Pressure Measurement & Control


Handheld manometer used for high accuracy measurements

July 2006 Pressure Measurement & Control

The Blue Line series of digital, handheld manometers is manufactured by Afriso and supplied by Instrotech. This series has been designed for high accuracy pressure, vacuum and differential pressure measurements in gases.

These units are supplied in four ranges to cover a wide range of applications such as measuring burner pressure or gas-fired boilers, differential pressures across filters and pressure level switch setting. The Blue Line is a suitable replacement for U and J type liquid manometers, which are known to have inherent disadvantages.

The high measuring range is 0 to ±1,999 kPa (±19,99 mbar) up to 0 to (±1,999 bar) or on a second low measuring of range 15 kPa to 200 kPa (150 mbar to 2 bar). The maximum resolution on the low range is 0,01 mbar on the 150 mbar unit and 0,1 mbar on the 500 mbar, 1000 mbar and 7000 mbar unit.

This manometer features a large 12,7 mm 3½ digit LED display which incorporates a low battery status indicator (expected operating life is 100 hours). Operation is via an easy to clean membrane keypad for on/off, range switching and auto zeroing functions.

A protective holster is supplied as standard while the carrying case is an optional extra.
