475 MK III Handheld Digital Manometer is
ideal for field calibration, monitoring or trouble shooting HVAC systems,
clean rooms or a wide range of other low pressure pneumatic systems.
Large, 1/2" LCD display is easy to read - even in the poorest lighting
conditions, minimizing data collection errors. A single key instantly switches readout between English and metric pressure units so you don't have to calculate equivalents. Durable extruded aluminum housing provides complete protection for electronics. One-piece front membrane keeps dust and moisture out; wipes clean in seconds. Zero adjustment is conveniently located on top, no tools necessary. |
