The molbox1 + flow terminal represents a significant update to the molbloc/molbox gas flow calibration system. molbox1 + combined with molbloc flow elements enables you to achieve the lowest uncertainty available for gas flow meter and controller calibrations. A special configuration, molbox1+S, allows you to use molbloc-S sonic nozzle flow elements at higher pressures, greatly extending their usable flow rate.
 

• ±0.125% of reading uncertainty on mass flow measurements with molbloc-L and molbloc-S elements with premium calibrations.
• molbox1+S configuration gives extra range ability with molbloc-S elements without requiring vacuum pumps.
• Now use any molbloc element for both high and low pressure applications in the same gas.
• Even more robust internal pneumatic design.
