ZHR-2 Penetrometer

Product Introduction
The ZHR-2 Penetrometer is a pharmaceutical testing instrument primarily designed to determine the consistency and penetration of ointments and ophthalmic ointments. Its design meets the requirements for the penetration test specified in the Chinese Pharmacopoeia.
The ZHR-2 ointment penetrometer is equipped with three types of cones and corresponding containers to accommodate different testing requirements. With an automated cone release and measurement system, the instrument provides accurate, fast and convenient penetration testing.
Its non-contact displacement sensor allows the cone to descend as close as possible to free-fall conditions, helping minimize mechanical interference during measurement.

Performance Features
• Automatic cone release: Automatic release mechanism with a measurement range greater than 65 mm.
• Non-contact displacement measurement: Minimizes mechanical resistance during cone descent.
• Automatic cone lifting: Cone and release mechanism can automatically move up and down.
• Fine platform adjustment: Precisely adjusts the distance between the sample surface and cone tip.
• Color LCD display: Easy operation with a Chinese menu interface.
• Statistical analysis: Software supports multiple measurements, average value and RSD calculation.
• Automatic printing: Test results can be printed directly.
• Integrated mechanical structure: Improves the verticality of the linear displacement sensor and platform levelness.
• Built-in LED illumination: Makes it easier to accurately observe contact between the cone tip and sample surface.
• Multiple cone options: Standard, 1/2 and 1/4 cone configurations are available for different sample containers.

Working Principle
The ZHR-2 Ointment Penetrometer determines sample consistency by measuring the depth to which a specified cone penetrates the sample under controlled conditions.
The test sample is placed in the corresponding container and positioned on the adjustable platform. The cone is aligned with the sample surface using the platform fine-adjustment mechanism. After the cone is automatically released, it descends under its own weight for a preset penetration time, typically within the specified 5–99 s range.
The non-contact displacement sensor accurately detects the vertical movement of the cone. The penetration depth is calculated from the measured displacement and displayed on the LCD screen. Multiple measurements can be performed, with the software calculating the average value and RSD and printing the test results.

• Universities and research laboratories
• Pharmaceutical R&D departments
It is particularly suitable for evaluating the consistency, penetration and physical properties of ointments and ophthalmic ointments.

Standards and Compliance
The ZHR-2 is designed according to the penetration test requirements of the Chinese Pharmacopoeia, making it suitable for pharmaceutical quality control and laboratory testing.

ZHR-2 vs. Conventional Manual Penetrometer

Feature	ZHR-2 Penetrometer	Conventional Manual Penetrometer
Cone Release	Automatic	Manual
Displacement Measurement	Non-contact sensor	Usually manual reading
Cone Movement	Automatic	Manual
Platform Adjustment	Fine adjustment mechanism	Basic/manual
Display	Color LCD	Mechanical or basic display
Statistical Calculation	Average and RSD	Usually manual
Result Printing	Supported	Usually unavailable
LED Illumination	Built-in	Usually unavailable
Testing Efficiency	High	Relatively low
Test Consistency	Improved automation	More dependent on operator

The ZHR-2 Penetrometer combines automatic cone release, non-contact displacement measurement, digital display and statistical analysis in one system. Compared with conventional manual penetration testing, it reduces operator intervention and improves testing convenience and measurement consistency.
