Hydrostatic Pressure Tester GT-C26B-2


Application for hydrostatic head tester:

High pressure-servo Fabric Hydrostatic Head Pressure Test Machine is used to test the waterproof properties of fabric through waterproofing work such as canvas, coated fabrics, hood fabric, tarpaulin, rain-proof fabrics and geotextile.

Standards for hydrostatic head tester:


AATCC 127 Option 2, ISO 811, ISO 1420, GB/T 4744, GB/T 9082,

FZT 01004 ,DIN 53886 , EN 20811, EN 13726-3, EN 1734, BS 2823, WSP 80.6,

JIS L1092-7.1.1 Method A, JIS L1092-7.1.2 Method B (require at lest 500kpa)

Feature of Fabric Hydrostatic Head Pressure Tester


1. The pressure using dynamic feedback regulation effectively prevent pressure overshoot. 

2. Taiwan DELTA servo motor and drive system, 16-bit A/D conversion.

3. Hydrostatic head tester -whole machine with aluminum alloy structure.

4. Sensor protection: automatic overload protection ( automatic switching of multi-sensor range).

Mask Synthetic Blood Penetration Tester GT-RA01


Product Introduction


Mask Synthetic Blood Penetration Tester determine the resistance of medical protective masks to the penetration of synthetic blood under different test pressures. This Mask Testing Equipment can also be used to determine the blood penetration resistance of other coating materials.



GB 19083 section 5.5, YY/T 0691, YY 0469 section 5.5
ISO 22609, BS EN 14683
ASTM F2100, ASTM F1862

Instrument characteristics

1. The convex sample fixing device can simulate the actual state of use of a mask, leave a test target area without damaging the sample, and distribute the synthetic blood in the target area of the sample.

2. The special constant pressure spray device can spray a certain volume of synthetic blood in a controlled time.

3. GESTER Medical Face Mask Synthetic Blood Penetration Tester can fully simulate the human body's average blood pressure of 10.6kPa, 16kPa, and 21.3kPa spray speeds for testing.

4. Synthetic blood penetration resistance tester equipped with a target plate, which can block the high-pressure edge portion of the sprayed liquid flow, and only let the steady-state flow portion be sprayed on the sample, which increases the accuracy and repeatability of the liquid velocity sprayed on the sample.

Face Mask Differential Pressure Tester GT-RA04


Product Introduction



Face Mask Differential Pressure Tester is used to measure the air exchange pressure of the medical face mask or other fabric.


YY 0469 Section 5.7, YY /T0969 Section 5.6
ASTM F2100 Standard Specification for Performance of Materials Used in Medical Face Masks
BS EN 14683 Medical face masks - Requirements and test methods, section 5.2.3, Annex C


1. Adopt suction air source as the power source of the instrument, not limited by the space of the test site;
2. Medical Face Mask Air Exchange Pressure Difference Tester equipped with high-precision pressure difference sensor, digitally display the pressure difference on both sides of the sample;
3.The special sample holder ensures that the sample is firmly held.

Mask & Respirator Breathing Resistance Tester GT-RA03

Product Introduction



Mask & Respirator Breathing Resistance Tester can be used to determine the inspiratory and expiratory resistance of masks under specified conditions.Another additional function of this machine is flow impact test of the breather valve. The flow rate for inhale resistance test is 30L/min and 95L/min. The flow rate for exhale resistance test is 160L/min. And the flow rate for the flow impact test is 300L/min.


EN149-2009 section 7.15, 8.3.4, EN 13274-3, GB 19083, GB 2626, GB/T 32610

NIOSH 42 CFR Part 84, JIS/T 8151



  • Mask and Respirator Breathing Resistance Tester Touch-screen control, English menu, interactive mode, easy to operate.

  • Built-in thermal printer, easy to print test results quickly

  • Mask Resistance Tester High precision differential pressure sensor,digital flow meter with high accuracy.

  • Mask Respiratory Breathing Resistance Tester Can be set inhale test modes and exhale test modes.

  • Respirator pipe line automatic switch device can help test person avoid to pull out and connect the pipe line in wrong way when doing tests.

  • 3D standard head-form, 5 directions can be adjusted, simulates human real inhaling and exhaling to improve the accuracy of results.
