Benetech GM505 vs GM510 vs GM511 vs GM520 vs GM522 vs GM525 Digital Pressure Manometer Malaysia
Which Benetech Pressure Manometer Should You Choose?
The Benetech GM505, GM510, GM511, GM520, GM522 and GM525 offer different pressure ranges and connection arrangements.
For buyers in Malaysia, selection should start with the expected pressure, required measurement method and compatibility with the test medium.
Pressure range and differential pressure capability are separate considerations. A higher-range model is not automatically the best choice for a low-pressure application.

All six models list ±0.3% FSO precision at 25°C and a 0.5-second response time.
The catalogue does not provide display resolution in this table. Do not assume that every model offers the same ability to resolve small pressure changes.
Functions Shared Across the Range
The catalogue lists the following functions for all six models:
USB interface.
Maximum, minimum and average readings.
Difference/record mode.
Pressure unit selection.
Reading hold.
Backlighting.
Automatic shutdown.
It also describes data saving and PC reading/export through USB. Confirm the supplied software, computer compatibility and recording capacity if these are required for reporting.
GM505: The Lowest Listed Pressure Range
The GM505 has a range of ±2.49 kPa and is the only model explicitly marked as supporting measurable differential pressure in the function table.
It is therefore the first model to review when an application requires a pressure difference between two points within this range.
For example, a buyer investigating an air-system pressure difference should confirm the required range, connection method and test-medium compatibility before ordering.
GM510 vs GM511: Temperature Compensation
Both GM510 and GM511 list a ±10 kPa range and the same precision specification at 25°C.
The main functional difference shown is:
GM510: no temperature compensation listed.
GM511: temperature compensation listed.
The catalogue does not state the compensation performance across the full operating temperature range. Request further specifications if changing ambient temperature is important to the measurement.
GM520 vs GM522: Match the Expected Pressure
The GM520 provides a listed range of ±35 kPa, while GM522 extends this to ±100 kPa.
Choose a range that covers the expected pressure with suitable allowance for normal fluctuations. Also confirm the instrument’s permitted overload pressure, which is not specified on this catalogue page.
A ±100 kPa range is not a general-purpose compressed-air rating. Check the actual system pressure before connecting any model.
GM525: Confirm the A+B Connection Function
The catalogue shows A+B connectors for GM525, but its function table marks differential pressure measurement as unavailable.
This needs clarification before selecting GM525 for a two-point pressure measurement.
Two connectors alone do not establish the supported measurement mode. Request the current operating manual or written manufacturer confirmation for the exact GM525 supplied.
Difference Mode Is Not Proof of Differential Capability
All six models list difference/record mode, while the separate differential-pressure row marks only GM505.
Do not treat these descriptions as interchangeable. Confirm whether the required task is:
Pressure relative to atmosphere.
Pressure difference between two connected points.
A change in reading relative to a stored reference.
The correct instrument and connection method depend on this distinction.
Understanding the Accuracy Specification
The listed precision is ±0.3% FSO at 25°C, rather than ±0.3% of the displayed reading.
This matters when measuring a small pressure with a much higher-range instrument. Ask for the manufacturer’s definition of FSO, display resolution and applicable accuracy conditions when checking suitability.
The catalogue also lists 0–50°C operating temperature, −10–60°C storage temperature, and Err.1/Err.2 indications for readings beyond the positive or negative range. These indications do not establish overload protection.
