The Accupoint 2 is an advanced moisture analyzer equipped with a microprocessor and an integrated two-stage pressure regulator. With a wide operating range from 50 to 3000 psig, it is perfectly suited for most industrial, natural and process gas flows, ensuring optimal and accurate performance.

Characteristics:

Units of measure: microprocessor-based electronics allow a choice of display options, including ppmV, ppmW, lbs/mmscf or °C and °F dew point.
Three-button user interface: the Mode/Enter key, together with the simple Up and Down keys, make menu use quick and easy.
LCD display: the integrated digital display allows direct indication at the point of use and quick setting of control parameters in the field.
Scalable output: flexibility to change output scales in the field. No need to replace electronic components. Simply access the menu via the Mode/Enter key and select the output scale.
2-wire or 3-wire modes: standard simplicity of a 2-wire loop-powered transmitter or additional RS-232 output function in 3-wire mode.
In-line verification: use the simple Delta Flow procedure to quickly verify the linearity and performance of the sensor in-line.
