Gel Strength Tester

I. Model Advantages

1. Precision motion module with high-precision closed-loop servo motor ensures displacement accuracy of 0.001 mm (real-time display).

2. Premium force sensing element plus high-precision strain/bridge acquisition module ensures force accuracy of 0.001 g (real-time display).

3. Optional high-precision gel water bath with temperature control accuracy of 10±0.01 °C (automatic real-time monitoring).

4. The three key elements of gelatin gel strength measurement accuracy - force accuracy, displacement accuracy and temperature control accuracy - are all reliably guaranteed by hardware and monitored by software, providing professional users with authoritative, trustworthy, verifiable and traceable measurement results.

5. The instrument provides automatic verification, metrology and calibration functions for force accuracy; through continuous standard sample testing it determines whether measurement data are acceptable or out of tolerance and displays the result directly in the software, automatically completing metrology and calibration and printing a metrology report.

6. The probe measurement starting origin can be set quickly, arbitrarily and precisely, reducing auxiliary time and improving detection efficiency.

IV. Model Configuration

4.1 Gel strength tester three-piece set (real-time display of load force, displacement and time function measurement characteristic curves), 1 unit.

4.2 Cylindrical probe: diameter 12.700±0.010 mm, 1 piece.

4.3 Gel bottle (capacity = 150 mL, inner diameter = 59 mm, height = 85 mm), 16 sets.

V. Three-Piece Set Description

The three-piece set version integrates the gel strength tester with a precision constant-temperature cold water bath and a refrigeration unit as a complete working system. The constant-temperature bath uses a food-grade thickened stainless steel inner liner with a temperature range of 3 °C to 65 °C, and the refrigeration unit uses a stainless steel evaporator rated for continuous operation of more than 72 hours, providing a stable and reliable temperature environment for gelatin gel strength measurement.
