The Rigel 421, Digital Pressure Vacuum Meter is a versatile, high performance, combination digital pressure and vacuum meter. The pressure vacuum meter is designed for use in numerous medical and industrial applications and is compatible with a wide range of gases and fluids.
It is housed in a rugged aluminium case with a sealed membrane keypad. Models are available with accuracies of either 0.1% or 0.05% and various pressure ranges. The 0.1% model utilizes a silicon transducer and the 0.05% model utilizes a stainless steel transducer.
The Rigel 421, Digital Pressure Vacuum Meter displays its measurements in cmH20, mBar, inH20, mmHg and PSI. An option in the 0.1% replaces cmH20 with kPa. The instrument reads peak pressure and has an automatic zero. Its ¼ inch fitting is adaptable to any standard fitting. Either a 9V alkaline battery or an AC adapter supplies power. A data output connector is available as an option.
The Rigel 421, Digital Pressure Vacuum Meter is tough, reliable instrument that will meet the demanding measurement requirements of both in-house and field applications. Included with each instrument is a Certificate of Calibration traceable to NIST.
