Benetech GM505 vs GM510 vs GM511 vs GM520 vs GM522 vs GM525 vs GT5101 Pressure Manometer Malaysia
Which Benetech Pressure Manometer Should You Choose?
Choosing a Benetech pressure manometer starts with the expected pressure and the required measurement method.
The GM505, GM510, GM511, GM520, GM522 and GM525 have individual catalogue-listed ranges. GT5101 is a series with multiple range options, including low-pressure versions starting at ±125 Pa.
For buyers in Malaysia, the model name alone is insufficient. Confirm the exact range, differential measurement capability and compatibility with the test medium before ordering.

GT5101 does not automatically provide every listed range in one instrument. Specify the required range when requesting a quotation.
GT5101 Range Options
The catalogue lists:
±125 Pa, ±250 Pa, ±0.5 kPa, ±1 kPa, ±2 kPa, ±2.5 kPa, ±4 kPa, ±5 kPa, ±10 kPa, ±40 kPa, ±50 kPa, ±100 kPa, ±200 kPa and ±700 kPa.
For reference:
±125 Pa = ±0.125 kPa.
±250 Pa = ±0.250 kPa.
±0.5 kPa = ±500 Pa.
Selecting a suitable low-pressure range matters when the expected pressure difference is small. Also confirm the display resolution and accuracy requirements rather than choosing solely by the maximum range.
GM505 vs GT5101 for Differential Pressure
The GM-series function table explicitly lists differential pressure measurement for GM505.
The GT5101 series is described as a differential pressure instrument with applications including fan and blower pressure, filter resistance, furnace pressure and orifice plate differential pressure.
Review GM505 when its ±2.49 kPa range suits the task.
Review a range-specific GT5101 when a lower or higher differential pressure range is required, or when its recording and PC functions match the inspection workflow.
GM510 vs GM511: Temperature Compensation
Both models list a ±10 kPa range.
The main difference shown is temperature compensation: GM510 is marked without it, while GM511 is marked with it.
Both have the same listed precision at 25°C. The catalogue does not quantify their accuracy across the full operating temperature range, so request further information if ambient temperature changes are important.
GM520 vs GM522: Match the System Pressure
The GM520 lists ±35 kPa, while GM522 lists ±100 kPa.
Choose a range that covers the expected pressure and normal fluctuations. Confirm the permitted overload pressure before connecting to a system.
A higher range should not be assumed to provide better results for small pressure changes. Review the resolution and allowable error for the actual measurement.
GM525: Confirm Its A+B Connector Function
The catalogue shows A+B connectors for GM525, but marks differential pressure measurement as unavailable in its function table.
This inconsistency needs clarification before selecting GM525 for a two-point pressure measurement.
Confirm the supported connection method from the current manual or manufacturer. Two connectors alone do not establish the measurement mode.
Comparing Accuracy Specifications
The GM models list ±0.3% FSO precision at 25°C.
GT5101 lists total error as:
±1% FS for ranges of ±1 kPa or greater.
±2% FS for ranges below ±1 kPa.
These specifications use different descriptions and conditions. Do not rank the instruments by percentage alone.
Ask for the applicable full-scale definition, display resolution and temperature conditions when determining whether a model meets a numerical inspection requirement.
Recording, USB and Power
All six GM models list USB interface, MAX/MIN/AVG readings, difference/record mode, reading hold, backlighting and automatic shutdown. The catalogue describes PC reading and data export through USB.
GT5101 lists USB connection, differential and record modes, data hold, reset/data adjustment, low battery indication and automatic power-off. PC software screenshots show measurement and settings interfaces.
Its listed power supply is a 1000 mAh rechargeable lithium battery. Confirm the supplied software, charging arrangement and recording capacity when ordering.
Temperature and Overload Limits
GT5101 lists:
Operating temperature: −10 to 60°C.
Temperature compensation range: −5 to 50°C.
Overload pressure: 3 × FS.
The GM models list 0–50°C operating temperature, but this catalogue page does not specify their overload rating.
Overload tolerance is not the normal measurement range. Operate within the rated range and confirm test-medium compatibility before use.
Benetech Pressure Manometer Enquiries in Malaysia
For customers in Selangor, Kuala Lumpur, Johor and Penang, contact MTM Precision Sdn Bhd with the expected pressure, test medium and required measurement method.
For GT5101 enquiries, specify the exact range, such as ±125 Pa, ±1 kPa or ±10 kPa. Send a photo of the connection point or system specification so we can help review the suitable configuration and quotation.
