3. Main features:

◎ Adopts a high-definition LCD display, users can enjoy intelligent operations according to on-screen prompts, and each operation process is provided with Chinese character prompts and quantitative indicators.

◎ Powerful data processing capability, which can automatically submit parameters such as the average value, final value or peak value of the tested gelatin samples.

◎ Provides 4 sampling and measurement modes: single step, hold, cycle, and automatic, making your operation more handy.

◎ The automatic measurement mode can help you obtain the gel strength value faster, more accurately and closer to the actual value.

◎ Provides 5 sampling speeds: 0.1mm/s, 0.2mm/s, 0.5mm/s, 1mm/s, 2mm/s. Selecting high-speed measurement will not generate depth error of the probe pressing into the gelatin surface.

◎ Sampling depth can be preset arbitrarily (1mm--60mm).

◎ The instrument provides 2 types of sampling results. Combined with different test combinations of sampling speed and sampling mode, it submits either the final value or the peak value to users.

◎ Professional high-precision pressure sensor.

◎ High-precision mechanical transmission and is equipped with 4-level shockproof design.

◎ Users can verify the measurement accuracy of the instrument by themselves (using standard weights).

◎ Automatically corrects nonlinear errors, automatic fault diagnosis and alarm, automatic over-range protection, and automatic error correction prompts.

◎ Embedded micro printer, standard serial printing, convenient for storing experimental data.

2. Constant Temperature Water Tank and Refrigerator

1. Technical indicators:

● Water bath temperature control range (5～65.0)℃

● Water bath temperature control accuracy ±0.1℃

● Cooling time (30℃→10℃)＜40min

● Power supply 220V/50Hz/1200W

● External dimensions 0634B-1 (58×44×22)cm³

0634B-2 (48×38×29)cm³

2. Main features:

● The constant temperature water tank and refrigerator form a precision constant temperature cold water bath system.

● Adopts a magnetic water pump circulating water heating system, ensuring uniform water bath temperature.

● High-precision temperature sensor, with small linear error and high temperature measurement accuracy.

● Automatic frequency conversion control technology, intelligently controlling temperature with high temperature control accuracy.

● The refrigerator uses a high-reliability high-power new compressor for cooling, with fast cooling speed and low noise.

● Temperature can be preset arbitrarily; preset value and real-time value are displayed in a time-sharing manner.

● Automated, with automatic detection, automatic diagnosis and automatic alarm.

● The inner liner of the constant temperature water tank is made of high-quality stainless steel, with a wide temperature control range and beautiful appearance.

3. Test Method:

Take two 7.50g portions of the test substance, place each in a sample bottle, add 105g of water, seal with a rubber stopper, and place at room temperature for 1 to 4 hours to allow the test substance to fully absorb water and swell. Stir and heat in a water bath at 65℃±2℃ for 15 minutes to dissolve and disperse evenly. Place the sample bottle on a magnetic stirrer, remove the stopper, add a magnetic stirring bar, then replace the rubber stopper, and stir magnetically for 5 minutes to disperse the solution evenly and mix the water condensed on the inner wall of the sample bottle into the solution, preparing a 6.67% test gelatin solution. Place at room temperature until the temperature of the gelatin solution in the bottle drops to about 30℃; then place the sample bottle in a horizontally adjusted constant temperature water bath, incubate at 10℃±0.1℃ for 16 to 18 hours, quickly take out the sample bottle, wipe off the water droplets on the outer wall, remove the rubber stopper of the sample bottle, use a probe with a diameter of 12.7mm, at a descending speed of 0.5mm per second, and read the value generated when the probe is pressed down to 4mm below the surface of the gel. The gel strength shall be within ±20% of the indicated value, and the absolute difference between the measured values of the two test portions shall not exceed 10 Bloomg.
