M1 Series Digital Manometer
Precision at an unbelievable price!

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. Or specify the M101 
Calibrator when better accuracy is needed for more exacting measurements. The M101 delivers +/- 0.10% FS 
accuracy and additional features normally found on higher priced instruments. Both models are available in 
differential, gauge and absolute pressure versions.
