Description
LR-Cal HMG 1 Description
The portable digital handheld manometer LR-Cal HMG 1 are suitable to measure non-corrosive and non-ionic gases and fluids, e.g. air, dry gases, hydraulic fluids. They measure positive and negative pressure as well as differential pressure and are suited with a 3 1/2 digit LC display with 12.7 mm figures height. Optional versions with analogue output 0...1 VDC are available.
The construction with piezoresisitve measuring elements guarantees high responsibility and accuracy. The handhelds are powered by 9V battery type 6F22. (Low bat indication if voltage becomes too low). Each instrument is supplied with a measurement protocol.
Typical applications:
- Checking of air filter and vents
- Checking niveau of fluids (non-corrosive, non-ionic)
- Checking of air flow
- Checking of pressure in clean rooms
- Medical applications
Available types:
- Type LR-Cal HMG 1 : without analogue output
- Type LR-Cal HMG 1-A : WITH analogue output 0...1 V
