturer recommendation first. If you have a mix specific that you want to setup your meter to use, depending on your specific brand\model of gas detector this may be done through the configuration menu. Refer to the manufacturer manual for instructions on how to change calibration gas concentration on your gas detector. You may also contact our trained technicians and we can configure your gas detector for you and verify the calibration is being performed properly.
