M200LS lab-standard, smart, digital manometer provides a NIST-traceable accuracy of ±0.01% of full scale from 15 °C to 30 °C and ±0.025% of full scale from -20 °C to 15 °C and 30 °C to 50 °C. Pressure ranges from 28 in. H2O full scale to 500 psig full scale are available. M2 pressure sensors are available to measure gauge, differential, absolute or vacuum pressure.
