To assist in making informed decisions Gastech supplies you with a variety of calculators. These calculators can assist with converting:

• Your consumption of disposable calibration cylinders to cheaper high volume cylinders
• Chemical concentrations from PPM to %Volume and Combustibles
• Amp outputs from certain calibration gases
• Conversion of parameters such as distances or Watts to mA and current
• Cable sizes based on distances and resistance

Simply select the required calculation below and away you go!
