Kobata DMH-01 Series Portable Digital Manometer

Made in Japan
Manufacturer: Kowata Keiki Seisakusho Co., Ltd.
Model: DMH-01 Series: DMH-01-4kP, DMH-01-10kP, DMH-01-40kP, DMH-01-100kP, DMH-01-1MP

- By connecting with a USB cable, the DMH-01 main unit can be controlled from the included software, allowing you to measure while monitoring detailed waveforms of measurement data and record data to a PC.
- On-site measurements can be performed using only the DMH-01 main unit, and the data recorded in the main unit’s memory can be downloaded at high speed after measurement, allowing detailed data to be checked on a PC. Detailed analysis and processing can be performed using software, etc.
- It is now possible to set two threshold lines (red and blue).
- The saved data is in CSV format (tabular text file), so detailed analysis and processing can be performed using a spreadsheet program, etc.
- We provide separate Excel macros for displaying the Max, Min and Ave values for a specified section, as well as for unit conversion and flow rate measurement.
- This software is compatible with all DMH-01 series devices, so you can manage multiple DMH-01 series devices at the same time.
Optional Support
- Pressure connection ports can accommodate hoses of different diameters and medical luer taper fittings
- The measurement units are meters of water column and meters of mercury column for medical use, which are excluded from the Japanese Measurement Act.
Inspection report, etc.
