Can We Help You?
Our product experts are here to help you find the right solution for your application!The M1 Series of handheld manometers from Meriam Process Technologies combines form, fit and function to deliver precision pressure measurement for field, plant or lab use. For reference indication and shirt pocket convenience, select the low cost M100 Digital Manometer with its ± 0.25% FS accuracy. When better accuracy is needed, specify the M101 Calibrator. The M101 delivers ± 0.1% FS accuracy and additional features normally found on higher priced instruments. Both models are available in differential, gauge and absolute pressure versions.
Typical applications include leak testing for low pressure gas systems, pressure drop monitoring across filters, monitoring vacuum on condensers or pumps and verification of CPAP or BIPAP systems for home or hospital settings.
