Specialized manufacturer of Digital Pressure Meters and Load Cells
VGMH Series enables you to quickly check pressure and load* for easy analysis and calibration in the field!
* Strain gauge transducer
Using this hand-held meter, you can readily check the values of load cells or pressure sensors installed on the shop floor. This is helpful for pressure/load measurement in the field where signals can be checked only in distant locations or if you need to check one device after another. In a compact body that fits in one hand, it has advanced features such as color bar meter and graph overlay. Besides, VGMH Data Viewer can be downloaded free of charge. This data management software allows you to easily prepare various highly functional reports of distribution or transition of measurement data by connection with PC.
Pressure check on hydraulic equipment
Press and press-fit load control
Color graphic LCD screen
- Clear and easy-to-read color LCD
- Values on safe or hazardous levels can be intuitively color-coded.
Waveform & bar meter display
- Whether the measured value is proper, insufficient, or excessive can be intuitively grasped at a glance.
TEDS function(*1) (Transducer Electronic Data Sheet)
- Reads the sensor(*2) information to automatically, and records calibration values when the power is turned on.
- Sensor(*2) information can be displayed and rewritten.
Indicator value list
- This shows a list of recorded indicator values.
- Waveform screen can be recorded, displayed and compared.
Graph analysis and overlay functions
- Process reproducibility check
- Easy to understand graphs by comparison with data of non-defective products
Static Strain Disp. Mode
- Set whether to show the input signal(*2) with the strain amount.
- Use when checking sensor(*2) output and unsteadiness in indicator values, including for sensors and cables, and when making adjustments for discrepancies.
6 types of sensor (*2) data can be stored.
- Sensor (*2) specific values need not be input every time since they can be stored.
- Frequently used data sets and graphs can be called up quickly.
Languages support
- For use overseas (for business trips)
- You can select the language, Japanese or English.
Interrupted wire(*2) checking
- Wire disconnecting becomes readily apparent at a field.
- If the possibility of an interruption is detected, the location of the possible interruption will be shown in red.
Two sensor (*2) input lines
- Supports multiple measurements thanks to the enabled connector input and terminal block (loose wire) input.
Multiple power supply system
- Operation on four AA batteries power
- Micro-B USB port use to supply bus power
D/A output
- You can achieve analog output that corresponds to the full scale as voltage output within ±2V. Available as a dynamic strain amplifier.

(*1) This function is available for use in combination with the TEDS-compatible sensors.
(*2) Strain gauge transducers such as pressure sensors, load cells, torque sensors.
Data Management SoftwareVGMH Data Viewer
Measurement data can be saved in CSV (Excel) format on PC or arranged in a list to show whether they fall within the predetermined upper and lower limits.
Also, values involving time-series change can be plotted in graphs with ease.
"VGMH Data Viewer" is the software for management of data recorded by VGMH, and download free.
However, membership is required to download software.
